The most common reason for changing the PAP interface during titration is:

• A. Sustained desaturations
• B. Low sleep efficiency
• C. Treatment emergent central apneas
• D. Unacceptable leak value

Answer: (D)

During PAP titration, a stable, accurate flow and pressure readout depends on a proper mask seal. When the leak is unacceptable, the device cannot reliably deliver the prescribed pressure or accurately interpret the patient’s breaths, which undermines the whole titration process. Changing the interface to achieve a better seal restores reliable pressure delivery and clean data, making it the most common and effective reason to switch masks during titration. Issues like desaturations, low sleep efficiency, or treatment-emergent central apneas may occur, but they are addressed through other adjustments or investigations rather than primarily by changing the interface.
