Overcompensation for mask or mouth leaks when using auto-titrating CPAP (APAP) is MOST likely to result in:

• A. Unnecessarily high pressure
• B. Complex sleep apnea
• C. Increased compliance
• D. pneumothorax

Answer: (A)

When an APAP device encounters a mask or mouth leak, its automatic algorithm may interpret the leak as a sign that the airway needs more pressure to stay open. To “compensate” for the perceived issue and maintain effective therapy, the machine can raise the delivered pressure even though the leak is the real problem, not a true need for higher airway support. That is why overcompensation for leaks tends to produce an unnecessarily high pressure. This excessive pressure can cause discomfort or side effects like aerophagia or nasal dryness, and doesn’t reflect an actual need for more pressure. The other options aren’t the typical result: complex sleep apnea isn’t directly caused by leak compensation, increased compliance would imply better tolerance or usage, and pneumothorax is not a common consequence of APAP pressure adjustments.
