What is the most common reason for encountering an unacceptable leak value during PAP titration?

• A. Poor mask fit
• B. Inadequate therapist oversight
• C. Patient sleeping position
• D. Low ambient humidity

Answer: (A)

Leak measurement during PAP titration hinges on a good mask seal. An unacceptable leak value shows up when air escapes around the mask edges rather than through the vent, so the device can’t accurately read flow and pressure. The most common cause is poor mask fit—if the mask doesn’t seal well, even normal breaths generate large, unaccounted leakage that disrupts the titration. That’s why the typical fix is to adjust or change the mask size or type, tighten and reposition the mask, and address any mouth breathing or strap issues to achieve a proper seal. The other factors—therapist oversight, sleeping position, or low ambient humidity—do not routinely cause the persistent, unacceptable leaks seen with a bad mask seal.
