The patient interface (10) of the present invention includes a pair of nasal pillows (28) for delivery of gas. The nasal pillows (28) project from a partition (22) that separates an interior of the patient interface into a first chamber (24) that is configured to receive the nose of a patient when the patient interface is mounted operatively on the face of the patient and into which the nasal pillows (28) project and a second chamber (26) that has a port (30) for delivery of gas to and from the nasal pillows (28) via the second chamber (26).

What is claimed is: 1. A patient interface comprising: an elastomeric member comprising an elastomeric flange configured to surround a nose of a patient, the flange configured to substantially support the patient interface on the face of the patient; a partition that is elastomeric and integral with the member, the partition separating an interior of the member into (i) a first chamber that is formed by the partition and the flange, and that is configured to receive the nose of the patient and (ii) a second chamber that is formed by the partition and the flange; a pair of nasal pillows integral with the partition and projecting therefrom into the first chamber for at least partial insertion into nostrils of the patient when the patient interface is mounted operatively on the face of the patient, wherein the nasal pillows communicate the second chamber with the nostrils of the patient; and a port integral with the member in fluid communication with the second chamber for delivery of gas to and from the patient via the second chamber and the nasal pillows. 2. The patient interface of claim 1, further including means integral with each nasal pillow and with the partition for moveably coupling the nasal pillow to the partition. 3. The patient interface of claim 2, wherein each means for moveably coupling biases its corresponding nasal pillow into one of the nostrils of the patient when the patient interface is mounted operatively on the face of the patient. 4. The patient interface of claim 1, wherein each nasal pillow has an opening at an apex thereof. 5. The patient interface of claim 1, further comprising a cushion disposed on a portion of the flange that contacts the face of the patient when the patient interface is mounted operatively on the face of the patient. 6. The patient interface of claim 5, wherein the cushion comprises one or both of a portion of the flange at the periphery of the flange that flairs outwardly away from the first chamber and/or a portion of the flange that rolls inwardly into the first chamber. 7. A patient interface comprising: an elastomeric member defining an interior space, the member comprising an elastomeric flange configured to surround a nose of a patient, the flange configured to substantially support the patient interface on the face of the patient; means for dividing the interior of the member into (i) a first chamber that is formed by the flange and the means for dividing, and that is configured to receive the nose of the patient and (ii) a second chamber that is formed by the flange and the means for dividing, wherein the means for dividing is elastomeric; means projecting from the dividing means into the first chamber for delivery of gas to and from at least one nostril of the patient, wherein the means for delivery of gas communicates the second chamber with the nostrils of the patient; and means in fluid communication with the second chamber for delivery of the gas to and from the patient via the second chamber and the delivery means. 8. The patient interface of claim 7, further including means for biasing the delivery means toward the at least one nostril of the patient when the patient interface is mounted operatively on the face of the patient with the nose of the patient in the first chamber. 9. The patient interface of claim 8, wherein the biasing means biases the delivery means into fluid tight relation with the at least one nostril of the patient. 10. The patient interface of claim 7, wherein the delivery means forms a fluid tight seal with the at least one nostril of the patient. 11. The patient interface of claim 7, further comprising a cushion disposed on a portion of the flange that contacts the face of the patient when the patient interface is mounted operatively on the face of the patient with the nose of the patient in the first chamber. 12. The patient interface of claim 11, wherein the cushion forms a fluid tight seal with the face of the patient when the patient interface is mounted operatively on the face of the patient. 13. The patient interface of claim 11, wherein the cushion comprises a portion of the flange at the periphery of the flange that flares outwardly away from the first chamber. 14. The patient interface of claim 11, wherein the cushion comprises a portion of the flange formed at the periphery of the flange that rolls inwardly into the first chamber. 15. The patient interface of claim 7, wherein the delivery means includes a pair of dome-shaped structures that extend into the first chamber, each dome-shaped structure having an opening at an apex thereof for the passage of gas. 16. The patient interface of claim 7, wherein the member and the means for dividing are formed from a single niece of elastomeric material. 17. A patient interface comprising: an elastomeric member comprising an elastomeric flange configured to surround the nose of a patient, the flange configured to substantially support the patient interface on the face of the patient; at least one nasal pillow extending from the member to contact at least a portion of the patient's nasal region; a port integral with the member in fluid communication with the nasal pillows; and a collar formed from a rigid material, the collar being configured to be engaged by an apparatus that holds the collar in position with respect to the head of the patient, the collar being removably mated with the member so as to hold the member in place on the face of the patient if the collar is held in position with respect to the head of the patient. 18. The patient interface as recited in claim 17, wherein the nasal pillow abuts the patient's nose. 19. The patient interface of claim 17, wherein the nasal pillow extends at least partially into a nostril of a patient. 20. The patient interface of claim 17, further comprising a cushion disposed on a portion of the flange that contacts the face of the patient when the patient interface is mounted operatively on the face of the patient. 21. The patient interface of claim 17, wherein the cushion comprises one or both of a portion of the flange that flairs outwardly away from the first chamber and/or a portion of the flange that rolls inwardly. 22. The patient interface of claim 17, wherein if the collar is mated with the member, the collar surrounds the port. 23. The patient interface of claim 14, wherein the member and the partition are formed entirely from a single piece of elastomeric material. 24. The patient interface of claim 23, wherein the member is configured to removably mate with a collar formed from a rigid material, the collar being configured to hold the member in place on the face of the patient. 25. The patient interface of claim 16, wherein the member is configured to removably mate with a collar formed from a rigid material, the collar being configured to hold the member in place on the face of the patient.
