continuous positive airway pressure

a method of medical gas administration in which gas is delivered to the patient at positive pressure in order to hold open alveoli that would normally close at the end of expiration and thereby increase oxygenation, preventing atelectasis, and reduce the work of breathing; abbreviated CPAP. It is used with patients who are breathing spontaneously. When the same principle is used in mechanical ventilation, it is called positive end-expiratory pressure.
