Abstract
A cushion for use with a patient interface device includes a first end portion, which typically contacts the patient's face when the patient interface device is worn, a second end and/or opposite the first end, which is typically coupled to a portion of the patient interface device, a chamber, which is typically disposed between the first and second end portions, and an orifice. The chamber is structured to receive and store a dampening medium therein; and the orifice, which is in operative communication with the chamber, controls the passage of the dampening medium into and/or out of the chamber. A patient interface device including a mask shell and the cushion is also described.
