We introduce a method for inspecting the function of the respiratory circuit of an anesthesia machine using "Valve Checker" devised by a manufacturer. With this method, the function of an inspiratory valve can be confirmed by the pressure not being removed when pressure is applied by connecting the "Valve Checker" directly with the inspiratory opening. Additionally, the function of an expiratory valve can be confirmed by the pressure being removed and also by the deflated bag being inflated when pressure is applied by connecting the "Valve Checker" directly with an expiratory opening. This is a method whereby a delicate cushioning of pressure by a hose is excluded and the function of the inspiratory valve and expiratory valve can be inspected independently and easily.
我们介绍一种使用制造商设计的“阀门检查器”来检查麻醉机呼吸回路功能的方法。通过这种方法，将“阀门检查器”直接连接到吸气口施加压力时，如果压力没有被释放，就可以确认吸气阀的功能。此外，将“阀门检查器”直接连接到呼气口施加压力时，如果压力被释放且瘪掉的袋子膨胀，就可以确认呼气阀的功能。这是一种排除软管对压力的微妙缓冲作用的方法，能够独立且轻松地检查吸气阀和呼气阀的功能。
