Which statement best describes the minimum duration criterion for acceptable PAP titration outcomes in terms of RDI and sleep position?

• A. 5 minutes
• B. 10 minutes
• C. 15 minutes
• D. 20 minutes

Answer: (C)

When interpreting PAP titration results, you must ensure there is enough recorded sleep under therapeutic pressure to reliably judge how well breathing is controlled across different body positions. The residual respiratory disturbance index (RDI) under PAP reflects how often breathing events occur per hour despite treatment. Because sleeping position can change airway mechanics, you need enough data in the relevant positions to see whether the chosen pressure truly keeps the RDI low in each position. That reliability comes from a minimum of 15 minutes of sleep data collected while the patient is using PAP, across the positions tested. Shorter segments may miss recurrent events or positional differences, leading to an inconclusive assessment. Therefore, 15 minutes is the standard minimum duration for deeming a PAP titration outcome acceptable.
