Question

Quizplus · Accepted Answer

Pressure triggering occurs when a patient's inspiratory effort causes a drop in pressure within the breathing circuit. When this pressure drop reaches the pressure sensing mechanism, the ventilator triggers on and begins gas delivery. On most ventilators, you can adjust the pressure drop needed to trigger a breath. The trigger level is often called the sensitivity.
