Question: is bipap for oxygenation or ventilation?
Answer: The Difference Between CPAP & BiPAP 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.
