What is the potential benefit of using continuous positive airway pressure (CPAP) therapy for patients diagnosed with sleep apnea?

Continuous positive airway pressure (CPAP) therapy serves a critical role in managing sleep apnea, primarily by preventing airway collapse during sleep. In obstructive sleep apnea, the airway can become blocked due to the relaxation of throat muscles and tissues, leading to breathing interruptions that can affect sleep quality and overall health. CPAP works by delivering a steady stream of air through a mask that keeps the airways open, thereby preventing these collapses and ensuring that the patient can breathe properly throughout the night.

This treatment not only helps in reducing the frequency of apneas but also improves oxygen saturation levels in the blood and can alleviate daytime symptoms such as fatigue and excessive sleepiness. By maintaining an open airway, CPAP contributes to more restorative sleep cycles that can enhance overall health and well-being.

While the other options might suggest benefits associated with sleep improvements or weight management, they do not specifically address the core functionality of CPAP therapy in the context of preventing airway collapse, which is vital for treating sleep apnea effectively.
