Pulmonology Advisor: Sleep specialist Richard J. Castriotta, MD, FCCP, FAASM, answers questions about common side effects of CPAP and recommendations for clinicians.

Of note, the patient-reported leaks were not predicted by leaks reported by the device software. “CPAP devices only record leak flows, whereas the patient’s perception of a leak is a complex phenomenon involving not only the strength of the leak-flow itself but also how it feels on his/her skin/eyes (if the mask is not properly adjusted), and associated noises,” the authors explained.2

In addition, device-reported leaks and apnea hypopnea index were not significantly associated with nonadherence or ESS scores.
