Pressure-sensitive ventilator disconnection alarms may fail to function correctly when used with discharging compliance ventilators such as the Manley Blease. The increase in gas flow on disconnection generates raised pressure owing to the resistance provided by components of the breathing system. Thirty-four anaesthetists, who were unaware of the nature of the survey, were observed to see if previous recommendations for the correct adjustment of the ventilator alarm were being followed. It was found that 77% of alarms were incorrectly adjusted and would not have alarmed in the event of a true disconnection occurring.
当与诸如曼利·布利斯(Manley Blease)等具有排出顺应性的呼吸机一起使用时,压力感应式呼吸机断开连接警报可能无法正常工作。断开连接时气流的增加会由于呼吸系统组件提供的阻力而产生压力升高。观察了34名不知道调查性质的麻醉师,看他们是否遵循了之前关于正确调整呼吸机警报的建议。结果发现,77%的警报调整错误,如果真的发生断开连接,这些警报不会发出警报。
