Continuous Positive Airway Pressure (CPAP)

CPAP applies a constant level of pressure at the airway opening during spontaneous breathing, acting as a splint that prevents throat collapse and maintains regular breathing.

CPAP is most constantly used in the treatment of obstructive sleep apnea (OSA), a sleep-related breathing disorder in which airflow decreases or stops when soft tissue in the back of the throat collapses and blocks the airway.
