CPAP differs from bilevel positive airway pressure (BiPAP) where the pressure delivered differs based on whether the patient is inhaling or exhaling. ... The application of CPAP maintains PEEP, can decrease atelectasis, increases the surface area of the alveolus, improves V/Q matching, and hence, improves oxygenation

Is CPAP a ventilation or oxygenation?
CPAP provides oxygenation but not ventilation, which is the actual movement of air into the lungs. CPAP augments ventilation, which should qualify it as a form of NPPV. For the purpose of this discussion, CPAP and BiPAP will both be considered as forms of NPPV. Jan 31, 2008
How does CPAP reduce work of breathing?
Mask CPAP works by assisting spontaneous ventilation and gas exchange. By maintaining a continuous positive airway pressure, CPAP recruits closed (atelectatic) alveoli and increases transpulmonary pressure and thus increases functional residual capacity (FRC) resulting in improved oxygenation.
