US 2014/0109907 A1 · CPAP INTERFACE AND BACKUP DEVICES

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.

Dependent claims

An adapter device for a PAP interface that connects to a PAP source, the adapter device capable of converting the PAP interface into a combined active PAP/passive EPAP interface that provides passive EPAP when the PAP source is disabled, the device comprising:

a passive EPAP airflow resistor configured to be placed in communication with an airway through the PAP interface to passively inhibit exhalation more than inhalation, wherein the passive EPAP airflow resistor is configured to provide a resistance to exhalation when the PAP source is disabled that is between about 0.001 and about 0.5 cm H2O/(ml/sec) when the resistance is measured at 100 ml/sec.
