What is the primary purpose of using a CPAP machine for the treatment of obstructive sleep apnea (OSA)?

To deliver a continuous flow of air pressure to keep the airway open

To reduce daytime sleepiness

To improve sleep quality

To promote weight loss

Answer and Explanation

The Correct Answer is A

A. Delivering a continuous flow of air pressure to keep the airway open is correct. CPAP (Continuous Positive Airway Pressure) prevents airway collapse during sleep, allowing for uninterrupted breathing and oxygenation.
B. Reducing daytime sleepiness is a benefit of CPAP use, but it is not its primary purpose—it is a secondary effect of improved oxygenation and sleep continuity.
C. Improving sleep quality also occurs with CPAP therapy, but this is an outcome rather than the primary purpose.
D. Promoting weight loss is not the function of CPAP therapy, though weight loss can help reduce OSA severity.
