Question: 1 / 400

Which accessory device might be used to treat sleep apnea?

Bilevel Positive Airway Pressure (BiPAP) device

Continuous Positive Airway Pressure (CPAP) device

A Continuous Positive Airway Pressure (CPAP) device is a primary and widely recognized treatment for obstructive sleep apnea. It works by delivering a steady stream of air through a mask that keeps the airways open during sleep. This constant pressure prevents the airway from collapsing, thus reducing the frequency and severity of apnea events and improving overall sleep quality. The effectiveness of CPAP therapy in alleviating sleep apnea symptoms has made it the standard first-line treatment for this condition.

While other devices like BiPAP and APAP can also be employed in specific cases to manage sleep apnea, CPAP remains the most common and foundational treatment option in clinical practice. An oxygen concentrator, on the other hand, is not typically used specifically to treat sleep apnea but rather serves a different purpose related to managing hypoxemia.
