Which term denotes a therapy that delivers air pressure to keep the airway open during sleep?

• A. Positive Air Pressure
• B. Positive Airway Pressure
• C. Partial Airway Pressure
• D. Pulmonary Air Pressure

Answer: (B)

Positive Airway Pressure therapy delivers air pressure through a mask to keep the airway open during sleep. This term emphasizes that the pressure is used to maintain patency of the airway, which is the core approach in treating obstructive sleep apnea with devices like CPAP, APAP, and BiPAP. The other options aren’t standard terminology for this therapy: “Positive Air Pressure” is too generic and doesn’t specify the airway, “Partial Airway Pressure” isn’t a recognized term, and “Pulmonary Air Pressure” refers to pressures inside the lungs rather than a therapeutic method to prevent airway collapse.
