A pad assembly for use with a gas delivery mask for delivering a flow of gas to an airway of a patient is described. The pad assembly includes an outer casing and a support element. The outer cashing has a housing portion and a mounting portion. The housing portion has a first wall and a second wall defining a hollow cavity therebetween. The first wall is structured to engage a portion of the patient, and the mounting portion is structured to couple the outer casing to the patient interface device. The support element is disposed substantially within the cavity of the outer casing.

The pad assembly of claim 1, wherein the support element comprises an open cell foam material. 4. The pad assembly of claim 1, wherein the support element comprises a closed cell foam material. 5. The pad assembly of claim 1, wherein the outer casing is formed from a silicone or thermoplastic elastomer material. 6. A patient interface device comprising: a mask shell having a patient side and an outer side opposite the patient side adapted for receiving a flow of gas;a seal member having a first end portion adapted to contact a first area of a patient's face to form a seal therewith and a second end portion opposite the first end portion, the second end portion coupled to the mask shell; anda support member coupled to the mask shell, the support member having a pad assembly comprising:an outer casing having a housing portion and a mounting portion formed as a unitary member made of a flexible material having a hardness of about 20 to 40 Shore A, the housing portion having a first wall and a second wall defining a hollow cavity therebetween, the first wall being structured to engage a portion of the patient, and the mounting portion being structured to couple the outer casing to the support member, the mounting portion having a first side and an opposite second side, wherein the first side and the second side form an internal edge of the mounting portion defining an opening through the mounting portion, wherein the second wall of the housing portion is directly coupled to and extends directly from the second side of the mounting portion at the internal edge, and wherein the first side of the mounting portion comprises a coupling mechanism extending therefrom in a direction away from the housing portion, the coupling mechanism being structured to couple the pad assembly to the support member, anda support element disposed substantially within the cavity of the outer casing, wherein the opening is structured to flex and receive the support element therethrough for disposing the support element in the cavity by flexing of the mounting portion. 7. The patient interface device of claim 6, wherein the first wall of the housing portion is generally curved and wherein the second wall of the housing portion is generally curved a greater amount than the first wall. 8. The patient interface device of claim 6, wherein the support element comprises an open cell foam material. 9. The patient interface device of claim 6, wherein the support element comprises a closed cell foam material. 10. The patient interface device of claim 6, wherein the outer casing is formed from a silicone or thermoplastic elastomer material. 11. A method of providing a customizable pad assembly for use with a patient interface device for delivering a flow of gas to an airway of a patient, the method comprising: providing an outer casing having a housing portion and a mounting portion formed as a unitary member made of a flexible material having a hardness of about 20 to 40 Shore A, the housing portion having a first wall and a second wall defining a hollow cavity therebetween, the first wall being structured to engage a portion of the patient, and the mounting portion being structured to couple the outer casing to the patient interface device, the mounting portion having a first side and an opposite second side, wherein the first side and the second side form an internal edge of the mounting portion defining an opening through the mounting portion. wherein the second wall of the housing portion is directly coupled to and directly extends from the second side of the mounting portion at the internal edge, and wherein the first side of the mounting portion comprises a coupling mechanism extending therefrom in a direction away from the housing portion, the coupling mechanism being structured to couple the pad assembly to the patient interface device; andproviding a plurality of support elements, each support element being disposable substantially within the cavity of the outer casing, wherein the opening structured to flex and receive each of the support elements therethrough for disposing each of the support elements in the cavity by flexing of the mounting portion. 12. The method of claim 11, wherein providing a plurality of support elements comprises providing a plurality of support elements of varying density. 13. The method of claim 11, wherein providing a plurality of support elements comprises providing a plurality of support elements of varying softness.
