摘　　要：目的:对临床上几款呼吸机加呼气末正压(PEEP)时的误触发分析其原因和相应的对策。方法:主要对在不同的呼吸机上20例故障根据其使用年限进行故障归类。结果:发生呼气阀和周边管路漏气故障65％,传感器(压力和流量)的损坏25％,电磁阀的老化10％,生物医学工程的故障排除是处理的实用方法。结论:呼气调和周边管路漏气,传感器损坏及电磁阀老化是3种主要故障。Objective: To analyze the causes of error trigger about several types of respiratory machine when their mechanical ventilations were used with PEEP and to bring forward the countermeasure.Methods: To classify 20 faults of error trigger in different machines according to the usage years.Results: The principal faults of error trigger are: leakage of expiratory valve and circuit(65%), damage of sensor(25%) and aging of electromagnetic valve(10%) .Conclusion:To bring forward the practical measures to deal with the three principal faults.
