在连接有文本显示器的可编程控制器 12呼吸控制分***的控制 下， 交替发出高电平和低电平信号， 完成动物的吸气、 呼气动作。 当 可编程控制器 12呼吸控制分***发出高电平信号时候， 电指令使常 闭型电动吸气三通阀 9由平时的关闭状态转换为开放状态，由此混合 氧气进入动物体内， 与此同时常开型电动呼气三通阀 10由平时的常 开状态转换为关闭状态，混合氧气相应只能进入动物体内而不会排除 体外， 结果完成吸气动作； 当可编程控制器 12呼吸控制分***发出 低电平信号时候，此常闭型电动吸气三通阀 9由吸气时候的开放状态 回复到原先的闭合状态， 混合氧气停止进入动物体内， 与此同时常开 型电动呼气三通阀 10由吸气时的闭合状态回复到原先的开放状态， 由于动物胸廓的自然回缩，气体相应排除体外，结果是完成呼气动作。

(1) 胸外按压 /机械通气=^ 1 (N=l， 2, 3……任意整数）， 本实例为 2: 1； 胸外按压 /机械通气比例和频率可根据研究需要进行 任意调节。
