Therefore, whether the target breathing machine has a breathing event in a preset time period can be judged through the generated operation parameter information and the historical operation parameter information.

The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Fig. 1 illustrates a flow 100 of some embodiments of a respiratory event alerting method according to the present disclosure. The respiratory event alarming method comprises the following steps:

step 101, collecting a gas circulation information set of a target breathing machine in a preset time period.

In some embodiments, the subject (e.g., computing device) performing the respiratory event alerting method may obtain gas flow from the gas flow sensor and gas pressure from the pressure sensor over a wired or wireless connection for a preset period of time. The gas flow and gas pressure obtained each time may then be combined into gas flow information. Finally, the combined individual gas flow information may be determined as a gas flow information set. Each gas flow information may correspond to a sub-period of time. For example, the preset time period may be a 15 second time period. One sub-period may be a period of 1 second. Here, the preset time period may be a time period from the current start to a future time. The target breathing machine may be the executing body, that is, a breathing machine in a state of being worn by a user, which is currently required to detect a respiratory event. The gas flow sensor and the pressure sensor may be provided in the target ventilator.

It should be noted that the wireless connection may include, but is not limited to, 3G/4G connections, wiFi connections, bluetooth connections, wiMAX connections, zigbee connections, UWB (ultra wideband) connections, and other now known or later developed wireless connection means.

And 102, generating operation parameter information of the target breathing machine in a preset time period according to each gas flow and each gas pressure included in the gas circulation information set.

In some embodiments, the executing body may generate the operation parameter information of the target ventilator in the preset time period according to each gas flow rate and each gas pressure included in the gas flow information set.

In some optional implementations of some embodiments, the executing entity may generate the operating parameter information of the target ventilator for the preset time period by:

in the first step, the variance of each gas flow is determined as the gas flow variance.

And step two, performing filtering treatment on each gas pressure to obtain a filtered gas pressure set. In practice, the execution body may perform filtering processing on each gas pressure by using a filtering algorithm, so as to obtain a filtered gas pressure set. For example, the filtering algorithm may be a high pass filtering algorithm.

And thirdly, combining the gas flow variance and the filtered gas pressure set into operation parameter information. Here, the combination may be splicing.

The execution body may determine the standard deviation of each gas flow rate as a gas flow rate standard deviation, and quantify the gas flow rate from a dimension of the standard deviation.

Step 103, acquiring a historical gas flow information set of the target breathing machine in a preset historical time period.

In some embodiments, the executing entity may obtain a historical gas flow information set of the target ventilator over a preset historical period of time. Wherein, the historical gas flow information in the historical gas flow information set may include a historical gas flow. The preset history period may be a period in which a time interval is greater than a history time of the preset period. For example, the above-described preset history period may be a period of one minute in the past. In practice, the executing body may acquire the historical gas flow information set in the preset historical time period from the local memory. Each of the historical gas flow information in the set of historical gas flow information may correspond to a sub-historical time period. For example, the sub-history period may be a one second history period.

And 104, generating historical operation parameter information of the target breathing machine in a preset historical time period according to each historical gas circulation quantity included in the historical gas circulation information set.

In some embodiments, the executing entity may generate the historical operating parameter information of the target ventilator in the preset historical time period according to the respective historical gas flow amounts included in the historical gas flow information set.

In some optional implementations of some embodiments, the executing entity may generate the historical operating parameter information of the target ventilator for the preset historical period of time by:

in the first step, the variance of each of the above-mentioned historic gas flows is determined as the historic gas flow variance.

And secondly, determining the historical gas flow variance as historical operation parameter information.

The execution body may determine the standard deviation of each of the historical gas flows as a historical gas flow standard deviation, and quantify the historical gas flow from a dimension of the standard deviation.

Step 105, determining whether the target ventilator has a respiratory event according to the operation parameter information and the historical operation parameter information.

In some embodiments, the executing entity may determine whether a respiratory event occurs with the target ventilator based on the operating parameter information and the historical operating parameter information.

In some optional implementations of some embodiments, the executing entity may determine whether a respiratory event occurs with the target ventilator by:

and a first step of determining the product of the historical gas flow variance included in the historical operation parameter information and a first preset coefficient as a reference gas flow variance. The first preset coefficient may be a value less than 1. For example, the first preset coefficient may be 0.5.

And a second step of determining whether the gas flow variance included in the operation parameter information is smaller than the reference gas flow variance.

And thirdly, inputting the filtered gas pressure set into a pre-trained target respiratory event recognition model to obtain a target respiratory event recognition result. The target respiratory event recognition model may be a model for recognizing whether a respiratory event occurs from a dimension of gas pressure. Here, the target respiratory event recognition model may be a machine learning model or a neural network model.

Alternatively, the target respiratory event recognition model may be a snoring event recognition model. The target respiratory event recognition result may be indicative of whether a snoring event has occurred with the target ventilator. For example, the target respiratory event recognition model may be a decision tree model with a filtered gas pressure set as input data and a target respiratory event recognition result characterizing whether a snoring event occurs as output data. The target respiratory event recognition model may include a first input layer, a first recognition model, a second input layer, a second recognition model, a third recognition model, a fourth recognition model, and a decision layer. Wherein the first input layer is connected to the first recognition model. The second input layer is connected with the first recognition model. The second input layer is connected to the second recognition model, the third recognition model, and the fourth recognition model. The decision layer is connected to the second recognition model, the third recognition model, and the fourth recognition model.

The first input layer may be used for extracting features of input data. The first 5-recognition model described above may be used to determine whether an abnormal respiratory event exists based on features extracted by the first input layer. The second input layer may be configured to extract features corresponding to abnormal respiratory events according to the recognition result of the first recognition model. The second recognition model, the third recognition model and the fourth recognition model can be different types of classification models and can be used for the second input

Features extracted by the layering that correspond to abnormal respiratory events identify the type of abnormal respiratory event. The 0 decision layer may be used to determine the first and second recognition models based on the first and second recognition models

And fourthly, identifying the classification result of the model, and determining whether the abnormal respiratory event is a snoring event or not so as to output a target respiratory event identification result. For example, the decision layer may determine, as the target respiratory event recognition result, a classification result satisfying a preset number of conditions among the respective classification results. Preset number of conditions

It may be "the number of identical classification results is 2". As an example, the classification results of the second and the third recognition models may be snoring events, and the classification result of the fourth recognition model may be hypopnea events. The decision layer may determine the snore event as the target respiratory event recognition result.

And step four, determining that the target breathing machine has a breathing event in response to determining that the operating parameter information comprises a gas flow variance smaller than the reference gas flow variance or that the target breathing event identification result represents the breathing event of the target 0 breathing machine. Thereby, it is possible to

Determining whether a respiratory event has occurred in a preset time period for the target ventilator from a variance of the gas flow or a dimension of the gas pressure.

And step 106, generating respiratory event alarm information in response to determining that the target breathing machine generates respiratory events.

In some embodiments, the executing entity may generate respiratory event alert information in response to determining that the target ventilator has a respiratory event. The respiratory event alarm information may be information indicating that the target ventilator has respiratory events and respiratory events. For example, the respiratory event alarm information may be "ventilator 001, and a respiratory event occurs. The ventilator 001 may be an identification of the target ventilator described above.

0 in some alternative implementations of some embodiments, the executing entity may generate the respiratory event alert information by:

and a first step of determining the product of the historical gas flow variance included in the historical operation parameter information and a second preset coefficient as a low ventilation event threshold. The second preset coefficient may be a preset value less than 1. Here, the second preset coefficient may be the same as the first preset coefficient.

And secondly, determining the product of the historical gas flow variance included in the historical operation parameter information and a third preset coefficient as an apnea event threshold. The third preset coefficient may be smaller than the second preset coefficient. For example, the third preset coefficient may be 0.2.

And a third step of determining the respiratory event type as an apneic event in response to determining that the operating parameter information includes a gas flow variance less than the apneic event threshold. Thus, it may be determined that an apneic event has occurred in the target ventilator within a preset time period when the gas flow variance is less than the apneic event threshold.

Fourth, determining the respiratory event type as a hypopnea event in response to determining that the operating parameter information includes a gas flow variance that is greater than the apneic event threshold and less than the hypopnea event threshold. Thus, it may be determined that the target ventilator has a hypopnea event within a preset period of time when the gas flow variance is greater than the apnea event threshold and less than the hypopnea event threshold.

And fifthly, determining the respiratory event type as a snoring event in response to determining that the target respiratory event identification result represents the occurrence of the snoring event by the target respiratory machine. Thus, it can be determined whether a snoring event has occurred through the target respiratory event recognition result.

And sixthly, generating respiratory event alarm information according to the determined respiratory event type.

In some optional implementations of some embodiments, the executing entity may generate the respiratory event alert information according to the determined respiratory event type by:

First, determining a target respiratory event number corresponding to the target ventilator. The number of the target respiratory events is the number of the respiratory events of the target breathing machine in the current starting state. In practice, the executing body may read the target respiratory event number corresponding to the target ventilator from the memory.

And secondly, updating the target respiratory event times to be the sum of the target respiratory event times and a preset value. Wherein, the preset value may be 1.

And thirdly, determining the respiratory event grade matched with the updated target respiratory event times according to a preset respiratory event time range set. Wherein, each respiratory event frequency range in the respiratory event frequency range set corresponds to a respiratory event grade. Here, the matching relationship between the target respiratory event number and the respiratory event class may be: the target respiratory event number is within a respiratory event number range corresponding to the respiratory event level. The respiratory event level may be a level of the number of respiratory events that occur after the target ventilator is turned on this time. The greater the number of respiratory events that occur, the higher the respiratory event level. For example, the respiratory event level corresponding to two respiratory events may be two-level.

And step four, determining a respiratory event alarming mode information set according to the determined respiratory event grade. The respiratory event alarm mode information in the respiratory event alarm mode information set comprises alarm terminal type and alarm prompt mode information. In practice, the executing body may select at least one preset respiratory event alarm mode information corresponding to the respiratory event level from a preset respiratory event alarm mode information set. The selected preset respiratory event alert mode information may then be determined as a respiratory event alert mode information set. For example, the preset respiratory event alert mode information corresponding to the secondary respiratory event level may include "alert terminal type: mobile phone end, alarm prompting mode information: text message prompt "," alarm terminal type: speaker, alarm prompt mode information: and (5) an audible alarm prompt. The mobile phone end can represent the mobile phone end corresponding to the target breathing machine to give an alarm. The mobile phone end corresponding to the target breathing machine can be the mobile phone end responsible for checking the target breathing machine. "text message prompting" may characterize a message in text form for prompting.

And fifthly, generating respiratory event alarm information according to the determined respiratory event type, the respiratory event alarm mode information set, the updated target respiratory event times and the determined respiratory event level.

In some optional implementations of some embodiments, the executing entity may generate the respiratory event alert information by:

first, determining the starting time of the target breathing machine in the current starting state.

And secondly, determining the ratio of the updated target respiratory event times to the starting-up duration as a respiratory event index.

And thirdly, determining whether the respiratory event index is larger than a preset respiratory event index. Here, the specific setting of the preset respiratory event index is not limited.

And step four, generating respiratory event index alarm information in response to determining that the respiratory event index is greater than the preset respiratory event index. In practice, the execution subject may combine the respiratory event index and a preset respiratory event index alarm prompt template into respiratory event index alarm information. For example, the preset respiratory event index alarm alert template may be "current respiratory event index ___, out of standard". Wherein the underlined section is to be filled with a respiratory event index. For example, when the respiratory event index is 6 and the preset respiratory event index is 5, the generated respiratory event index alarm information may be "the current respiratory event index is 6 and exceeds the standard".

And fifthly, combining the determined respiratory event type, the respiratory event alarm mode information set, the updated target respiratory event times, the determined respiratory event level and the respiratory event index alarm information into respiratory event alarm information. In practice, the executing body may use a stitching manner to combine the determined respiratory event type, the respiratory event alarm manner information, the updated target respiratory event number, the determined respiratory event level and the respiratory event index alarm information into respiratory event alarm information.

And step 107, controlling the associated alarm equipment to execute the respiratory event alarm operation according to the respiratory event alarm information.

In some embodiments, the executing body may control the associated alarm device to execute the respiratory event alarm operation according to the respiratory event alarm information. The alarm device may be a sound playing device associated with the executing body. For example, a speaker on the target ventilator described above. In practice, the alarm device may be controlled to play the respiratory event alarm information to perform a respiratory event alarm operation.

Optionally, for each respiratory event alert mode information in the respiratory event alert mode information set, the executing body may execute the steps of:

The first step, determining at least one alarm equipment identifier corresponding to the target breathing machine according to the type of the alarm terminal included in the breathing event alarm mode information. In practice, the executing body may select, from the alarm device identifiers corresponding to the target breathing machine, an alarm device identifier whose corresponding terminal type includes the alarm terminal type. The alarm devices corresponding to the target breathing machine may include, but are not limited to: cell-phone, landline, display device, audio amplifier. The alarm device identifier may uniquely identify the alarm device corresponding to the target ventilator. The terminal type may characterize the respective function that the alarm device has. For example, the terminal type corresponding to the mobile phone may be "sound playing device, display device".

And a second step of generating respiratory event alarm operation information corresponding to the alarm prompting mode information included in the respiratory event alarm mode information according to the respiratory event type, the target respiratory event times, the respiratory event level and the respiratory event index alarm information included in the respiratory event alarm information. Specifically, the executing body may input the respiratory event type, the target respiratory event number, the respiratory event level and the respiratory event index alarm information to a preset alarm prompt information template in response to determining that the alarm prompt mode information is an audible alarm prompt, so as to obtain alarm prompt information. The alarm terminal type corresponding to the alarm prompting mode information is sound playing equipment. The alarm prompt message template may be a text template for prompting an alarm. For example, the alert message template may be "respiratory event of _____ type has occurred currently, respiratory event has occurred ____ times, and current respiratory event level is ____, ____". Wherein the first underline is used to fill the respiratory event type. The second underline is used to fill the target respiratory event count. The third underline is used to fill the respiratory event class. The fourth underline is used to populate the respiratory event index alarm information. The sound playing device may be a device that can play sound. The sound playing device may include, but is not limited to: cell phone, speaker, audio amplifier. And then, according to the alarm prompt information, generating audio corresponding to the alarm prompt information as respiratory event alarm operation information. The audio corresponding to the alarm prompt message may be audio converted from the text of the alarm prompt message. And secondly, in response to determining that the alarm prompting mode information is a visual chart alarm prompting, inputting the respiratory event type, the target respiratory event times, the respiratory event grade and the respiratory event index alarm information into a preset visual prompting chart template to obtain an alarm prompting chart as respiratory event alarm operation information. The alarm terminal type corresponding to the alarm prompting mode information is display equipment. The display device may include, but is not limited to: cell phones, tablets, displays. The visual prompting chart template can be a chart template which is preset with visual chart patterns and can be automatically visualized into a chart according to input data. The obtained alarm prompt chart shows the breathing event type, the target breathing event frequency, the breathing event grade and the breathing event index alarm information.

And thirdly, for each determined alarm device identifier, controlling the alarm device corresponding to the alarm device identifier to execute the respiratory event alarm operation corresponding to the respiratory event alarm operation information. Specifically, in response to determining that the respiratory event alert operation information is audio, the alert device may be controlled to play the respiratory event alert operation information. In response to determining that the respiratory event alarm operation information is an alarm prompt chart, the alarm device may be controlled to display the respiratory event alarm operation information.

The related content of the respiratory event alarming operation information corresponding to the alarming prompt mode information is used as an invention point of the embodiment of the disclosure, so that the technical problem mentioned in the background art is solved, when the respiratory event is detected, only the currently detected respiratory event is alarmed, the operation condition of the ventilator after the current startup cannot be quickly known, and the alarming mode by the fixed ventilator is single. The factors that lead to the failure to quickly learn the operation condition of the ventilator after the current startup and the mode of alarming are single are often as follows: when a respiratory event is detected, only alarming the currently detected respiratory event; alarming is carried out through a fixed breathing machine. If the above factors are solved, the effects of quickly knowing the running condition of the breathing machine after the starting up and increasing the alarm mode can be achieved. To achieve this effect, the present disclosure introduces a respiratory event class from which respiratory event alert mode information is determined. Different respiratory event classes correspond to different respiratory event alarm mode information, namely different alarm terminal types and alarm prompt modes. Therefore, according to the generated respiratory event alarming operation information, alarming prompt can be carried out in a sound broadcasting or chart display mode. Thereby, the alarm mode is increased. In addition, the respiratory event alarming operation information comprises respiratory event type, target respiratory event times, respiratory event grade and respiratory event index alarming information, and the operation condition of the target breathing machine after the current startup can be rapidly obtained through the respiratory event alarming operation information. Therefore, a breathing event alarming mode is added, and the running condition of the breathing machine after the starting up can be rapidly obtained.

The above embodiments of the present disclosure have the following advantageous effects: by the respiratory event alarming method of some embodiments of the present disclosure, the number of false or delayed respiratory event alarms is reduced. Specifically, the reason for the greater number of false or delayed respiratory events is: the respiratory event is directly detected from the dimension of the exhalation quantity, so that the accuracy of the boundary alarm threshold value has larger influence on the detection result, and the number of false or delayed respiratory event is more. Based on this, the respiratory event alerting method of some embodiments of the present disclosure first collects a gas flow information set of a target ventilator within a preset time period. Wherein, the gas circulation information in the gas circulation information set comprises gas flow and gas pressure. Thus, the gas flow information set may characterize the respective gas flow and the respective gas pressure of the target ventilator over a period of time. And then, generating the operation parameter information of the target breathing machine in the preset time period according to each gas flow and each gas pressure included in the gas circulation information set. Thus, the operating parameter information may be used to determine whether a respiratory event has occurred in the target ventilator within a preset time period. And then, acquiring a historical gas flow information set of the target breathing machine in a preset historical time period. Wherein, the historical gas flow information in the historical gas flow information set comprises historical gas flow. Thus, the historical gas flow information set may characterize individual historical gas flows of the target ventilator over a period of time. And secondly, generating historical operation parameter information of the target breathing machine in the preset historical time period according to each historical gas circulation quantity included in the historical gas circulation information set. Thus, the historical operating parameter information may be used to compare and determine whether a respiratory event has occurred in the target ventilator within a preset time period. And then, determining whether the target breathing machine has a breathing event according to the operation parameter information and the historical operation parameter information. Therefore, whether the target breathing machine has a breathing event in a preset time period can be judged through the generated operation parameter information and the historical operation parameter information. Then, in response to determining that the target ventilator has a respiratory event, respiratory event alert information is generated. Thus, after determining that the target ventilator has a respiratory event within a preset time period, respiratory event warning information for warning can be generated. And finally, controlling the associated alarm equipment to execute respiratory event alarm operation according to the respiratory event alarm information. Therefore, the medical staff can be reminded to arrive at the respirator as soon as possible through the breathing event alarming operation of the alarming device. And when judging whether the breathing event occurs in the breathing machine, the judgment of the boundary alarm threshold is not directly carried out through the gas flow, but the comprehensive judgment is carried out on the operation parameter information of the target breathing machine in the preset time period and the historical operation parameters in the historical time period, and the setting of the specific threshold is not involved. Therefore, the influence of the accuracy of the boundary alarm threshold on the detection result is avoided, and the number of false alarms or delayed alarms of respiratory events is reduced.
