Abstract

A mask for use with the administration of CPAP therapy includes a mask body for connection with a supply of breathable gas pressurized above ambient; and a compliant patient contacting element including a multilayered cushioning interface. The interface has an interior layer and an exterior layer provided in spaced relation to the interior layer when the mask is not in use. The exterior layer is elastically and resiliently movable towards and away the interior layer in use. Only the exterior layer forms a contacting seal with the patient in use.
