When you adjust the pressure drop necessary to trigger a breath on a ventilator, what are you ad-justing on the machine?

a. Sensitivity
b. Pressure limit
c. Mode setting
d. Positive end expiratory pressure (PEEP) level


ANS: A
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.
