What is the primary purpose of Continuous Positive Airway Pressure (CPAP)?

The primary purpose of Continuous Positive Airway Pressure (CPAP) is to maintain open airways during sleep. CPAP is a common treatment for obstructive sleep apnea, a condition where the throat muscles intermittently relax and block the airway during sleep. By delivering a continuous stream of air through a mask, CPAP helps to keep the upper airway open, preventing the pauses in breathing that characterize sleep apnea episodes. This uninterrupted airflow allows the individual to breathe normally throughout the night, leading to improved sleep quality and overall health.

While increasing oxygen levels, monitoring sleep patterns, and enhancing REM sleep may be related to the broader context of sleep medicine, they are not the primary functions of CPAP. The device specifically addresses airway obstruction rather than directly affecting oxygen levels or sleep cycles. Thus, maintaining an open airway is the fundamental role of CPAP therapy.
