Continuous positive airway pressure (CPAP) is useful in the management of the patient with obstructive sleep apnea because it:
a. pushes air into and out of the lungs like a mechanical ventilator.

CPAP prevents the collapse of the hypotonic upper airway tissues. It is standard treatment in a patient with obstructive sleep apnea. The CPAP is delivered to the patient through a nasal (or full face) mask. CPAP does not breathe for a patient like a mechanical ventilator does.
