呼吸事件，是临床患者发生的与呼吸状态相关的异常情况。一种常见的呼吸事件为呼吸暂停。呼吸暂停，表现为患者自主呼吸停止，若不能及时救治可能对患者造成更为严重的伤害。呼吸暂停监测常见于对新生儿的监护中。具体地，新生儿尤其是早产儿，由于各个器官发育不足，常伴有呼吸暂停问题。患儿的胎龄越小，呼吸暂停问题发生的比例及频率越高。长时间的呼吸暂停会导致患儿各器官组织供氧不足，直接威胁患儿的生命健康。当然，呼吸事件还可以包括其他。Respiratory events are abnormal conditions related to respiratory conditions that occur in clinical patients. A common respiratory event is apnea. Apnea, manifested as the patient's spontaneous respiratory arrest, if not treated in time may cause more serious harm to the patient. Apnea monitoring is common in the monitoring of newborns. Specifically, newborns, especially premature babies, often suffer from apnea due to insufficient development of various organs. The younger the child's gestational age, the higher the rate and frequency of apnea problems. Prolonged apnea can lead to insufficient oxygen supply to children's organs and tissues, directly threatening the life and health of children. Of course, breathing events can also include others.
呼吸事件在历史一段时间内的发生情况，可以在一定程度上反映患者的呼吸氧合状况。The occurrence of respiratory events over a period of time can reflect the patient's respiratory oxygenation to a certain extent.

具体实施方式detailed description
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。In the following, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
临床医护人员，除了监测患者是否发生呼吸事件，还比较重视呼吸事件的发生频率。因为如果发生频率变大，即使患者能自主恢复，也可能预示患者呼吸氧合状况在恶化，需要尽早进行治疗。如果医护人员通过手动方式记录呼吸事件，可能由于不能一直守护在患者旁边，而错过某些患者自主恢复正常的呼吸事件，导致记录的呼吸事件次数明显少于患者真实发生的次数。Clinical medical personnel, in addition to monitoring patients for respiratory events, also pay more attention to the frequency of respiratory events. Because if the frequency of occurrence increases, even if the patient can recover spontaneously, it may indicate that the patient's respiratory oxygenation situation is deteriorating, and treatment is needed as soon as possible. If medical personnel record respiratory events by manual means, they may not be able to stay by the patient all the time, and miss some patients' spontaneous recovery of normal respiratory events, resulting in significantly fewer recorded respiratory events than the actual number of patients.
因此，可以由医疗设备自动监测呼吸事件的发生，并对其进行记录。医护人员可以在医疗设备上，回顾患者在历史时间段内发生的呼吸事件，以了解患者的呼吸状况。Therefore, medical equipment can automatically monitor the occurrence of respiratory events and record them. Medical personnel can review the breathing events of patients during historical periods on medical devices to understand the breathing conditions of patients.
本申请提供了一种呼吸事件的回顾显示方法，该方法可以应用在任意形式的医疗监护***上。医疗监护***可以理解为一个单一的医疗设备，例如监护仪、有创呼吸机、无创呼吸机等；也可以理解为多个医疗设备共同构成的***，例如床旁设备与护士站/中央站共同构成的***。下面实施例则主要以监护仪为例进行说明。This application provides a retrospective display method of respiratory events, which can be applied to any form of medical monitoring system. The medical monitoring system can be understood as a single medical device, such as a monitor, invasive ventilator, non-invasive ventilator, etc .; it can also be understood as a system composed of multiple medical devices, such as bedside equipment and a nurse station / central station. Composition of the system. The following embodiments are mainly described by taking a monitor as an example.
见图1，该方法具体包括步骤1.1-1.4。As shown in Figure 1, the method includes steps 1.1-1.4.
步骤1.1：获取目标对象在预设时间段内发生的呼吸事件，所述呼吸事件至少包括呼吸暂停事件；所述呼吸事件从至少一个生理体征参数传感器采集到的至少一种生理体征参数的信号中识别得到。Step 1.1: Obtain a breathing event of the target object within a preset period of time, the breathing event including at least an apnea event; the breathing event is in a signal of at least one physiological sign parameter collected from at least one physiological sign parameter sensor Recognized.
其中，本步骤的执行可以基于触发指令，例如医疗设备上可以设置回顾实体按钮，用户可以操作回顾实体按钮以生成触发指令，又如医疗设备显示的主监测界面中包含回顾图标，用户可以触控该回顾图标以生成触发指令。The execution of this step can be based on a trigger instruction. For example, a review entity button can be set on the medical device, and the user can operate the review entity button to generate a trigger instruction. For example, the main monitoring interface displayed by the medical device includes a review icon, and the user can touch The icon is reviewed to generate trigger instructions.
接收到触发指令后，从设备中获得被监测对象在预设时间段内发生的呼吸事件。为了便于描述，可以将被监测对象称为目标对象。目标对象可以是新生儿，也可以是其他类型的患者。记录呼吸事件的设备可以是应用呼吸事件回顾显示方法的医疗设备，也可以是其他设备。After receiving the trigger instruction, the breathing event of the monitored object within a preset time period is obtained from the device. For ease of description, the monitored object may be referred to as a target object. The target audience can be newborns or other types of patients. The device for recording the respiratory event may be a medical device to which the respiratory event review display method is applied, or it may be another device.
呼吸事件表示的是与呼吸相关的体征状态为异常情况，呼吸事件具体可以包括呼吸暂停事件、呼吸氧合事件等具体事件。在本步骤中，所获得的呼吸事件中至少包含呼吸暂停事件。The respiratory event indicates that the status of the signs related to breathing is abnormal. The respiratory event may include specific events such as an apnea event and a respiratory oxygenation event. In this step, the obtained breathing event includes at least an apnea event.
呼吸暂停事件、呼吸氧合事件是两种不同的呼吸事件类型，呼吸暂停事件较为严重，呼吸氧合事件相对呼吸暂停事件，严重度稍低，但是仍然需要对医护人员进行警告，使他们加以关注。Apnea event and respiratory oxygenation event are two different types of respiratory events. The apnea event is more serious. The respiratory oxygenation event is less severe than the apnea event. .
呼吸暂停事件相对呼吸氧合事件而言，触发条件相对较严格，可以体现在用于触发事件的生理体征参数种类更多、生理体征参数更能表示呼吸问题的严重性或者触发条件中的参数阈值更严格。The apnea event is more stringent than the respiratory oxygenation event, which can be reflected in more types of physiological signs parameters used to trigger the event, physiological signs parameters can better indicate the severity of breathing problems, or parameter thresholds in trigger conditions Stricter.
例如，呼吸事件涉及三个生理体征参数，分别为呼吸暂停时长、血氧饱和度、及心率，可以使用Apnea(或简称为A)表示呼吸暂停，Desaturation(或简称为D)表示低血氧饱和度，Bradycardia(或简称为B)表示与心率相关的心动过缓。For example, a respiratory event involves three physiological sign parameters, namely apnea duration, blood oxygen saturation, and heart rate. Apnea (or simply A) can be used to indicate apnea, and Desaturation (or simply D) can be used to indicate hypoxemia. Degree, Bradycardia (or B for short) indicates bradycardia associated with heart rate.
呼吸暂停事件的触发条件可以是：ABD、AB、AD、A、ABDn、ABn、ADn、An中的任意一种，其中n表示呼吸暂停时长。例如，A20表示单呼吸暂停持续了20秒，AB15表示呼吸暂停持续了15秒同时伴有心率过低。The triggering condition of the apnea event may be: any of ABD, AB, AD, A, ABDn, ABn, ADn, An, where n represents the duration of the apnea. For example, A20 indicates that a single apnea lasted 20 seconds, and AB15 indicates that the apnea lasted 15 seconds with a low heart rate.
呼吸氧合事件的触发条件可以是BD、B、D中的任意一种。The triggering condition of the respiratory oxygenation event can be any one of BD, B, and D.
需要说明的是，触发条件中包含哪种生理体征参数，则表示哪一种生理体征参数的数值达到了相应的参数阈值；如果判定条件中包含多种生理体征参数，则表示触发呼吸事件时要求该多种生理体征参数同时达到相应的参数阈值。It should be noted that which physiological sign parameters are included in the trigger condition, which indicates which value of the physiological sign parameter has reached the corresponding parameter threshold; if the determination condition includes multiple physiological sign parameters, it indicates that the trigger is required for triggering a respiratory event. The multiple physiological signs parameters simultaneously reach the corresponding parameter thresholds.
可见，呼吸氧合事件的触发条件相较于呼吸暂停事件而言，判定条件较为宽松。但两者都是呼吸状态异常的事件，因此可以统称为呼吸事件。呼吸事件是呼吸暂停的相关状态。It can be seen that the triggering conditions of respiratory oxygenation events are more relaxed than the apnea events. But both are events with abnormal breathing conditions, so they can be collectively referred to as breathing events. Respiratory events are related states of apnea.
呼吸事件是从生理体征参数的信息中识别出来的，以下首先说明如何根据生理体征参数识别目标对象是否发生了呼吸事件。The respiratory event is identified from the information of the physiological sign parameters. The following first explains how to identify whether a respiratory event has occurred in the target object based on the physiological sign parameters.
生理体征参数除了血压、心电、体温等参数外，为了实现对目标对象呼吸暂停相关状态的监测，还应该至少包括与呼吸暂停状态相关的生理体征参数，例如心率、脉率、血氧相关参数、呼吸率/呼吸波形等。其中根据呼吸率/呼吸波形可以确定呼吸暂停持续时长。需要说明的是，所获取的这些生理体征参数是基础数据，用于判断是否能够触发呼吸事件。当然，在其他实施例中，也不排除在进行呼吸暂停相关状态判断时采纳其他生理参数进行考量。In addition to parameters such as blood pressure, ECG, and body temperature, in order to monitor the apnea-related state of the target subject, the physiological sign parameters should also include at least the physiological sign parameters related to the apnea state, such as heart rate, pulse rate, and blood oxygen related parameters , Respiratory rate / respiratory waveform, etc. The duration of apnea can be determined based on the breathing rate / breathing waveform. It should be noted that the obtained physiological sign parameters are basic data and are used to determine whether a respiratory event can be triggered. Of course, in other embodiments, it is not excluded that other physiological parameters are taken into consideration when determining the state of apnea.
传感器所采集到的生理体征参数可以发送至监护仪的存储模块进行存储，这些基础数据可以作为分析数据，用于对呼吸暂停相关状态的各种呼吸事件如呼吸暂停事件、呼吸氧合事件进行分析。也就是说，生理体征参数可以是传感器将生理体征参数存储至医疗设备的存储模块中，本申请再从存储模块中获得。当然，生理体征参数也可以直接从传感器处获得。The physiological sign parameters collected by the sensor can be sent to the storage module of the monitor for storage. These basic data can be used as analysis data to analyze various respiratory events such as apnea events and respiratory oxygenation events in apnea-related states. . That is to say, the physiological sign parameters may be that the sensor stores the physiological sign parameters in a storage module of the medical device, and this application obtains them from the storage module again. Of course, physiological parameters can also be obtained directly from the sensor.
获得生理体征参数后，根据呼吸事件的各个认定标准(或称为触发条件、判定条件)，判断生理体征参数是否满足某一认定标准，如果满足某一认定标准，则表示发生与该认定标准对应的呼吸事件。以呼吸暂停事件为例进行说明。After obtaining the physical sign parameters, it is determined whether the physiological sign parameters meet a certain recognition standard according to each recognition standard (or triggering condition, judgment condition) of the respiratory event. If it meets a certain recognition standard, it means that a correspondence with the recognition standard has occurred Breathing event. Take the apnea event as an example.
呼吸暂停事件的认定标准可能有多种，认定标准不同监护仪的报警情况也不同。如果呼吸暂停事件的认定标准较低，例如将周期性呼吸等轻度呼吸事件也认定为呼吸暂停事件，则会频繁地报警，导致医护人员频繁地启动紧急处理程序，浪费医疗资源。There may be multiple criteria for the identification of apnea events, and different monitors will have different alarm conditions. If the apnea identification criteria are low, for example, mild breathing events such as periodic breathing are also recognized as apnea events, frequent alarms will occur, causing medical staff to frequently initiate emergency procedures and waste medical resources.
然而，本申请中的呼吸暂停事件，生理体征参数及参数阈值是对新生儿的呼吸暂停问题深入研究后确定的。However, the apnea events, physiological signs parameters, and parameter thresholds in this application are determined after in-depth research on the apnea problem of newborns.
具体地，对新生儿的呼吸暂停进行研究后发现，严重的呼吸事件大多与呼吸暂停持续时长有关，呼吸暂停持续时长越长表示情况越严重，因此将呼吸暂停持续时长确定为呼吸暂停事件的一个主要考量参数。研究还发现在出现呼吸暂停的过程中，也通常伴随有低血氧或心动过缓的症状。因此，将血氧饱和度值及心率(或脉率，由于脉率与心率通常表示了相同的生理状态，本实施例主要以心率进行说明)作为呼吸暂停事件的另外两个重要考量参数。Specifically, after research on neonatal apnea, it was found that most severe respiratory events are related to the duration of apnea. The longer the duration of apnea, the more serious the situation. Therefore, the duration of apnea is determined as one of the apnea events. Main consideration parameters. Studies have also found that in the process of apnea, it is often accompanied by symptoms of hypoxemia or bradycardia. Therefore, the blood oxygen saturation value and the heart rate (or pulse rate, because the pulse rate and the heart rate usually indicate the same physiological state, this embodiment is mainly described by the heart rate) are used as two other important parameters for apnea events.
根据临床观察发现，严重的呼吸暂停事件，呼吸暂停持续时长一般超过20秒，或者呼吸暂停持续时长超过10秒且伴随有血氧饱和度值小于80％，或者呼吸暂停持续时长超过10秒且伴随有心率低于100bpm(Beat Per Minute， 每分钟节拍数)。根据一判定条件，来设置呼吸暂停事件的生理体征参数的阈值。当然，以上数值也可以是根据实际监测需求而设置的其他值，本申请并不做具体限定。According to clinical observations, severe apnea events usually last longer than 20 seconds, or the duration of apnea exceeds 10 seconds with an oxygen saturation value of less than 80%, or the duration of apnea exceeds 10 seconds and is accompanied by Have a heart rate below 100 bpm (Beat, Minute, beats per minute). According to a determination condition, a threshold value of a physiological sign parameter of the apnea event is set. Of course, the above values may also be other values set according to actual monitoring requirements, which are not specifically limited in this application.
总结来看，与呼吸暂停事件相关的目标生理体征参数可以包括三个参数，即呼吸暂停持续时长、血氧饱和度值、以及心率，这些生理体征参数具有各自对应的阈值，当其中的一个或多个参数达到上述的判定条件时，表明出现了呼吸暂停事件。以上仅仅是一种具体的认定标准，在实际应用中，还可以是上述提及的判定条件中的任意一种。In summary, the target physiological sign parameters related to the apnea event can include three parameters, namely the duration of apnea, the value of blood oxygen saturation, and the heart rate. These physiological sign parameters have their respective corresponding thresholds. When one of them or When multiple parameters meet the above-mentioned determination conditions, it indicates that an apnea event has occurred. The above is just a specific identification standard. In practical applications, it can also be any of the above-mentioned determination conditions.
步骤1.2：确定所述呼吸事件的事件类型标记，所述事件类型标记表示触发所述呼吸事件的对应的生理体征参数的类型。Step 1.2: Determine an event type flag of the respiratory event, where the event type flag indicates a type of a corresponding physiological sign parameter that triggers the respiratory event.
在一种实施例中，确定呼吸事件的事件类型标记的方式，包括：获得目标对象与呼吸相关的生理体征参数，分析生理体征参数是否能够触发呼吸事件，其中呼吸事件包括呼吸暂停事件或呼吸氧合事件；若是，在生理体征参数中，确定用于触发呼吸事件的目标生理体征参数，并基于目标生理体征参数，确定呼吸事件的类型。In one embodiment, a manner of determining an event type marker of a breathing event includes: obtaining a breathing-related physiological sign parameter of a target object, and analyzing whether the physiological sign parameter can trigger a breathing event, wherein the breathing event includes an apnea event or breathing oxygen If yes, among the physiological sign parameters, determine a target physiological sign parameter for triggering a breathing event, and determine a type of the breathing event based on the target physiological sign parameter.
也就是说，触发条件中包含哪个或哪些生理体征参数，则表示该或该些生理体征参数的数值达到了相应的参数阈值。目标生理体征参数是所满足的触发条件中包含的生理体征参数，目标生理体征参数可以确定呼吸事件的事件类型。That is, which physiological sign parameter or parameters are included in the trigger condition, it means that the value of the physiological sign parameter or the physiological sign parameters has reached the corresponding parameter threshold. The target physiological sign parameter is a physiological sign parameter included in a satisfied trigger condition, and the target physiological sign parameter can determine an event type of a respiratory event.
例如，目标对象的生理体征参数中，呼吸暂停时长A及心率B同时满足触发条件，则目标生理体征参数为该两个生理体征参数，进而将呼吸事件的事件类型确定为AB。又如，目标对象的生理体征参数中，呼吸暂停时长A及血氧饱和度D同时满足触发条件，则目标生理体征参数为该两个生理体征参数，进而将呼吸事件的事件类型确定为AD。再如，目标对象的生理体征参数中，血氧饱和度D满足触发条件，则目标生理体征参数为该生理体征参数，进而将呼吸事件的事件类型确定为D。For example, among the physiological sign parameters of the target object, the apnea duration A and the heart rate B meet the trigger conditions at the same time, then the target physiological sign parameters are the two physiological sign parameters, and the event type of the respiratory event is determined as AB. For another example, among the physiological sign parameters of the target object, the apnea duration A and the blood oxygen saturation D meet the triggering conditions at the same time, the target physiological sign parameters are the two physiological sign parameters, and the event type of the respiratory event is determined as AD. For another example, among the physiological sign parameters of the target object, the blood oxygen saturation D meets the triggering condition, the target physiological sign parameter is the physiological sign parameter, and the event type of the respiratory event is determined as D.
具体的，基于不同的目标生理体征参数对应的不同报警事件类型来区分呼吸事件的类型。例如，A类型事件表示关于呼吸暂停持续时长的报警事件，例如呼吸暂停持续时长超过相应阈值；B类型事件表示关于心率和/或脉率的报警事件，例如心率和/或脉率低于相应阈值；D类型事件表示关于血氧饱和度的报警事件，例如血氧饱和度低于相应阈值；AB类型事件表示同时发生了A 类型事件、B类型事件；ABD事件表示同时发生了A类型事件、B类型事件、D类型事件；AB事件表示同时发生了A类型事件、B类型事件；AD事件表示同时发生了A类型事件、D类型事件，BD事件表示同时发生了D类型事件、B类型事件；等等。Specifically, the types of respiratory events are distinguished based on different types of alarm events corresponding to different target physiological sign parameters. For example, a type A event indicates an alarm event about the duration of apnea, such as the duration of the apnea exceeds a corresponding threshold; a type B event indicates an alarm event about the heart rate and / or pulse rate, such as the heart rate and / or pulse rate is below the corresponding threshold ; D-type events indicate alarm events related to blood oxygen saturation, for example, blood oxygen saturation is lower than the corresponding threshold; AB-type events indicate simultaneous occurrence of A-type events and B-type events; ABD events indicate simultaneous occurrence of A-type events, B Type event, type D event; AB event indicates that type A event and type B event occur simultaneously; AD event indicates that type A event and type D event occur simultaneously, and BD event indicates that type D event and type B event occur simultaneously; etc. Wait.
所确定出的呼吸事件的类型可以使用事件类型标记表示，所以在本申请中，事件类型标记与事件类型具有相同含义，事件类型标记可以简称为事件类型。The determined type of the respiratory event may be represented by an event type tag, so in this application, the event type tag has the same meaning as the event type, and the event type tag may be simply referred to as an event type.
事件类型可以认为是呼吸事件的一个属性。记录呼吸事件时，还可以记录呼吸事件的发生时间点。步骤1.1可以依据发生时间点，获得发生在预设时间段内的呼吸事件。预设时间段可以是从当前时间点开始的历史一段时间，如过去24小时内的呼吸事件。获得呼吸事件可能是一个，也可以是多个。The event type can be thought of as a property of a respiratory event. When recording a respiratory event, you can also record the point in time when the respiratory event occurred. Step 1.1 may obtain a breathing event occurring within a preset time period according to the occurrence time point. The preset time period may be a historical period from the current time point, such as a breathing event in the past 24 hours. Obtaining a breathing event may be one or more.
步骤1.3：在主监测界面中提供呼吸事件回顾界面，所述呼吸事件回顾界面包括事件显示区域。Step 1.3: A respiratory event review interface is provided in the main monitoring interface, and the respiratory event review interface includes an event display area.
其中，在一些实施例中，呼吸事件回顾界面可以作为主监测界面中的一个固定子区域，即呼吸事件回顾界面嵌入主监测界面，跟随主监测界面的显示而显示，跟随主监测界面的消失而消失。Among them, in some embodiments, the respiratory event review interface can be used as a fixed sub-area in the main monitoring interface, that is, the respiratory event review interface is embedded in the main monitoring interface, and is displayed following the display of the main monitoring interface and following the disappearance of the main monitoring interface. disappear.
在一些实施例中，呼吸事件回顾界面是可以打开及关闭的。具体地，响应于用户输入的触发指令，在主监测界面中弹出一呼吸事件回顾界面。弹出的呼吸事件回顾界面可以悬浮于主监测界面上，这种形式的呼吸事件回顾界面可以覆盖作为背景的主监测界面中的信息；或者呼吸事件回顾界面可以嵌入在主监测界面中，这种形式的呼吸事件回顾界面是弹出后嵌入在主监测界面中的，主监测界面中的其他信息可以消失，或者可以重新布局。也就是说，呼吸事件回顾界面可以是医疗设备显示器的整个显示界面，或者也可以是嵌入或浮在医疗设备显示器整个显示界面上的一个显示窗口。In some embodiments, the respiratory event review interface can be opened and closed. Specifically, in response to a trigger instruction input by the user, a breathing event review interface pops up in the main monitoring interface. The pop-up respiratory event review interface can be suspended on the main monitoring interface. This type of respiratory event review interface can cover the information in the main monitoring interface as the background; or the respiratory event review interface can be embedded in the main monitoring interface. This form The respiratory event review interface is embedded in the main monitoring interface after pop-up. Other information in the main monitoring interface can disappear or it can be re-arranged. That is, the respiratory event review interface may be the entire display interface of the medical device display, or may be a display window embedded or floating on the entire display interface of the medical device display.
呼吸事件回顾界面包括有事件显示区域，事件显示区域的位置属性、形状属性、显示属性、状态属性等均可调节。例如，事件显示区域的位置属性是指事件显示区域在主呼吸事件回顾界面的显示位置；事件显示区域的形状属性包括形状的样式、尺寸大小等，例如形状可以是各种，如矩形、圆形、心形等等；事件显示区域的显示属性是指显示区域的全部或部分的色彩、亮度、对比度等属性信息；事件显示区域的状态属性包括可见或不可见的属性、嵌入呼吸事件回顾界面或悬浮于呼吸事件回顾界面等等。The respiratory event review interface includes an event display area. The position, shape, display, and status attributes of the event display area can be adjusted. For example, the position attribute of the event display area refers to the display position of the event display area on the main respiratory event review interface; the shape attributes of the event display area include the shape style, size, etc. For example, the shape can be various, such as rectangle, circle , Heart shape, etc .; the display properties of the event display area refer to all or part of the display area's color, brightness, contrast and other property information; the status properties of the event display area include visible or invisible attributes, embedded in the respiratory event review interface, or Hover over the respiratory event review interface and much more.
在一些实施例中，事件显示区域可以跟随呼吸事件回顾界面的显示而显示，跟随呼吸事件回顾界面的消失而消失。或者，在一些实施例中，事件显示区域还具有独立的打开及关闭的控制按钮，当打开按钮被触发时，可切换事件显示区域的状态属性，使得事件显示区域显示在呼吸事件回顾界面的某个位置，当关闭按钮被触发时，可切换事件显示区域的状态属性，使得事件显示区域便从呼吸事件回顾界面中消失。需要说明的是，事件显示区域并不限定该区域在呼吸事件回顾界面中的位置是固定的，其可以是可活动的，例如可以根据触控操作的滑动轨迹调节事件显示区域的位置属性使得事件显示区域的显示可随着触控操作移动。In some embodiments, the event display area may be displayed following the display of the respiratory event review interface, and disappeared following the disappearance of the respiratory event review interface. Alternatively, in some embodiments, the event display area also has independent control buttons for opening and closing. When the open button is triggered, the state attributes of the event display area can be switched, so that the event display area is displayed on a respiratory event review interface. In this position, when the close button is triggered, the state attributes of the event display area can be switched, so that the event display area disappears from the breathing event review interface. It should be noted that the event display area does not limit the position of the area in the respiratory event review interface is fixed, it can be movable, for example, the position attribute of the event display area can be adjusted according to the sliding track of the touch operation to make the event The display of the display area can be moved with a touch operation.
步骤1.4：在所述事件显示区域输出显示基于所述预设时间段确定的时间轴，并基于所述事件类型标记对应所述时间轴显示所述呼吸事件。Step 1.4: Output and display a time axis determined based on the preset time period in the event display area, and display the breathing event corresponding to the time axis based on the event type mark.
其中，所获得的预设时间段内发生的呼吸事件，需要按照一种展示方式显示出来，以供医护人员查看。在一些实施例中，在事件显示区域生成具有时间轴的统计图表，在统计图表内显示呼吸事件。时间轴是与获得呼吸事件的预设时间段对应的，例如，获得的呼吸事件是过去24小时内发生的，则时间轴包含的时间长度为24小时。The respiratory events that occur during the obtained preset time period need to be displayed in a display manner for medical personnel to view. In some embodiments, a statistical graph with a time axis is generated in the event display area, and respiratory events are displayed within the statistical graph. The time axis corresponds to a preset time period for obtaining a breathing event. For example, if the obtained breathing event occurred within the past 24 hours, the time axis includes a time length of 24 hours.
在一具体实施例中，时间轴可以作为统计图表的横坐标，呼吸事件显示在横坐标对应的纵坐标处。显示呼吸事件具体是，在纵坐标处显示呼吸事件的事件类型标记。In a specific embodiment, the time axis may be used as the abscissa of the statistical chart, and the breathing event is displayed at the ordinate corresponding to the abscissa. Displaying a respiratory event is specifically displaying an event type mark of the respiratory event at the ordinate.
呼吸事件在具有事件类型标记属性的基础上，还可以具有发生时间点属性，获得呼吸事件时，可以一并得到呼吸事件的发生时间点。因此，基于所述事件类型标记对应所述时间轴显示所述呼吸事件的过程具体包括，获得呼吸事件的发生时间点以及呼吸事件的事件类型标记；在时间与事件类型标记的关系图表中，确定发生时间点对应的横坐标，并在横坐标对应的纵坐标位置处，提示事件类型标记。In addition to the event type tag attribute, the respiratory event can also have an occurrence time point attribute. When the respiratory event is obtained, the occurrence time point of the respiratory event can be obtained together. Therefore, the process of displaying the breathing event based on the event type mark corresponding to the time axis specifically includes obtaining the occurrence time point of the breathing event and the event type mark of the breathing event; in a relationship diagram of time and event type mark, determine The abscissa corresponding to the occurrence time point, and at the ordinate position corresponding to the abscissa, the event type mark is prompted.
通过上述对事件类型标记的说明可知，事件类型标记是由导致呼吸事件的生理体征参数确定的，因此，显示事件类型标记的同时，也可以显示导致呼吸事件的生理体征参数的数值。例如，在纵坐标位置处显示填充有背景颜色的区块。从一个时间点横坐标对应的哪些纵坐标上包含有区块，可以确定一条呼吸事件关联有哪些生理体征参数，进而确定出该呼吸事件的事件类型标记；同时，可以在区块内显示对应的触发该呼吸事件的生理体征参数的数值。It can be known from the above description of the event type mark that the event type mark is determined by the physiological sign parameters leading to the respiratory event. Therefore, while displaying the event type mark, the value of the physiological sign parameters leading to the respiratory event can also be displayed. For example, a block filled with a background color is displayed at the ordinate position. From which ordinates corresponding to the abscissa at a point in time contain blocks, it is possible to determine which physiological signs parameters are associated with a respiratory event, and then determine the event type mark of the respiratory event; at the same time, the corresponding The value of the physiological sign parameter that triggered the breathing event.
需要说明的是，本申请提及的时间轴，不局限于在显示界面中显示一时间坐标轴的方案，还包括其他能够提供时间信息的方案。例如，通过时间列表来提供时间信息的方案；或者即使在显示界面中不显示时间信息，但本领域普通技术人员能够通过所显示的内容获得时间信息的方案。It should be noted that the time axis mentioned in this application is not limited to the scheme of displaying a time axis on the display interface, and also includes other schemes capable of providing time information. For example, a scheme in which time information is provided through a time list; or a scheme in which a person of ordinary skill in the art can obtain time information through the displayed content even if the time information is not displayed in the display interface.
见图2A，其示出了事件显示区域的一个示例。如图2A所示，事件显示区域中包含有关系图表区域201，该区域内包含有时间与生理体征参数的关系图表，其中横坐标为时间轴，纵坐标包含三个生理体征参数，分别为呼吸暂停时长A、血氧饱和度D及心率B。需要说明的是，图2A中的斜线部分，可以填充有其他与呼吸相关的信息，也可以为空。See FIG. 2A, which shows an example of an event display area. As shown in FIG. 2A, the event display area includes a relationship chart area 201, which contains a relationship chart of time and physiological signs parameters, where the abscissa is the time axis and the ordinate contains three physiological sign parameters, respectively, breathing Pause duration A, blood oxygen saturation D, and heart rate B. It should be noted that the oblique line in FIG. 2A may be filled with other breathing-related information or may be empty.
从图示中可以看出，在横坐标的大概-18h(小时)、-15h、-12h、-8h、-4h处分别存在填充有背景色的区块，其中，-18h的横坐标点存在的三个区块分别对应的是生理体征参数A、B及D，-15h的横坐标点存在的三个区块分别对应的是生理体征参数A及D，-12h的横坐标点存在的三个区块分别对应的是生理体征参数B及D，-8h的横坐标点存在的三个区块分别对应的是生理体征参数D，-4h的横坐标点存在的三个区块分别对应的是生理体征参数A及B。当然，横坐标中的时间也可以表示为具体时间点，例如，从2018.7.20到2018.7.21的5个时间点：8:00、12:00、16:00、20:00、00:00、4:00。As can be seen from the figure, there are blocks filled with background colors at approximately -18h (hours), -15h, -12h, -8h, and -4h on the abscissa, among which -18h abscissa points The three blocks correspond to the physiological sign parameters A, B, and D, respectively. The three blocks that exist on the abscissa point of -15h correspond to the three sign blocks that exist on the abscissa point of -12h, respectively. Each block corresponds to the physical sign parameters B and D, and the three blocks existing at the abscissa point of -8h correspond to the three sign blocks at the abscissa point of the physiological sign parameter D and -4h respectively. Physiological signs parameters A and B. Of course, the time in the abscissa can also be expressed as a specific time point, for example, 5 time points from 2018.7.20 to 2018.7.21: 8:00, 12:00, 16:00, 20:00, 00:00 , 4:00.
从而可以确定出，图表中列出了历史24小时内发生的5条呼吸事件。在第18小时、15小时、12小时、8小时、4小时之前，发生的呼吸事件分别为ABD、AD、BD、D、及AB。It can be determined that the chart lists the five respiratory events that occurred in the past 24 hours. Before 18 hours, 15 hours, 12 hours, 8 hours, and 4 hours, the respiratory events that occurred were ABD, AD, BD, D, and AB, respectively.
由以上技术方案可知，本申请提供的呼吸事件的回顾显示方法，可以获得被监测对象在历史时间段内发生的呼吸事件，并确定呼吸事件的事件类型标记，进而基于事件类型标记，在呼吸事件回顾界面的事件显示区域，显示历史时间段内所发生的呼吸事件。医护人员可以通过查看事件显示区域，了解被监测对象的呼吸事件发生频率、发生次数、严重程度等相关信息，进而了解被监测对象的呼吸状况。It can be known from the above technical solutions that the retrospective display method for respiratory events provided by the present application can obtain the respiratory events that occurred in the monitored object in the historical time period, and determine the event type markers of the respiratory events. Based on the event type markers, The event display area of the review interface displays the breathing events that occurred during the historical period. Medical personnel can look at the event display area to understand the frequency, frequency, severity and other related information of the respiratory events of the monitored subject, and then understand the respiratory status of the monitored subject.
在一些实施例中，由于呼吸事件可以包含呼吸暂停事件，也可以包含呼吸氧合事件，这两类事件表示呼吸问题的严重程度不同，因此为了明确地提示医护人员发生哪类的呼吸事件，可以通过不同的显示样式对不同类型的呼吸事件进行区分。In some embodiments, since the respiratory event may include an apnea event or a respiratory oxygenation event, the two types of events indicate that the severity of the breathing problem is different, so in order to clearly indicate which type of respiratory event the medical staff has occurred, you can Different types of breathing events are distinguished by different display styles.
具体地，采用第一显示样式显示所述呼吸暂停事件，采用区别于第一显示样式的第二显示式显示所述呼吸氧合事件。在一些实施例中，显示样式可以具体为呼吸事件的区块颜色。例如，呼吸暂停事件的区块背景颜色，相较于呼吸氧合事件的区块背景颜色更深。Specifically, the apnea event is displayed using a first display style, and the respiratory oxygenation event is displayed using a second display style different from the first display style. In some embodiments, the display style may be specifically a block color of a breathing event. For example, the block background color of an apnea event is darker than the block background color of a respiratory oxygenation event.
以图2A中的五条呼吸事件为例，根据上述对呼吸事件的定义可知，呼吸暂停事件可以包括呼吸事件ABD、AD及AB，呼吸氧合事件可以包括呼吸事件BD及D。因此，前三个呼吸事件的区块背景颜色可以深于后两个呼吸事件。更进一步地，呼吸氧合事件中的某些呼吸事件可能被医护人员标记为非统计呼吸事件，该呼吸事件并不纳入到对呼吸事件的统计中。因此，呼吸事件可以在包括呼吸暂停事件、呼吸氧合事件的基础上，还可以包括非统计呼吸事件，三类呼吸事件使用三种不同的样式进行显示。如图2A所示，非统计呼吸事件为呼吸事件D，该呼吸事件使用白色进行显示。Taking the five respiratory events in FIG. 2A as an example, according to the foregoing definition of the respiratory events, it can be known that the apnea events may include respiratory events ABD, AD, and AB, and the respiratory oxygenation events may include respiratory events BD and D. Therefore, the block background color of the first three breathing events can be darker than the last two breathing events. Furthermore, some respiratory events in respiratory oxygenation events may be marked as non-statistical respiratory events by medical personnel, and the respiratory events are not included in the statistics of respiratory events. Therefore, respiratory events can include apnea events, respiratory oxygenation events, and non-statistical respiratory events. Three types of respiratory events are displayed using three different styles. As shown in FIG. 2A, the non-statistical respiratory event is respiratory event D, which is displayed in white.
需要说明的是，提示呼吸事件的区块可以并不局限于方形，还可以是其他形状，进一步提示方式也并不局限于区块，还可以是其他形式如图标、字符等。另外，区别不同分类的呼吸事件的方式，也并不局限于区块的背景颜色，在使用字符表示生理体征参数的情况下，也可以是字符粗细、是否斜体、是否加下划线、是否添加标识符号等等。It should be noted that the block for prompting a breathing event may not be limited to a square, but may also have other shapes. Further prompting methods are not limited to the block, and may also be in other forms such as icons and characters. In addition, the way to distinguish different types of respiratory events is not limited to the background color of the block. In the case of using characters to represent the physical sign parameters, it can also be the character thickness, whether it is italic, whether to underline, or whether to add a logo and many more.
在实际应用中，目标对象若发生呼吸事件，监测设备记录呼吸事件时，还可以一并记录呼吸事件关联的生理体征参数的关注数据。关注数据是医护人员比较关注的与呼吸事件相关的信息，为了便于理解，首先对关注数据进行说明。In practical applications, if a target subject has a respiratory event, the monitoring device may also record the attention data of the physiological sign parameters associated with the respiratory event when recording the respiratory event. Attention data is the information related to respiratory events that medical personnel are more concerned about. To facilitate understanding, the attention data is first explained.
关注数据用于表示呼吸事件的严重情况。需要说明的是，关注数据对呼吸事件严重程度的反映是一种客观的反映，符合人们的客观认知标准。例如，在呼吸事件中，如果目标对象的心率越低，客观认知认为呼吸事件越严重，因此关注数据可以包括事件片段中心率的最低值。又如，在呼吸事件中，如果目标对象的血氧饱和度值越低，在客观认知上也认为该呼吸事件越严重，因此关注数据可以包括事件片段中血氧饱和度值的最低值。再如，在呼吸事件中，如果目标对象的呼吸暂停时长越长，在客观认知上也认为该呼吸事件越严重，因此关注数据可以包括事件片段中的呼吸暂停时长的最大值。Attention data is used to indicate the severity of a respiratory event. It should be noted that the reflection of the attention data on the severity of respiratory events is an objective reflection and meets people's objective cognitive standards. For example, in a respiratory event, if the target's heart rate is lower, objective recognition believes that the respiratory event is more serious, so the attention data may include the lowest value of the center rate of the event segment. For another example, in a respiratory event, if the target patient's blood oxygen saturation value is lower, it is also considered objectively that the respiratory event is more serious, so the data of interest may include the lowest value of blood oxygen saturation value in the event segment. As another example, in an apnea event, if the apnea duration of the target object is longer, it is also considered objectively that the apnea duration is more serious, so the attention data may include the maximum value of the apnea duration in the event segment.
在一些实施例中，关注数据是呼吸事件关联的生理体征参数的最值。In some embodiments, the data of interest is the highest value of a physiological sign parameter associated with a respiratory event.
为了得到各项生理体征参数的最值，需要设置统计时长，在这个有限时长内所获得的数值是有限的，在有限数据中才可以确定出生理体征参数的最值。 统计时长的长度可以是预先设置的，如4分钟等。需要说明的是，包括呼吸暂停事件发生时间点的统计时长这个长度的一段时间，可以称为监测时间区间或事件片段。In order to obtain the maximum value of each physiological sign parameter, it is necessary to set the statistical time. The value obtained within this limited time is limited. Only in the limited data can the maximum value of the physiological sign parameter be determined. The length of the statistics duration can be preset, such as 4 minutes. It should be noted that a period of time including the statistical length of the apnea event occurrence time point may be referred to as a monitoring time interval or an event segment.
在确定呼吸暂停时长的最大值时，将事件片段内的各个呼吸暂停时长进行比较，从而确定出最大值。同理，能够确定出血氧饱和度值的最低值、心率的最低值及脉率的最低值。在另一些实施例中，关注数据针对的生理体征参数并不局限于上述几种，还可以是其他如灌注指数。When determining the maximum value of the apnea duration, the respective apnea durations within the event segment are compared to determine the maximum value. In the same way, it is possible to determine the minimum value of the oxygen saturation value, the minimum value of the heart rate, and the minimum value of the pulse rate. In other embodiments, the physiological sign parameters targeted by the data of interest are not limited to the above, and may also be other such as perfusion index.
确定出生理体征参数的关注数据后，将关注数据显示在呼吸事件所在时间轴的相对位置处。具体地，根据呼吸事件的发生时间点，确定该发生时间点在时间轴上的横坐标位置，在横坐标对应的生理体征参数的纵坐标位置处，提示生理体征参数的关注数据。After determining the attention data of the physiological sign parameters, the attention data is displayed at the relative position of the time axis where the respiratory event is located. Specifically, the abscissa position of the occurrence time point on the time axis is determined according to the occurrence time point of the respiratory event, and the attention data of the physiological sign parameter is prompted at the ordinate position of the physiological sign parameter corresponding to the abscissa.
生理体征参数的关注数据可以与呼吸事件的事件类型标记关联显示，例如，事件类型标记以区块表示，生理体征参数的关注数据作为数值填充在区块内。The attention data of the physiological sign parameters can be displayed in association with the event type mark of the respiratory event. For example, the event type mark is represented by a block, and the attention data of the physiological sign parameter is filled in the block as a value.
如图2A所示，呼吸事件ABD的关注数据分别为，呼吸暂停时长的最大时长23s(秒)、血氧饱和度的最低值60％、及心率最低值78bpm(beat per minute，每分钟节拍数)，这些关注数据分别填充在对应的事件类型标记A、B及D的区块内。呼吸事件AD的关注数据分别为，呼吸暂停时长的最大时长12s、血氧饱和度的最低值68％，这些关注数据分别填充在对应的事件类型标记A及D的区块内。呼吸事件BD的关注数据分别为，血氧饱和度的最低值77％、及心率最低值70bpm，这些关注数据分别填充在对应的事件类型标记B及D的区块内。呼吸事件D的关注数据为，血氧饱和度的最低值64％，该关注数据填充在对应的事件类型标记D的区块内。呼吸事件AB的关注数据分别为，呼吸暂停时长的最大时长23s、及心率最低值82bpm，这些关注数据分别填充在对应的事件类型标记A及B的区块内。文中有些描述中，血氧饱和度及心率的数值并未添加单位，但需要说明的是，血氧饱和度的数值单位为％，心率的数值单位为bpm。As shown in FIG. 2A, the attention data of the respiratory event ABD are: the maximum duration of apnea duration is 23s (seconds), the minimum value of blood oxygen saturation is 60%, and the minimum value of heart rate is 78bpm (beat per minute, beats per minute) ), These attention data are respectively filled in the corresponding event type marks A, B and D blocks. The attention data of the respiratory event AD are respectively the maximum duration of apnea duration 12s and the lowest value of blood oxygen saturation 68%. These attention data are respectively filled in the corresponding event type markers A and D blocks. The attention data of the respiratory event BD are the lowest value of blood oxygen saturation 77% and the lowest value of heart rate 70 bpm. These attention data are respectively filled in the corresponding event type marks B and D. The attention data of the respiratory event D is the lowest value of blood oxygen saturation 64%, and the attention data is filled in the corresponding event type mark D block. The attention data of the respiratory event AB are the maximum duration of apnea duration of 23s and the minimum heart rate of 82bpm. These attention data are respectively filled in the corresponding event type marks A and B blocks. In some descriptions in the text, the units of blood oxygen saturation and heart rate are not added, but it should be noted that the unit of blood oxygen saturation is% and the unit of heart rate is bpm.
与不同类型呼吸事件的区分方式同理，可以对不同类型呼吸事件的关注数据通过显示样式区分。例如，显示样式可以包括但不局限于字体颜色、字体粗细、是否斜体、是否加下划线、是否添加标记符号等等。In the same way as different types of respiratory events, the attention data of different types of respiratory events can be distinguished through display styles. For example, the display style may include, but is not limited to, font color, font thickness, whether it is italic, whether to underline, whether to add a marker symbol, and the like.
由以上技术方案可知，可以在统计图表中显示呼吸事件时，同时显示呼吸 事件体征状态参数的关注数据。医护人员除了可以了解到历史一段时间内呼吸事件的发生时间点，发生频率等信息，还可以了解每条呼吸事件发生时，各项生理体征参数的最差状态，从而了解该呼吸事件的严重程度。It can be known from the above technical solution that when the respiratory event is displayed in the statistical chart, the attention data of the respiratory event sign state parameters can be displayed at the same time. In addition to knowing the occurrence time and frequency of respiratory events in a historical period of time, medical personnel can also understand the worst state of each physiological sign parameter when each respiratory event occurs, so as to understand the severity of the respiratory event .
为用户显示呼吸事件的统计结果后，用户可以选中某个呼吸事件，来查看该呼吸事件的详细信息。After displaying the statistical results of respiratory events for the user, the user can select a respiratory event to view the detailed information of the respiratory event.
具体地，响应对所述呼吸事件回顾界面所显示的呼吸事件的选中操作，获得被选中的呼吸事件关联的生理体征参数；在所述呼吸事件回顾界面的单事件展示区域，至少显示所述被选中的呼吸事件的生理体征参数的波形图和/或关注数据。Specifically, in response to a selection operation of a respiratory event displayed on the respiratory event review interface, physiological parameter parameters associated with the selected respiratory event are obtained; at least a single event display area in the respiratory event review interface is displayed.

基于用户的选择指令，可以在单事件展示区域中显示用户所选择的呼吸事件关联的生理体征参数的相关信息。相关信息可以包括生理体征参数的波形图，如被选中的呼吸事件的呼吸波形图、血氧饱和度趋势图、心率趋势图、脉率趋势图中的一个或多个。或者，相关信息可以包括生理体征参数的关注数据，如包括所述被选中的呼吸事件中呼吸暂停持续时长最大值、血氧饱和度最低值、心率最低值、脉率最低值中的一个或多个。或者，相关信息可以包括以上两种内容。Based on the user's selection instruction, the related information of the physiological sign parameters associated with the respiratory event selected by the user can be displayed in the single event display area. The related information may include one or more waveform diagrams of physiological sign parameters, such as a respiratory waveform diagram of a selected respiratory event, a blood oxygen saturation trend chart, a heart rate trend chart, and a pulse rate trend chart. Alternatively, the related information may include attention data of physiological sign parameters, such as including one or more of the maximum duration of apnea duration, the lowest value of blood oxygen saturation, the lowest value of heart rate, and the lowest value of pulse rate in the selected breathing event. Each. Alternatively, the related information may include the above two contents.
见图2B，其示出了呼吸事件回顾界面的另一示例。如图2B所示，呼吸事件回顾界面在包含关系图表区域211的基础上，还可以包含单事件展示区域212。当医护人员需要查看某条呼吸事件的详细信息时，可以选择该呼吸事件。See Figure 2B, which illustrates another example of a respiratory event review interface. As shown in FIG. 2B, the respiratory event review interface may include a single event display area 212 on the basis of a relationship chart area 211. When a medical staff needs to view the details of a respiratory event, he or she can select the respiratory event.
假设医护人员选择第18h之前发生的呼吸事件，如图2B所示，被选择的呼吸事件由实线框选中，则在单事件展示区域212中，显示该呼吸事件的呼吸(Resp)波形图、心率(btbHR)趋势图、以及血氧饱和度(SpO2)趋势图，以及显示呼吸暂停(apnea)时长最大值、心率最低值及血氧饱和度最低值。如图2B所示，趋势图中还可以使用虚线表示生理体征参数的报警阈值，如心率的报警阈值为100，血氧饱和度的报警阈值为80。Assume that the medical staff selects a respiratory event that occurred before the 18th hour, as shown in FIG. 2B, and the selected respiratory event is selected by a solid line frame. In the single event display area 212, the respiratory waveform (Resp) of the respiratory event is displayed, Heart rate (btbHR) trend graph, and blood oxygen saturation (SpO2) trend graph, and display the maximum value of apnea duration, the lowest heart rate and the lowest value of blood oxygen saturation. As shown in FIG. 2B, the dash line can also be used to indicate the alarm threshold of physiological signs parameters. For example, the alarm threshold of heart rate is 100, and the alarm threshold of blood oxygen saturation is 80.
其中心率最低值也对应于心动过缓(bradycardia)事件的最低值，血氧饱和度最低值对应于低血氧饱和度(desaturation)事件的极限值。如图2B所示，趋势图为4分钟之内的一个趋势图。另外，呼吸波形图可以是阻抗呼吸压缩波形图。The lowest value of its central rate also corresponds to the lowest value of bradycardia events, and the lowest value of blood oxygen saturation corresponds to the limit value of hypoxia events. As shown in FIG. 2B, the trend chart is a trend chart within 4 minutes. In addition, the breathing waveform chart may be an impedance breathing compression waveform chart.
进一步地，除了可以显示呼吸事件的生理体征参数的相关信息，还可以显示呼吸事件的关联信息。关联信息可以是医护人员通过以下标记界面输入的信息，该关联信息作为呼吸事件的一个属性保存。关联信息是呼吸事件发生时，目标对象的一些外在情况，这些情况可以帮助医护人员了解目标对象所发生的呼吸事件的严重情况。Further, in addition to the information related to the physiological sign parameters of the respiratory event, the related information of the respiratory event can also be displayed. The related information may be information input by a medical staff through the following markup interface, and the related information is saved as an attribute of a respiratory event. The related information is some external conditions of the target object when the respiratory event occurs. These conditions can help the medical staff understand the serious situation of the respiratory event that the target object occurs.
例如，关联信息可以包括皮肤颜色、刺激程度、自定义；其中，皮肤颜色可能是：红润、灰白、绀紫、斑点、黄疸中的任意一项；刺激程度可能是：强、中、弱、无中的任意一项；自定义可以是：机械通气、喂养中的任意一项。For example, the related information may include skin color, irritation degree, and custom. Among them, the skin color may be any one of: ruddy, off-white, purplish purple, spots, jaundice; the irritation degree may be: strong, medium, weak, none Any one of them; custom can be any one of mechanical ventilation and feeding.
医护人员可以在呼吸事件发生时进行临床观察，并根据临床观察记录关联信息。在显示时，将所记录的关联信息显示在单事件展示区域内。如图2B所示，所显示的关联信息包括，皮肤颜色(skin color)为粉红(pink)，刺激程度(stimulation)为弱(mild)。其中刺激程度表示的是医护人员为了解除病人呼吸暂停状态，施予病人的刺激动作。Medical personnel can perform clinical observations when respiratory events occur, and record related information based on clinical observations. When displaying, the recorded related information is displayed in a single event display area. As shown in FIG. 2B, the displayed related information includes that the skin color is pink and the stimulation is mild. The stimulus level indicates the stimulus action given by the medical staff to relieve the patient's apnea state.
另外，相关信息还可以包括与呼吸状态相关的一些其他生理体征参数，如图2B所示，还可以包括无创血压(NIBP)为115/90(101)。再者，相关信息还可以包括相关信息的记录时间点，如图2B所示，该条相关信息的记录时间点为09:32。再者，相关信息还可以包括被选中的呼吸事件的事件类型及发生时间点，如图2B所示，被选中的呼吸事件的事件类型为ABD，发生时间点为9:30。In addition, the related information may also include some other physiological signs parameters related to the breathing state, as shown in FIG. 2B, and may also include a non-invasive blood pressure (NIBP) of 115/90 (101). Furthermore, the related information may also include a recording time point of the related information. As shown in FIG. 2B, the recording time point of the piece of related information is 09:32. Furthermore, the related information may also include the event type and occurrence time point of the selected breathing event, as shown in FIG. 2B, the event type of the selected breathing event is ABD, and the occurrence time point is 9:30.
需要说明的是，如果在关系图表区域211切换选中的呼吸事件，则单事件展示区域212会切换为其他呼吸事件的生理体征参数的相关信息及关联信息。另外，关系图表区域211及单事件展示区域212之间的位置关系并不局限于上下，还可以是左右。It should be noted that if the selected breathing event is switched in the relationship chart area 211, the single event display area 212 will be switched to the related information and related information of the physical sign parameters of other breathing events. In addition, the positional relationship between the relationship chart area 211 and the single event display area 212 is not limited to the top and bottom, and may be left and right.
除了图2A使用区块表示呼吸事件的生理体征参数外，本申请还提供了使用带有标记点的短线进行表示的方式。In addition to the use of blocks in FIG. 2A to represent the physiological sign parameters of respiratory events, the present application also provides a manner of using short lines with marked points for representation.
见图2C，其示出了呼吸事件回顾界面的又一示例。如图2C所示，呼吸事件回顾界面中包含有关系图表区域221，该区域内包含有时间与生理体征参数的关系图表，其中横坐标为时间轴，纵坐标包含三个生理体征参数，分别为心率(HR)、血氧饱和度(SpO2)、以及呼吸暂停(Apnea)。See FIG. 2C, which illustrates yet another example of a respiratory event review interface. As shown in FIG. 2C, the respiratory event review interface includes a relationship chart area 221, which contains a relationship chart between time and physiological signs parameters, where the abscissa is the time axis and the ordinate contains three physiological sign parameters, which are Heart rate (HR), blood oxygen saturation (SpO2), and apnea (Apnea).
每个生理体征参数具有各自对应的阈值，如图2C所示，阈值可以使用虚线表示。例如，心率100bpm是阈值标尺，当心率低于100则触发呼吸事件， 图示中的80bpm仅仅是标尺刻度一部分，为了便于阅读具体心率最低值；SpO2的80％是阈值标尺，当SpO2低于80％则触发呼吸事件，图示中的50％仅仅是标尺刻度的一部分，为了便于阅读具体SpO2最低值；呼吸暂停的10s是阈值标尺，当呼吸暂停持续时间超过10s，则触发呼吸事件。Each physiological sign parameter has a corresponding threshold, as shown in FIG. 2C, and the threshold can be represented by a dashed line. For example, heart rate 100bpm is a threshold scale. When the heart rate is lower than 100, a breathing event is triggered. 80bpm in the figure is only a part of the scale scale. In order to facilitate reading of the specific heart rate, 80% of SpO2 is the threshold scale. % Will trigger a breathing event, and 50% in the figure is only a part of the scale. In order to facilitate reading the specific SpO2 minimum value; 10s of apnea is a threshold scale. When the duration of apnea exceeds 10s, a breathing event is triggered.
如图2C所示，每个时间点上的一组短线构成一个呼吸事件，具体地，呼吸事件中如果包括心率这个生理体征参数，则从心率这个区域的顶端向下延伸出一条短线，血氧饱和度及呼吸暂停对应的短线同理。每条短线的顶端包含圆点，圆点所在的位置对应的纵坐标数值为该呼吸事件的关注数据。需要说明的是，带有标记点的短线可以替换为，只有短线或只有标记点。标记点除了可以是圆点，还可以是三角形、方框等各种形状。As shown in FIG. 2C, a set of short lines at each time point constitutes a breathing event. Specifically, if the breathing event includes a physiological sign parameter of heart rate, a short line extends downward from the top of the heart rate region, blood oxygen The same goes for the short-term corresponding to saturation and apnea. The top of each short line contains a dot, and the ordinate value corresponding to the position of the dot is the attention data of the respiratory event. It should be noted that the short lines with marked points can be replaced with only short lines or only marked points. In addition to the dots, the marked points can also be in various shapes such as triangles and boxes.
在一种实现方式中，关注数据可以直接显示在圆点附近的位置。在另一种实现方式中，用户可以选择某条具体的呼吸事件，在单事件展示区域显示生理体征参数的关注数据。In one implementation, the attention data may be directly displayed at a position near the dot. In another implementation manner, the user may select a specific respiratory event, and display the attention data of the physiological sign parameters in the single event display area.
见图2D，其示出了呼吸事件回顾界面的又一示例。如图2D所示，呼吸事件回顾界面中包含关系图表区域231及单事件展示区域232。关系图表区域231包含有七个由短线组表示的呼吸事件。假设从左至右第三个呼吸事件被选中，则在单事件展示区域232中，显示该呼吸事件的生理体征参数的关注数据，即心率(Bradycardia)最低值为60且低于设置的阈值持续14s(秒)；血氧饱和度(Desaturation)最低值为78；呼吸暂停(Apnea)时长最大值为23秒。See Fig. 2D, which illustrates yet another example of a respiratory event review interface. As shown in FIG. 2D, the respiratory event review interface includes a relationship chart area 231 and a single event display area 232. The relationship chart area 231 contains seven breathing events represented by a short-line group. Assuming that the third breathing event is selected from left to right, in the single event display area 232, the attention data of the physiological sign parameters of the breathing event is displayed, that is, the minimum value of the heart rate (Bradycardia) is 60 and continues to be lower than the set threshold. 14s (seconds); the minimum value of blood oxygen saturation (Desaturation) is 78; the maximum value of apnea duration is 23 seconds.
需要说明的是，为了进行明显的提示，生理体征参数的关注数据可以使用具有突出效果的预设显示样式，如可以将关注数据用底色反色显示，又如可以使用区别颜色进行区分显示。It should be noted that, for obvious indication, the attention data of the physiological sign parameters may use a preset display style with a prominent effect. For example, the attention data may be displayed in a reverse color of the background color, and the distinguished color may be used for the distinguished display.
单事件展示区域232包括关系图标区域231上侧的关联信息以及右侧的最值区域。The single event display area 232 includes the related information on the upper side of the relationship icon area 231 and the most value area on the right side.
另外，如图2D所示，在被选中的呼吸事件的短线旁边，还可以显示发生时间点9:30。In addition, as shown in FIG. 2D, next to the short line of the selected breathing event, the occurrence time point 9:30 can also be displayed.
根据上述图2B及图2D的说明可知，针对所选中的呼吸事件，可以在呼吸事件回顾界面的单事件展示区域，显示被选中的呼吸事件所关联的生理体征参数，如生理体征参数的趋势图和/或生理体征参数的最值。进一步，还可以显示医护人员录入的呼吸事件的关联信息。According to the above description of FIG. 2B and FIG. 2D, it can be known that, for the selected breathing event, the physiological event parameters associated with the selected breathing event can be displayed in the single event display area of the breathing event review interface, such as a trend chart of the physiological sign parameters. And / or the maximum value of a physiological sign parameter. Further, the related information of the respiratory events entered by the medical staff can also be displayed.
在实际应用中，对呼吸事件的分析还可以包括，按照事件类型标记统计在 预设时间段内呼吸事件的发生次数。In practical applications, the analysis of the respiratory event may further include counting the number of occurrences of the respiratory event within a preset time period according to the event type mark.
需要说明的是，统计时除了判断呼吸事件是否在预设时间段内，还可以判断呼吸事件是否存在不纳入统计的标记，如果某呼吸事件发生时间点在预设时间段内，但该呼吸事件具有不纳入统计的标记，则可以并不统计该呼吸事件。It should be noted that in addition to determining whether a respiratory event is within a preset time period, it is also possible to determine whether there is a marker that is not included in the statistics of a respiratory event. If a respiratory event occurs within a preset time period, but the respiratory event With a marker not included in the statistics, the respiratory event may not be counted.
这样统计的理由是，有些呼吸事件虽然被设备判断为呼吸事件，但医护人员对目标对象的情况进行观察后发现，该呼吸事件的发生可能是由于目标对象健康状况之外的原因导致的，如医护人员对婴儿的喂养操作导致了该呼吸事件。由于统计结果可以作为医护人员评判目标对象呼吸状态的依据，这些意外原因导致的呼吸事件如果纳入统计，会影响评判结果。因此，可以由医护人员对呼吸事件进行标记，标记结果可以作为呼吸事件的一个属性存储。在统计时根据该属性决定呼吸事件是否纳入统计。The reason for this statistics is that although some respiratory events are judged to be respiratory events by the device, medical personnel observe the situation of the target object and find that the occurrence of the respiratory event may be caused by reasons other than the health status of the target object, such as The breathing incident was caused by the feeding operation of the baby by the medical staff. Because the statistical results can be used as a basis for judging the breathing status of the target object by medical personnel, if the respiratory events caused by these unexpected causes are included in the statistics, the judgment results will be affected. Therefore, respiratory events can be labeled by medical personnel, and the labeled results can be stored as an attribute of the respiratory events. During the statistics, it is determined whether the respiratory event is included in the statistics according to this attribute.
在主监测界面中提供次数统计区域，呼吸事件的发生次数，可以包含在次数统计区域中进行显示。次数统计区域在主监测界面中的显示方式可以参见呼吸事件回顾界面，此处并不赘述。另外，次数统计区域可以作为主监测界面中的一个区域，也可以作为呼吸事件回顾界面中的一个区域。The number of times statistics area is provided in the main monitoring interface, and the number of occurrences of respiratory events can be included in the number of times statistics area for display. For the display method of the frequency statistics area in the main monitoring interface, refer to the respiratory event review interface, which is not repeated here. In addition, the frequency statistics area can be used as an area in the main monitoring interface or as a area in the respiratory event review interface.
见图2E，其示出了呼吸事件回顾界面的又一示例。See Figure 2E, which illustrates yet another example of a respiratory event review interface.
如图2E所示，呼吸事件回顾界面在包含关系图表区域241、单事件展示区域242的基础上，还可以包括次数统计区域243。次数统计区域243内显示有：24小时总共发生10次呼吸事件，这些呼吸事件分为八种类型，其中：呼吸事件ABD发生1次，呼吸事件AB发生1次，呼吸事件AD发生1次，呼吸事件A20发生1次，呼吸事件A10发生3次，呼吸事件BD发生1次，呼吸事件B发生1次，呼吸事件D发生1次。As shown in FIG. 2E, the respiratory event review interface may include a relationship chart area 241 and a single event display area 242, and may further include a frequency count area 243. The count statistics area 243 shows that there are a total of 10 respiratory events in 24 hours. These respiratory events are divided into eight types, of which: respiratory event ABD occurs once, respiratory event AB occurs once, respiratory event AD occurs once, breathing Event A20 occurred once, respiratory event A10 occurred 3 times, respiratory event BD occurred 1 time, respiratory event B occurred 1 time, and respiratory event D occurred 1 time.
其中，呼吸事件A20表示呼吸暂停时长报警阈值为20秒，发生该呼吸事件则表示目标对象的呼吸暂停时长超过20秒；呼吸事件A10表示呼吸暂停时长报警阈值为10秒，发生该呼吸事件则表示目标对象的呼吸暂停时长超过10秒。Among them, the respiratory event A20 indicates that the apnea duration alarm threshold is 20 seconds, and the occurrence of this respiratory event indicates that the target subject's apnea duration exceeds 20 seconds; the respiratory event A10 indicates that the apnea duration alarm threshold is 10 seconds, and the occurrence of this respiratory event indicates that The target's apnea is longer than 10 seconds.
需要说明的是，与关系图表区域内呼吸事件的显示方式相同，可以按照呼吸事件的分类进行区分显示。另外，次数统计区域可以并不与其他的区域共同显示，而是单独显示在呼吸事件回顾界面中。It should be noted that, in the same manner as the display of respiratory events in the relationship chart area, the respiratory events can be classified and displayed according to the classification. In addition, the frequency statistics area may not be displayed together with other areas, but may be separately displayed in the respiratory event review interface.
在临床观察中发现，某一些生理体征参数的统计情况对于分析目标对象的 呼吸状态具有一定的指导意义。这些生理体征参数可以是本文中提及的任意一种。因此，可以在主监测界面中显示对该生理体征参数的统计结果。It is found in clinical observation that the statistics of certain physiological signs parameters have certain guiding significance for analyzing the breathing status of the target object. These physiological sign parameters may be any of those mentioned herein. Therefore, the statistical results of the physiological sign parameters can be displayed in the main monitoring interface.
具体地，获得所述目标对象的至少一种生理体征参数在所述预设时间长度内的历史值；基于至少一个参数分区对所述历史值进行分布统计，并确定对应于所述参数分区的分布统计结果；所述参数分区表示所述生理体征参数的数值区间；以及在所述主监测界面提供分段统计区域，并在所述分段统计区域显示所述分布统计结果。Specifically, a historical value of at least one physiological sign parameter of the target object within the preset time length is obtained; distribution statistics are performed on the historical value based on at least one parameter partition, and a parameter corresponding to the parameter partition is determined. Distribution statistical results; the parameter partitions indicate numerical intervals of the physiological sign parameters; and a segmented statistical area is provided on the main monitoring interface, and the distribution statistical results are displayed in the segmented statistical area.
其中，分布统计结果为：所述生理体征参数在预设时间长度内的历史值中，分别落入所述参数分区的数量或者数量比值。The statistical result of the distribution is that the historical values of the physiological sign parameters within a preset time length fall into the number of the parameter partitions or the number ratio, respectively.
统计结果可以通过文字的形式展示，或者为了方便查看，以形象的分布统计图表的形式展示。因此，基于所述参数分区和所述分布统计结果，在主监测界面中生成分布统计图表。在一些实施例中，分布统计图表为分别以所述参数分区和所述分布统计结果为两个坐标轴的直方图。例如，将参数分布作为直方图的横坐标，将分布统计结果作为直方图的纵坐标。The statistical results can be displayed in the form of text, or for the convenience of viewing, it is displayed in the form of statistical distribution chart. Therefore, based on the parameter partition and the distribution statistical result, a distribution statistical chart is generated in the main monitoring interface. In some embodiments, the distribution statistical chart is a histogram with the parameter partition and the distribution statistical result as two coordinate axes, respectively. For example, the parameter distribution is taken as the abscissa of the histogram, and the distribution statistical result is taken as the ordinate of the histogram.
需要说明的是，分段统计区域中所显示的生理体征参数的个数、生理体征参数的类型、历史值所对应的预设时间长度中的任意一个或多个，是可以由用户设置的。具体地，可以在分段统计区域中提供选择窗口，用户可以通过该选择窗口输入选择指令，选择指令表示对用户所关注的目标生理体征参数，及其历史值所对应的预设时间长度的选择。进而，响应用户输入的选择指令，在分段统计区域中显示用户所选择的目标生理体征参数的历史值的分布统计结果。当然，用户输入选择指令的方式并不局限于界面提供的虚拟选择窗口，还可以在监护仪中提供实体按钮，以供用户进行选择设置。It should be noted that any one or more of the number of physiological sign parameters displayed in the segmented statistical area, the type of the physiological sign parameters, and the preset time length corresponding to the historical value can be set by the user. Specifically, a selection window may be provided in the segmented statistical area, and the user may enter a selection instruction through the selection window, and the selection instruction indicates selection of a target physiological sign parameter of interest to the user and a preset time length corresponding to the historical value thereof. . Further, in response to the selection instruction input by the user, the statistical results of the distribution of the historical values of the target physiological sign parameters selected by the user are displayed in the segmented statistical area. Of course, the manner in which the user enters the selection instruction is not limited to the virtual selection window provided by the interface, and a physical button can also be provided in the monitor for the user to make selection settings.
本申请实施例假设用户所选择的目标生理体征参数为血氧饱和度，以下以该生理体征参数为例进行说明。The embodiment of the present application assumes that the target physiological sign parameter selected by the user is blood oxygen saturation, and the physiological sign parameter is taken as an example for description below.
获得目标对象在预设时间段内血氧饱和度的各个历史值；确定各个历史值所归属的血氧饱和度分区；统计每个血氧饱和度分区内的历史值数量与历史值总量之间的比值，并显示比值。其中，一个血氧饱和度分区为[0-100％]之间的部分区间，多个血氧饱和度分区组合起来为[0-100％]的整个区间。Obtain each historical value of blood oxygen saturation of the target object within a preset time period; determine the blood oxygen saturation zone to which each historical value belongs; count the total number of historical values and the total value of historical values in each blood oxygen saturation zone Ratio and display the ratio. Among them, one blood oxygen saturation partition is a partial interval between [0-100%], and a plurality of blood oxygen saturation partitions are combined into an entire interval [0-100%].
见图2F，其示出了呼吸事件回顾显示方法的又一示例。如图2F所示，呼吸事件回顾界面中在包含关系图表区域251、单事件展示区域252、次数统计区域253的基础上，还可以包括分段统计区域254。分段统计区域254中包含 有四个血氧饱和度分区，分别为[0-80％]、[81％]-90％]、[91％]-95％]、[96％]-100％]。目标对象在过去24小时(h)的血氧统计(SpO2Statistic)为：血氧饱和度值小于80％的数量占总量的5％，血氧饱和度值大于81％小于90％的数量占总量的15％，血氧饱和度值大于91％小于95％的数量占总量的70％，血氧饱和度值大于96％小于100％的数量占总量的10％。See FIG. 2F, which illustrates yet another example of a respiratory event review display method. As shown in FIG. 2F, the respiratory event review interface may further include a segmented statistics area 254 on the basis of a relationship chart area 251, a single event display area 252, and a frequency statistics area 253. The segmented statistical area 254 contains four blood oxygen saturation zones, which are [0-80%], [81%]-90%], [91%]-95%], [96%]-100% ]. SpO2Statistic of the target object in the past 24 hours (SpO2Statistic): The number of blood oxygen saturation values less than 80% accounts for 5% of the total, and the number of blood oxygen saturation values greater than 81% and less than 90% accounts for the total The amount of blood oxygen saturation value is greater than 91% and less than 95% accounts for 70% of the total amount, and the amount of blood oxygen saturation value greater than 96% and less than 100% accounts for 10% of the total amount.
分段统计区域中可以包含多个参数分区，某一个(些)参数分区相对于其他参数分区来说，具有特殊的意义。特殊意义可以具体是，能够为医护人员判断监测对象的健康状态提供指导意义。为了便于描述，可以将具有这种特殊意义的参数分区称为目标参数分区。目标参数分区可以是正常情况对应的参数分区，或者可以是异常情况对应的参数分区，或者还可以是通过医疗手段进行治疗后所想要达到的参数分区。目标参数分区具体为哪个或哪些参数分区，可以是***预先设置的，也可以由用户进行选择设置。The segmented statistical area may include multiple parameter partitions, and one or more parameter partitions have special significance compared to other parameter partitions. The special meaning may specifically be that it can provide guidance meaning for the medical staff to judge the health status of the monitored object. For the convenience of description, a parameter partition having such a special meaning may be referred to as a target parameter partition. The target parameter partition may be a parameter partition corresponding to a normal situation, or may be a parameter partition corresponding to an abnormal situation, or may be a parameter partition desired after treatment by medical means. The specific parameter partition or target parameter partitions can be preset by the system or selected by the user.
为了对目标参数分区进行区分，可以采用不同于其他参数分区的显示样式对所述目标参数分区和/或所述目标参数分区对应的分布统计结果进行显示。In order to distinguish the target parameter partition, a display style different from other parameter partitions may be used to display the target parameter partition and / or the distribution statistical result corresponding to the target parameter partition.
以血氧统计为例，将正常情况对应的统计区间区分显示，如图2F所示，正常情况对应的统计区间为[91％]-95％]，则将该统计区间填充背景色。当然，区分显示方式并不局限于颜色，还可以通过添加图标符号等形式进行区分。Taking blood oxygen statistics as an example, the statistical interval corresponding to the normal situation is displayed separately. As shown in FIG. 2F, the statistical interval corresponding to the normal situation is [91%]-95%], and the statistical interval is filled with the background color. Of course, the distinguishing display method is not limited to colors, and can also be distinguished by adding icon symbols and the like.
见图2G及2H，其示出了呼吸事件回顾界面的又一示例。需要说明的是，该两个图示表示的是同一个示例，只不过图2H中使用的英文概念在图2G中使用中文表示。以下主要对图2G的布局进行说明，图2H的相关说明同理可知。See Figures 2G and 2H, which illustrate yet another example of a respiratory event review interface. It should be noted that the two illustrations represent the same example, except that the English concept used in FIG. 2H is expressed in Chinese in FIG. 2G. The following mainly describes the layout of FIG. 2G, and the related description of FIG. 2H can be obtained by the same principle.
如图2G所示，该呼吸事件回顾界面包含关系图表区域261、单事件展示区域262、次数统计区域263的基础上，还包括功能按键区域264。需要说明的是，有关关系图表区域261、单事件展示区域262、次数统计区域263的说明可以参见上文，以下仅对功能按键区域264进行说明。As shown in FIG. 2G, the breathing event review interface includes a relationship chart area 261, a single event display area 262, and a number of times statistics area 263, and further includes a function key area 264. It should be noted that, for the description about the relationship chart area 261, the single event display area 262, and the number of times statistics area 263, please refer to the above, and only the function key area 264 is described below.
功能按键区域264中包含窗口(window)选择子区域，在该子区域内可以选择回顾时长，回顾时长也即本申请中提及的预设时间段。如图2G所示，可以将预设时间段选择为24小时，当然也可以选择其他数值，如12小时、8小时等。需要说明的是，设置的该时间段既可以作为步骤1.1中预设时间段的长度，也可以作为关系图表中时间坐标轴的长度，又可以作为统计呼吸事件发 生次数的时间段，还可以作为血氧统计中的预设时间段等等。The function key area 264 includes a window selection sub-area. In this sub-area, a review period can be selected, and the review period is also a preset time period mentioned in this application. As shown in FIG. 2G, the preset time period can be selected as 24 hours, and of course, other values such as 12 hours and 8 hours can also be selected. It should be noted that the set time period can be used not only as the length of the preset time period in step 1.1, but also as the length of the time axis in the relationship chart, and as a time period for counting the number of occurrences of respiratory events. Preset time period in blood oxygen statistics and so on.
功能按键区域264中还包含标记(mark)按钮，在选中某个呼吸事件的情况下，可以点击该按钮，从而弹出标记界面。标记界面中包含呼吸事件的关联信息，在标记界面中可以修改呼吸事件的关联信息，如修改呼吸事件关联的皮肤颜色等。The function button area 264 also includes a mark button. When a certain breathing event is selected, the button can be clicked to pop up a mark interface. The labeling interface contains the related information of the respiratory events, and the labeling interface can modify the related information of the respiratory events, such as modifying the skin color associated with the respiratory events.
如图3A-3D所示，为一种标记界面的示意图。呼吸事件的回顾显示方法还包括：响应用户输入的指令，提供一标记界面；保存用户通过所述标记界面输入的呼吸事件的关联信息。As shown in FIGS. 3A-3D, it is a schematic diagram of a marking interface. The method for retrospectively displaying respiratory events further includes: providing a marker interface in response to an instruction input by the user; and storing associated information of the respiratory events input by the user through the marker interface.
在一实施例中，标记界面包括呼吸事件展示区域301和显示呼吸事件关联信息的关联信息区域302，呼吸事件的回顾显示方法还包括：根据用户在呼吸事件展示区域内选择的呼吸事件，在标记界面的关联信息区域显示对应于所选择的呼吸事件的关联信息；并且保存用户通过标记界面的关联信息区域输入的关联信息。In an embodiment, the labeling interface includes a respiratory event display area 301 and a related information area 302 displaying respiratory event related information. The retrospective display method of the respiratory event further includes: according to the respiratory event selected by the user in the respiratory event display area, The association information area of the interface displays association information corresponding to the selected breathing event; and saves the association information input by the user through the association information area of the marker interface.
标记界面包括呼吸事件展示区域和显示呼吸事件关联信息的关联信息区域，其中所述呼吸事件展示区域包含至少一个呼吸事件的相关信息，相关信息包括呼吸事件的发生时间点及事件类型标记。见图3A及3B，其示出了本申请提供的标记界面的一个示例。如图3A所示，标记界面包括呼吸事件展示区域301，该区域内包含有历史24小时内所发生的呼吸事件的发生事件点以及事件类型标记。如果该区域内不能同时展示全部呼吸事件，可以通过触控滑动的方式，查看未显示的呼吸事件。另外，该区域内的呼吸事件可以参照发生事件先后顺序依次展示。The labeling interface includes a respiratory event display area and an associated information area displaying related information of the respiratory event, wherein the respiratory event display area includes information about at least one respiratory event, and the related information includes a time point of occurrence of the respiratory event and an event type mark. See Figures 3A and 3B, which show an example of a marker interface provided by the present application. As shown in FIG. 3A, the marker interface includes a respiratory event display area 301, which contains the occurrence event points and event type markers of the respiratory events that occurred in the past 24 hours. If all breathing events cannot be displayed in this area at the same time, you can view the breathing events that are not displayed by touching and swiping. In addition, the breathing events in this area can be shown in turn according to the sequence of occurrence of the events.
医护人员如果需要对某个呼吸事件输入关联信息，则可以点击呼吸事件展示区域中的该呼吸事件，如图3A及3B所示，假设选择的呼吸事件为第一个，即9点30分发生的ABD呼吸事件。If the medical staff needs to input relevant information for a breathing event, they can click on the breathing event in the breathing event display area, as shown in Figures 3A and 3B. Assume that the selected breathing event is the first, that is, 9:30. ABD breathing event.
点击呼吸事件展示区域的操作可以生成对目标呼吸事件的设置指令。基于设置指令，显示关联信息区域，其中关联信息区域中包含呼吸事件的关联信息的可选参数项，关联信息为用于辅助判断呼吸事件严重程度的信息。如图6A所示，标记界面包括关联信息区域302，该区域内包含的内容如下所述：Clicking on the breathing event display area can generate setting instructions for the target breathing event. Based on the setting instruction, an associated information area is displayed, where the associated information area contains optional parameter items of the associated information of the respiratory event, and the associated information is information used to assist in determining the severity of the respiratory event. As shown in FIG. 6A, the tagging interface includes an associated information area 302, and the content contained in this area is as follows:
皮肤颜色(skin color)的可选参数项分别包括：红润(pink)、灰白(dusky)、绀紫(cyanotic)、斑点(mottled)、黄疸(jaundice)；The optional parameters of skin color include: pink, dusky, cyanotic, mottled, and jaundice.
刺激程度(stimulation)的可选参数项分别包括：强(vigorous)、中 (moderate)、弱(mild)、无(none)；The optional parameters of stimulation include: strong (vigorous), medium (moderate), weak (mild), none (none);
自定义(custom)的可选参数项分别包括：机械通气(mechanical ventilation)、喂养(feed)。Custom optional parameters include: mechanical ventilation (ventilation), feeding (feed).
需要说明的是，图3B中的英文概念与图3A对应位置的中文概念具有同等含义。It should be noted that the English concept in FIG. 3B has the same meaning as the Chinese concept at the corresponding position in FIG. 3A.
之所以选择这些信息作为关联信息进行记录，是因为，这些关联信息可以在一定程度上能够反映该呼吸事件的严重程度。The reason for selecting this information for recording is that the related information can reflect the severity of the respiratory event to a certain extent.
关联信息的可选择项用于反映目标呼吸事件发生时，目标对象的情况。医护人员可以根据当时临床记录的信息，选择相应的可选择项。The selectable items of correlation information are used to reflect the situation of the target object when the target breathing event occurs. Medical personnel can choose corresponding options based on the information of clinical records at that time.
获得用户在可选择项中选择的项目后，建立与对应的呼吸事件的关联关系；并在呼吸事件的相关信息中，保存该关联关系。保存的内容作为呼吸事件的补充内容，有助于医护人员更完整地了解一条事件的全貌。After obtaining the item selected by the user among the selectable items, establish an association relationship with the corresponding respiratory event; and save the association relationship in the relevant information of the respiratory event. The saved content is used as a supplement to the respiratory event, which helps medical personnel to have a more complete picture of an event.
另外，关联信息区域还可以包含有另一种关联信息及可选择项。关联信息还包括表示呼吸事件有效或无效的属性。呼吸暂停事件监测方法还包括：将无效的呼吸事件在统计结果中排除，例如，将无效的呼吸事件在时间显示区域的时间轴上排除、在分段统计中排除、在次数统计中排除等等。如图3A及3B所示，即：是否进入ABD事件的统计(count into ABD total)：是或否。In addition, the related information area may also contain another related information and optional items. Associated information also includes attributes that indicate whether a respiratory event is valid or invalid. Apnea event monitoring methods also include: invalid breathing events are excluded from statistical results, for example, invalid breathing events are excluded from the time axis of the time display area, excluded from segmented statistics, excluded from frequency statistics, etc. . As shown in Figures 3A and 3B, that is: statistics of whether to enter ABD events (count into ABD total): Yes or No.
临床上医护人员比较关注呼吸事件的发生频率和次数，在一段时间内频发呼吸事件，则表示患者状况不好，需要医生及时干预。但是，临床上的某些操作或外接干扰也有可能导致患者短时间的异常，例如，给患儿喂奶，可能会导致吞咽时呼吸停止，或者给患儿擦身换尿布等也有可能因为患儿临时***问题导致呼吸暂停，如果护士及时处理就会解除这种风险。如果将这类问题纳入呼吸事件统计并不利于医生了解患者有价值的呼吸事件发生频率，所以提供了是否将该事件纳入ABD事件统计的选项。如果选择是(即有效)，则在会呼吸事件回顾界面或事件列表区域中统计显示；如果选择否(即无效)，则不会纳入呼吸事件回顾界面或事件列表区域中统计显示。Clinical staffs pay more attention to the frequency and frequency of respiratory events. Frequent respiratory events over a period of time indicate that the patient's condition is not good and doctors need to intervene in time. However, some clinical operations or external interference may also cause the patient to be abnormal for a short time. For example, feeding the child may cause breathing to stop when swallowing, or changing the child ’s diaper. Position problems lead to apnea, and this risk can be lifted if nurses address them in a timely manner. If this type of problem is included in the respiratory event statistics, it is not conducive for the doctor to understand the frequency of the patient's valuable respiratory events, so the option of whether to include this event in the ABD event statistics is provided. If you select Yes (that is, valid), the statistics are displayed in the respiratory event review interface or event list area; if you select No (that is, invalid), the statistics display in the respiratory event review interface or event list area is not included.
见图3C及图3D，其示出了标记界面的另一种形式，即呼吸事件展示区域中仅包括当前发生的呼吸事件的相关信息，仅对该呼吸事件进行关联信息的设置。需要说明的是，图3D中的英文概念与图3C对应位置的中文概念具有同等含义。该两个图示中的其他内容可以参见上述图3A中的说明，此处并不赘述。See FIG. 3C and FIG. 3D, which show another form of the labeling interface, that is, the respiratory event display area includes only relevant information of the currently occurring respiratory event, and only the related information of the respiratory event is set. It should be noted that the English concept in FIG. 3D has the same meaning as the Chinese concept at the corresponding position in FIG. 3C. For other contents in the two illustrations, reference may be made to the description in FIG. 3A described above, and details are not described herein.
需要说明的是，图3A-3D中还可以包含取消(cancel)及保存(save)按钮，以分别：取消标记界面及保存设置区域内的关联信息。It should be noted that FIGS. 3A-3D may further include cancel and save buttons to respectively: cancel the mark interface and save the associated information in the setting area.
功能按键区域264中还包含左移游标“<”及右移游标“>”，通过触控该两个游标可以在关系图表区域中切换选择呼吸事件。The function key area 264 further includes a left cursor “<” and a right cursor “>”, and by touching these two cursors, a breathing event can be switched and selected in the relationship chart area.
见图2I及2J，其示出了呼吸事件回顾界面的又一示例。需要说明的是，该两个图示表示的是同一个示例，只不过图2J中使用的英文概念在图2I中使用中文表示。以下主要对图2I的布局进行说明，图2J的相关说明同理可知。See Figures 2I and 2J, which illustrate yet another example of a respiratory event review interface.
