Abstract
A noise-suppressing gas exhaust system for a gas delivery mask is provided. The system may include a face mask, an arm assembly, and a gas exhaust member. The face mask may be configured to interface with a subject's face. The arm assembly may be configured to support the face mask. The gas exhaust member may be coupled to the arm assembly and may include a single gas passageway extending therethrough. The gas passageway may extend from a first opening formed in a first side of the gas exhaust member to a second opening formed in a second side of the gas exhaust member. The first opening may have a cross-sectional area of about 0.01 square inches to about 0.03 square inches, and the second opening may have a substantially larger cross-sectional area than the cross-sectional area of the first opening.
