Which of the following is a typical treatment for obstructive sleep apnea?

Continuous positive airway pressure (CPAP) therapy is the standard treatment for obstructive sleep apnea (OSA) because it directly addresses the condition's underlying mechanism. OSA is characterized by repetitive episodes of airway obstruction during sleep, leading to disrupted breathing, frequent awakenings, and potential cardiovascular issues. CPAP works by delivering a continuous stream of air through a mask, which keeps the airway open and prevents the collapse that causes apneas. This therapy has been shown to improve sleep quality, reduce daytime sleepiness, and lower the risk of associated health complications such as hypertension and heart disease.

Other options, while they might seem beneficial in promoting sleep or wakefulness, do not address the specific airway obstruction that defines OSA. Increasing caffeine intake, for instance, may temporarily reduce sleepiness but is not a treatment for obstructive sleep apnea and can actually worsen sleep quality. Longer sleep duration might seem helpful, but without maintaining an open airway during sleep, it won't effectively mitigate the symptoms of OSA. Daily napping may provide relief from daytime drowsiness but does not resolve the fundamental problem of airway obstruction during nighttime sleep. Therefore, the use of CPAP therapy remains the most effective and evidence-based approach for managing obstructive sleep apnea.
