The primary goal of CPAP (Continuous Positive Airway Pressure) therapy is to prevent airway collapse during sleep. CPAP accomplishes this by providing a constant flow of air through a mask that keeps the upper airway passages open, thereby preventing obstructive events that occur in conditions such as obstructive sleep apnea (OSA). By maintaining a patently open airway, CPAP significantly reduces the occurrence of apneic episodes that can disrupt sleep and lead to further complications.

While stimulating REM sleep, increasing sleep duration, and reducing nighttime awakenings are beneficial outcomes that may result from effective CPAP therapy, they are secondary effects. The core function of CPAP is to maintain an unobstructed airway, which is vital for proper ventilation and continuous, uninterrupted sleep. Addressing this primary need can lead to improved overall sleep quality and greater health benefits for individuals suffering from sleep-disordered breathing.
