Abstract
Described herein are combined active PAP/passive EPAP interface devices to transmit positive air pressure from a PAP source to the user, but provide passive EPAP when the PAP source is disabled. These interface device may continue to provide benefit to the user even if the PAP source becomes disconnected or otherwise fails. The interface devices described herein include a passive EPAP airflow resistor configured to provide expiratory positive airway pressure (“EPAP”). These interface devices may also include quick connects and/or disconnects for releasably connecting to the source of pressurized breathable gas, a quick release for disconnecting from the source of pressurized breathable gas, and an adhesive user interface region that connects the device the user'"'"'s face. Also described are adapter for converting a PAP interface devices into combined active PAP/passive EPAP interface devices, and methods of using these devices.
