BiPAP is an abbreviation for which term?

• A. Bilevel Positive Airway Pressure
• B. BiPAP Names
• C. Bilevel Positive End-Expiratory Pressure
• D. Bilevel Continuous Positive Airway Pressure

Answer: (A)

BiPAP reflects two levels of positive airway pressure used during breathing. The “Bi” prefix means two, so the device provides a higher pressure during inspiration (IPAP) to help move air into the lungs, and a lower pressure during expiration (EPAP) to keep the airways open. This two-level approach is what sets BiPAP apart from CPAP, which delivers a single, continuous pressure.

That’s why the term expands to Bilevel Positive Airway Pressure. The other options don’t fit: “Names” is not a real expansion, “End-Expiratory Pressure” would refer to PEEP and isn’t part of the BiPAP acronym, and “Continuous” implies one constant pressure rather than two levels.
