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

Continuous positive airway pressure (CPAP) therapy is a widely recognized and effective treatment for obstructive sleep apnea (OSA). This therapy involves using a CPAP machine that delivers a steady stream of air through a mask worn over the nose and/or mouth during sleep. The air pressure keeps the airways open, preventing the episodes of obstruction that characterize OSA.

The primary goal of CPAP therapy is to ensure unobstructed airflow during sleep, which significantly improves oxygen levels in the blood, enhances sleep quality, and alleviates daytime sleepiness. It is often recommended as the first-line treatment for moderate to severe cases of OSA, and it is supported by extensive clinical research demonstrating its effectiveness in reducing the severity of symptoms and improving overall health outcomes for patients.

The other options do not effectively address the primary problem of airway obstruction during sleep, making them less suitable as treatments for OSA.
