What is claimed is:

1. A conduit assembly (18, 50) adapted to deliver a flow of breathing gas to an airway of user comprising:
a first flexible segment (34a, 52a, 84a) having a first end portion, a second end portion, and a first lumen defined therein from the first end portion to the second end portion;
a second flexible segment (34b, 52b, 84b) having a third end portion, a fourth end portion, and a second lumen defined therein from the third end portion to the fourth end portion; and
a first swivel connector (36a, 54, 86a) adapted to be coupled to the second end portion of the first segment and the third end portion of the second segment such that the first segment is rotatable relative the second segment.

2. The conduit assembly of claim 1, wherein the first end portion of the first segment is adapted to be coupled to an outlet of a pressure support device (12).

3. The conduit assembly of claim 1, wherein the fourth end portion of the second segment is adapted to be coupled to a patient interface assembly (28).

4. The conduit assembly of claim 3, wherein the fourth end portion of the second segment is adapted to be coupled to a coupling member (33) associated with the patient interface assembly.

5. The conduit assembly of claim 3, wherein the fourth end portion of the second segment is rotatably coupled to the patient interface assembly.

6. The conduit assembly of claim 1, wherein the first segment and the second segment include a flexible member (56) and a helical support (60) disposed around the flexible member.

7. The conduit assembly of claim 1, wherein the swivel connector includes:
a first portion (66) rigidly coupled to the second end portion of the first segment, and
a second portion (968) rigidly coupled to the third end portion of the second segment, wherein the first portion is rotatably coupled to the second portion.

8. The conduit assembly of claim 1, further comprising a heating element associated with the first segment, the second segment, or both.

9. The conduit assembly of claim 8, wherein the heading element comprises a heating wire disposed in the first lumen, the second lumen, or both.

10. The conduit assembly of claim 3, wherein the patient interface assembly comprises:
a shell having a first side and a second side;
a coupling member coupled to the first side of the shell; and
a cushion coupled to the second side of the shell, and wherein the second end portion of the conduit assembly is coupled to the coupling member.

11. The conduit assembly of claim 10, wherein the coupling member is rotatably coupled to the shell, the fourth end portion of the second segment assembly is rotatably coupled to the coupling member, or both.

12. The conduit assembly of claim 10, wherein the swivel connector includes:
a first portion (66) rigidly coupled to the second end portion of the first conduit, and
a second portion (68) rigidly coupled to the third end portion of the second conduit, wherein the first portion is rotatably coupled to the second portion.

13. The conduit assembly of claim 10, further comprising a humidifier (14) chamber having an humidifier inlet and a humidifier outlet, wherein the humidifier inlet is operatively coupled to an outlet of the housing for a pressure support device (12), and wherein the humidifier outlet is operatively coupled to the first end portion of the conduit assembly.
