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 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 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 for use with a patient interface for delivering a flow of breathable gas to a patient includes a plurality of rises and runs in a stepped arrangement； and a plurality of holes in the stepped arrangement for the venting of gas.
