powered-by="gulangu"><p><span><strong>一、原理</strong></span></p><p><span><strong>空气：呼吸机经进气口的空气过滤片吸入周围的空气。（保证进来的气体是干净的）</strong></span></p><p><span><strong>并由送气机增压，经过限压阀(PVA)对系统流量及压力调节后。（为呼吸机提供合适的动力源。限压阀PVA受控于气流电子压力系统（PAS）。）</strong></span></p><p><span><strong>来到气流模块（AFM）相当于流量传感器，监测呼吸机总体的气体流量，并将数据传送到主控制子系统（MCS）。</strong></span><strong>最后将空气送到到外部呼吸管路中。（取决于屏幕控制子系统（D/CS）输入的参数信号，传送到主控制子系统（MCS）和气流电子压力系统（PAS），来决定气体的流量和压力。同时将数据显示在屏幕上。）</strong></p><p><strong>氧气：终端上的氧气经呼吸机的氧气模块控制后。（氧气模块受控于MCS，用来调节氧浓度。）</strong></p></section><section

powered-by="gulangu"><p><strong>经过气流模块（AFM），和空气一起汇入，送到外部呼吸管路中。</strong></p><p><strong>外部呼吸管路：是一个闭合回路，通过压力管来监测呼吸回路的气体压力。</strong></p><p><strong>压力管将压力信号传送到主控制子系统（MCS）。</strong></p></section><section

powered-by="gulangu"><p><strong>二、分析</strong></p></section><section powered-by="gulangu"><p><strong>自检能通过说明呼吸机内部关键部位的元器件没有问题。</strong></p><p><strong>能正常通气说明整个呼吸系统，控制模块功能正常。</strong></p><p><strong>屏幕上没有任何报错，说明呼吸机关键参数正常。</strong></p><p><strong>以上三点足以证明呼吸机没有任何问题，可能有隐藏报错或者遗留报错没有消除掉。</strong></p><p><strong>通过进入报错信息里面的报错代码201，且无法清除，可以断定就是它引发的长鸣。</strong></p></section><section
