ABSTRACT:
In accordance with one embodiment of the present disclosure, an adjustable gas delivery system is provided. The system may include a face mask, an arm apparatus, and a gasket. The face mask may be configured to deliver gas to a subject, and may include a flexible cushion portion configured to interface with the subject's face and a rigid base portion configured to support the cushion portion, the rigid base portion including a gas inlet. The arm apparatus may be configured to deliver gas to the face mask. The arm apparatus may include a gas outlet having a cross-sectional area smaller than a cross-sectional area of the gas inlet of the base portion of the face mask. The gasket may couple the gas outlet of the arm apparatus with the gas inlet of the face mask. The gasket may be flexible such that the orientation of the face mask relative to the arm apparatus is adjustable.
