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.
b. prevents airway collapse.
c. stretches the J receptors in the chest wall to stimulate breathing.
d. delivers a tidal volume breath to the patient.
B
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.
