Which device is CPAP associated with?

• A. Continuous positive airway pressure
• B. Cardiac pressure and perfusion
• C. Cyclic positive airway pressure
• D. Central airway pressure device

Answer: (A)

CPAP involves delivering a constant positive pressure to the airways so they stay open during the entire breath. This steady pressure helps prevent airway collapse and improves oxygenation without requiring additional inhalation effort. The name itself describes the concept: continuous positive airway pressure.

In this question, the option that matches CPAP is the one that literally says continuous positive airway pressure. The other terms describe different ideas—cardiac pressure and perfusion relates to heart function, cyclic positive airway pressure implies varying pressure rather than a constant level, and central airway pressure device isn’t a standard term and doesn’t convey the continuous aspect of CPAP.
