Abstract:
1. A breathing arrangement for use between a patient and a structure to deliver a flow of pressurized breathable gas to the patient for treatment of sleep disordered breathing, the breathing arrangement comprising: a ventilation interface defining a gas entry port to be fluidically connected to the structure to deliver the flow of pressurized breathable gas; an oral interface provided to said ventilation interface, the oral interface configured to seal only along an exterior of the patient's mouth when applied to the patient's face; a nasal interface configured to fluidically couple the gas entry port with nares of the patient when the nasal interface is applied to the patient's nose without forming a seal on a nasal bridge region of the patient's face; and headgear connected to at least one of the ventilation interface and the nasal interface so as to maintain the oral interface and the nasal interface in a desired position on the patient's face and maintain a substantially gas-tight seal between the patient's face and the oral interface and the nasal interface, wherein the oral interface includes an elastomeric side wall, and the nasal interface is flexibly connected to and supported along the elastomeric side wall to provide flexibility between the nasal interface and the oral interface and provide for movement and changes in alignment between the nasal interface and the oral interface.
