Abstract
A patient interface for use in delivering a flow of a breathing gas to an airway of a patient includes a body that defines a cavity therein that is structured to receive the flow of breathing gas. A first aperture defined in the body is positioned and structured to communicate the flow of breathing gas from the cavity to an airway of the patient. A second aperture defined in the body is sized and configured to provide a pathway between the cavity and an ambient environment in which the body is disposed. The patient interface further includes a restrictor element that is selectively coupled to the body. The restrictor element includes a blocking portion that obstructs at least a portion of the second aperture.
