WebBasics of ventilator waveforms. Ventilator waveforms show three key parameters: pressure, flow, and volume. The curves in a ventilator waveform can represent … WebTrigger function. 1. Spontaneous breathing is detected using a flow measurement. Trigger sensitivity may be set from 1 to 10 to avoid autotriggering. At the highest sensitivity setting, trigger volume is 0 and inspiratory flow will trigger a breath when it reaches a minimum value of 0.2 L/min. 2. Trigger response time is 40 to 60 msec. IV.
