Continuous Positive Airway Pressure

A treatment method using mild air pressure to keep the airways open, usually for people with breathing problems during sleep.

Expiratory Pressure

The pressure in the airways of the lungs during expiration, critical in respiratory care and ventilation settings.

Bi-Level Positive Airway Pressure
