Pressure-controlled assist/control ventilation (PC-ACV) 7.3.2.5
Like PC-SIMV, the assist/control mode is a synchronized ventilation
mode. In PC-ACV mode, however, the ventilator supports all of the
patient’s own breathing efforts that exceed the preset trigger threshold
with a mechanical breath. This triggers the patient's mandatory
inspiration, but its characteristic is controlled by the device. The patient
cannot trigger a new mandatory breath until this time has elapsed.
