  • Publication number: 20230050356
    Abstract: The invention relates to a patient interface comprising a plenum chamber, a seal-forming structure, and a positioning and stabilizing structure, as well as the method of operating the patient interface. The patient's interface is configured to leave a patient's mouth uncovered or if the seal-forming structure is configured to seal around a patient's nose and mouth, the patient interface is configured to allow the patient to breath from the ambient in an absence of the flow of pressurized. The positioning and stabilizing structure includes headgear, and the seal-forming structure and at least a portion of the headgear is formed from a one piece construction of textile material. In another embodiment, the seal-forming structure and/or the positioning and stabilizing structure includes an adaptive portion that adjusts based on usage conditions.
