About this trial
Oral unintentional leak is a common side effect of continuous positive airway pressure (CPAP) for obstructive sleep apnea (OSA) treatment. Management of oral unintentional leakage has not been standardized and the effectiveness of potential approaches have not been studied in controlled studies. Higher levels of CPAP are associated with higher leak. In the present study, a sequential approach to control excessive unintentional leak will be tested. In study A, the reduction of therapeutic CPAP level will be tested. In study B, oronasal CPAP will be compared to nasal CPAP with a chinstrap.
Eligibility criteria

Disqualifiers
Patients who experience unintentional leakage from the mask/accessories.
Diagnostic polysomnography examination with a predominance of central apnea;
