Abstract
A patient interface assembly includes a patient interface configured to deliver breathing gases to the airway of a patient. A headgear is configured to support the patient interface on the head of a patient. The headgear can include a tab on each side configured to overlie the patient's cheek and forming a portion or an entirety of an attachment region for the patient interface. The tab can be angled relative to an adjacent portion of the headgear. In some configurations, the headgear includes a rear portion having a first degree of stretch and/or a front portion having a second degree of stretch. In some configurations, the headgear also includes a chinstrap having a third degree of stretch. In some configurations, the third degree of stretch is greater than the first degree of stretch and the second degree of stretch.
