There is presently considerable ambiguity and confusion relating to ventilator terminology. This can be eliminated using a simple approach, visualising mechanical ventilation as an inspiratory pump, and defining trigger, limit, and cycling in this context. The trigger is the signal that starts a breath by opening the inspiratory valve, the limit is the factor which controls the way gas flows into the lung, and the cycle is the signal that stops the breath by closing the inspiratory valve and opening the expiratory valve. By identifying these three basic parameters, one can precisely dissect and interpret any of the vast ventilatory terminology.
目前，呼吸机术语存在相当大的模糊性和混淆。使用一种简单的方法可以消除这种情况，即将机械通气视为一个吸气泵，并在此背景下定义触发、限制和切换。触发是通过打开吸气阀启动一次呼吸的信号，限制是控制气体流入肺部方式的因素，而切换是通过关闭吸气阀并打开呼气阀来停止呼吸的信号。通过识别这三个基本参数，人们可以精确剖析和解释众多通气术语中的任何一个。
