Claim 15:
16. A patient interface for providing respiratory support to a patient, the patient interface comprising:
a nasal interface having an inlet and an outlet;
a single gas conduit in communication with the inlet of the nasal interface and configured to deliver a gases flow to the outlet of the nasal interface, wherein the single gas conduit comprises a collapsible portion positioned so as to be located over a cheek region of the patient, wherein collapsing the collapsible portion causes the patient interface to transition between a first configuration and a second configuration when a face mask or oral mask is placed over the nasal interface by a user such that a seal region of the face mask or the oral mask contacts the collapsible portion to cause the transition;
wherein the first configuration allows the gases flow to pass through the nasal interface and to the patient; and
wherein the second configuration reduces or stops the gases flow from passing through the nasal interface to the patient.
