Pressure support (PS) is a mode of ventilation in which the patient's spontaneous respiratory activity is augmented by the delivery of a preset amount of inspiratory positive pressure. Positive end-expiratory pressure provides positive pressure at end expiration during mechanical breaths, and continuous positive airway pressure provides positive pressure during spontaneous breaths. The T-piece adapter is used to provide oxygen with spontaneous, unassisted breaths.
