The ventilator mode that is either patient triggered or time triggered and allows the patient to breathe spontaneously between mandatory ventilator breaths is known as:
a. Pressure-support ventilation c. Intermittent man-datory ventilation
b. Pressure-controlled ventilation d. Continuous man-datory ventilation
ANS: C
Intermittent mandatory ventilation is designed to deliver volume-targeted or pressure-targeted breaths at a set minimum frequency (i.e., it is time triggered). Between mandatory breaths, the patient can breathe spontaneously from the ventilator circuit without getting the set volume or pressure from the ventilator itself.
