Abstract
A patient interface and a patient interface system comprise a responsive material and a method for preventing the formation of red marks due to wearing a patient interface that is pressing against the skin of a patient for a longer time and/or for reducing air leakages of the patient interface that may result from an unintended shift of the patient interface on the patient's face. The responsive material is configured for alternating the pressure exerted by the cushion element on the patient and/or the area on the patient where the pressure is exerted by the cushion element in response to a physical quantity acting on the responsive material. The formation of red marks and of air leakages can be reduced or even avoided by means of the responsive material.
