US 2013/0152935 A1 · System, Method And Ventilation Interface For Providing Pressurized Breathable Gas To The Mouth And Nose Separately

Abstract

In accordance with at least one exemplary embodiment, a ventilation system for providing gas under a first pressure to the nose of a user and second pressure to the mouth of a user is disclosed. A ventilation system can include a flow generator that can be connected to a gas supply tube. The gas supply tube can be in fluid communication with a ventilation interface. At least a portion of the gas supply tube can have a divider within the channel of the tube forming a nasal passageway and an oral passageway. A nasal breathing chamber and an oral breathing chamber can be defined in the ventilation interface. The nasal breathing chamber can be in fluid communication with the nasal passageway. The oral breathing chamber can be in fluid communication with the oral passageway.
