CPAP is an acronym for which device or therapy?

• A. Controlled positive airway pressure
• B. Constant positive airway pressure
• C. Continuous airway pressure device
• D. Continuous positive airway pressure

Answer: (D)

CPAP stands for Continuous Positive Airway Pressure. The idea behind this term is that a steady level of pressure above the surrounding air (positive pressure) is provided continuously to the airway, helping to keep it open throughout the breathing cycle. The word continuous indicates the pressure is maintained without interruption, rather than being intermittent. Among the options, the exact expansion used in medical practice is Continuous Positive Airway Pressure, which is why it is the best choice. Other options change or omit key elements—Controlled or Constant differ from the standard term, and missing the word “airway” or “positive” alters the meaning of the therapy.
