Abstract
There is provided a user interface comprising: a. a mask body; b. a sealing cushion connected to the mask body and configured to seal around a patient's nose and/or mouth; wherein the mask body and sealing cushion together define an interior chamber of the user interface; c. a breathing gas delivery inlet provided in the mask body and configured to receive a breathing gas flow from a gas source; and d. at least one non-sealing nasal prong in the interior chamber. The user interface further comprising a breathing gas flow director configured to split the breathing gas flow into two flow paths such that a portion of the breathing gas flow is delivered along a first flow path from the inlet into the interior chamber to pressurise the interior chamber, and such that a portion of the breathing gas flow is delivered along a second flow path from the inlet through the nasal prong.
