摘要：
A headgear for use with a patient interface for delivering a flow of breathable gas to a patient includes at least a strap (741) adapted to position the patient interface in sealing engagement with the patient's airways. The strap is constructed from an elastomer and a first side of the strap includes a first region (215) on a portion of its surface that is textured to reduce friction with objects contacting the strap. A textured surface coating for a portion of an elastomer strap included in a headgear system is adapted to contact the skin of a patient, when in use, and the coating has a Ra value greater than zero. A vent (500) for use with a patient interface for delivering a flow of breathable gas to a patient includes a plurality of rises (580) and runs (570) in a stepped arrangement； and a plurality of holes (510) in the stepped arrangement for the venting of gas.
