Abstract

A patient interface can have features improving the comfort of use by reducing the perceived pressure of a nose-contacting cushion of the patient interface, against the nose. The patient interface can have rigid headgear connection elements connectable to a frame of the respiratory interface. The rigid headgear connection elements can be shaped to reduce the force of the cushion against the nose. Headgear for a patient interface can also have features improving the stability of headgear of the head. The headgear can have a relatively framework and a relatively pliable overlay covering the framework. The rigid framework can have apertures defining a front portion to be positioned below or near the cheekbones, rear portion to be positioned over the sides of the head around the ears, and a top portion to extend upward along the head towards the crown.
