What role does CPAP play in the management of obstructive sleep apnea?

In the management of obstructive sleep apnea, Continuous Positive Airway Pressure (CPAP) plays a crucial role by delivering sustained pressure to maintain airway patency. This therapy works by providing a continuous flow of air through a mask, which creates a steady level of pressure that prevents the upper airway from collapsing during sleep. By keeping the airway open, CPAP helps to reduce or eliminate apneas (pauses in breathing) and hypopneas (shallow breathing), ultimately improving the patient's oxygen levels and quality of sleep.

The mechanism of action of CPAP directly addresses the obstructive nature of the condition, as the airway is often blocked or narrowed due to factors such as excess tissue or muscle relaxation during sleep. By ensuring that the airway remains opened, CPAP allows for more effective and uninterrupted breathing, helping to alleviate the symptoms associated with obstructive sleep apnea.

While the other choices address features related to different aspects of respiratory management, they do not accurately reflect the purpose and function of CPAP in this context.
