Abstract
A nasal mask for delivering gas to a mammalian nasal passage includes a body portion including an inlet opening and an outlet opening as well as a facial contact portion having an opening in communication with the outlet opening and a shroud positioned over the facial contact portion opening, wherein the shroud expands to contact the face of a user when gas is delivered through the inlet opening. A method for delivering gas includes identifying a user having a mammalian nasal passage to wear a nasal mask, and preparing a facial contact portion. The facial contact portion is placed on the user's face to contour a facial contact surface to the user's face and the facial contact portion is set. The facial contact portion is attached to a gas delivery system; and gas is delivered to the mammalian nasal passage through the gas delivery system via the facial contact portion.
