Addressing Unintentional Leakage When Using Nasal CPAP - Study A

NCT06570616 · Status: RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 100

No results posted yet for this study

Summary

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.

Conditions

Interventions

DEVICE

CPAP (fixed mode)

Patients will undergo strategies to control excessive leakage while using autoCPAP vs. progressively decreasing fixed nasal CPAP. Before randomization, subjects will undergo an autoCPAP titration for 3 days. Subjects will then be randomized to start the protocol with autoCPAP or fixed CPAP and then will switch to the alternative arm.
