CPAP
Pronunciation: SEE-pap
Also written as: CPAP — Continuous Positive Airway Pressure
Continuous Positive Airway Pressure; non-invasive ventilatory support that maintains constant positive pressure throughout the breathing cycle.
Full Definition
Continuous Positive Airway Pressure (CPAP) is a form of non-invasive positive pressure ventilation that delivers a constant level of positive pressure to the airway throughout both inspiration and expiration. CPAP helps maintain alveolar recruitment, reduces work of breathing, and improves oxygenation without requiring endotracheal intubation. Respiratory therapists commonly use CPAP for treating sleep apnea, acute pulmonary edema, and post-extubation respiratory support.
Usage
Usage note: Always capitalize when used as acronym; can be used as both noun and adjective.
