The primary goal of continuous positive airway pressure (CPAP) therapy is to keep the airway open during sleep. This therapeutic approach is essential for individuals suffering from obstructive sleep apnea (OSA), a condition where the airway becomes blocked or collapses multiple times during sleep. By delivering a steady stream of air through a mask, CPAP prevents the airway from narrowing or closing, allowing for uninterrupted breathing and thus reducing the number of apnea events. This, in turn, supports better oxygenation and can lead to improvements in overall health.

While inducing sleep faster, reducing daytime drowsiness, and enhancing sleep quality may be associated benefits of effectively using CPAP, they are not the primary objectives of the therapy itself. The main focus remains on maintaining an open airway to address the critical issue of apnea, ensuring the patient can breathe freely throughout the night.
