Pressure support is an assist mode of ventilation that augments a patient's spontaneous effort with positive pressure.On initiation of a breath,a constant pressure (preset)is delivered until the flow rate reaches approximately 25% of the peak inspiratory flow.This mode assures that the patient's spontaneous breaths are large enough to maintain adequate blood gases
