Abstract
A conduit with a collapsible portion, and a nasal interface for providing a flow of gases to a user, is described. The interface comprises a manifold and at least one nasal prong or an outlet extending from the manifold to be received by a user's nare. A side member extends from each side of the manifold, each side member comprising a collapsible portion comprising a lumen. In an open configuration the lumen remains open and in a closed configuration the collapsible portion is pinched or flattened to occlude or substantially occlude the lumen. At least one of the side members is a conduit for a flow of gases from an inlet of the patient interface to the manifold.
