CPAP
Pronunciation: SEE-pap
Also written as: CPAP — continuous positive airway pressure
Continuous positive airway pressure therapy device that delivers pressurized air to keep airways open during sleep.
Full Definition
Continuous positive airway pressure (CPAP) is the gold standard treatment for obstructive sleep apnea, delivering a constant stream of pressurized air through a mask to maintain airway patency during sleep. The device consists of a motor that generates airflow, a humidifier, tubing, and a nasal or full-face mask. CPAP pressure is typically titrated during a sleep study or through auto-titrating devices to determine the optimal therapeutic pressure. Effective CPAP therapy can dramatically reduce apnea events, improve sleep quality, and reduce cardiovascular risks associated with untreated sleep apnea.
Usage
Usage note: Always use all caps for the acronym. When referring to pressure settings, use 'cm H₂O' notation.
In Context
- "The patient was prescribed CPAP therapy at 8 cm H₂O pressure for treatment of moderate sleep apnea." — Sleep clinic treatment plan
- "CPAP compliance data showed the patient used the device for an average of 6.5 hours per night." — Follow-up appointment note
