What is Claimed is:

1. A nasal mask assembly comprising:
a body member defining a nose receiving cavity, said body member having a first opening defined in a first end and adapted to receive a nose of a patient such that a portion of a nose of such a patient is disposed in said nose receiving cavity and such that a mouth of such a patient remains exposed responsive to said nasal mask assembly being positioned on such a patient, and said body member having a second opening defined in a second end and adapted to receive a supply of breathing gas to communicate such breathing gas to said nose receiving cavity;
a flange associated with said first opening of said body member, said flange being configured and arranged such that a first surface is adapted to overlie a surface of a patient responsive to said nasal mask assembly being positioned on such a patient; and
a first adhesive layer disposed on said first surface of said flange, said first adhesive layer selectively engaging a surface of a patient and maintaining said first surface of said flange in a substantially sealed relation with such a patient so as to adhere said nasal mask assembly to a surface of a patient responsive to said nasal mask assembly being positioned on such a patient.

2. A nasal mask assembly according to claim 1 , wherein said body member is generally frustum shaped with said first opening being defined in a base thereof and said second opening being defined in an apex thereof.

3. A nasal mask assembly according to claim 1, wherein at least one of said body member and said flange is defined by a flexible elastomeric material.

4. A nasal mask assembly according to claim 1 , wherein a configuration of at least one of said first end of said body member and said flange is predefined so as to generally correspond to facial contours of a region surrounding a nose of a population of patients.

5. A nasal mask assembly according to claim 1 , wherein said flange includes a first edge and a second edge, and wherein said first edge of said flange is fixed to an edge of said body member defining said first opening.

6. A nasal mask assembly according to claim 5, wherein a distance between said first edge and said second edge of said flange is greater in a portion of said flange adapted to be positioned proximate to a bridge and a side of a nose of a patient than in a portion of said flange adapted to be positioned proximate a patient's upper lip.

7. A nasal mask assembly according to claim 1, further comprising:
a flexible material layer disposed between said first adhesive layer and said flange; and
a second adhesive layer disposed between said flexible material layer and said flange.

8. A nasal mask assembly according to claim 1, further comprising:
a headgear assembly; and
an attachment assembly associated with at least one of said body member and said flange, said attachment assembly providing at least one contact point for coupling said headgear assembly to said nasal mask assembly.

9. A nasal mask assembly according to claim 1, further comprising a conduit coupled to said second opening such that an interior of said conduit communicates with said nose receiving cavity.

10. A nasal mask assembly according to claim 9, wherein at least one of said body member and said conduit includes an exhaust port defined therein to communicate an interior of an associated one of said nose receiving cavity and an interior of said conduit to atmosphere.

11. A nasal mask assembly according to claim 9, wherein said conduit includes a flexible portion generally proximate to said body member.

12. A nasal mask assembly according to claim 1, further comprising a protective cover layer selectively attachable to said first adhesive layer, said protective cover layer preventing attachment of said first adhesive layer in said substantially sealed relation responsive to said protective cover layer being affixed to said first adhesive layer, and permitting said first adhesive layer to be attached to a patient in said substantially sealed relation responsive to said protective cover layer being removed from said first adhesive layer.

13. A nasal mask assembly according to claim 1 , further comprising an auxiliary attachment assembly comprising:
a substrate having a first side and a second side;
a second adhesive layer disposed on said first side of said substrate; and
a third adhesive layer disposed on said second side of said substrate, said auxiliary attachment assembly being selectively attachable to said first adhesive layer such that said second adhesive layer contacts said first adhesive layer and such that said third adhesive layer is adapted to engages a surface of a patient and maintain said flange in said substantially sealed relation.

14. A system according to claim 1, further comprising a headstrap having a first end portion and a second end portion adapted to attach to one of said body member and said flange.

15. A system for providing breathing gas to a patient, comprising:
a pressure generator that generates a flow of breathing gas;
a conduit coupled to said pressure generator to carry said flow of breathing gas from said pressure generator to a patient; and
a nasal mask assembly comprising:
a body member defining a nose receiving cavity, said body member having a first opening defined in a first end adapted to receive a nose of a patient such that a portion of a nose of such a patient is disposed in said nose receiving cavity and such that a mouth of such a patient remains exposed responsive to said nasal mask assembly being positioned on such a patient, and said body member having a second opening defined in a second end, said second opening being coupled to said conduit to communicate said flow of breathing gas to said nose receiving cavity;

[ 6- a flange associated with said first opening, said flange being configured and arranged such that a first surface is adapted to overlie a surface of a patient
responsive to said nasal mask assembly being positioned on such a patient; and
a first adhesive layer disposed on said first surface of said flange, said first adhesive layer selectively engaging a surface of a patient and maintaining said first surface of said flange in a substantially sealed relation with such a patient so as to adhere said nasal mask assembly to a surface of a patient responsive to said nasal mask assembly being positioned on such a patient.

16. A nasal mask assembly comprising:
nose encapsulating means for encapsulating a nose of a patient such that a portion of a nose of such a patient, including a patient's nostrils, is disposed in an interior of said nose encapsulating means and such that a mouth of such a patient is not disposed in said interior of said nose encapsulating means responsive to nose encapsulating means being positioned on such a patient; and
adhesive means for maintaining said nose encapsulating means in a substantially sealed relation with a surface of a patient responsive to said nasal mask assembly being positioned on such a patient.

17. A nasal mask assembly according to claim 16, further comprising means for providing a supply of breathing gas to said interior of said nose encapsulating means so that said supply of breathing gas enters a patient's nostrils.

18. A nasal mask assembly according to claim 16, further comprising means for exhausting breathing gas from said interior of said nose encapsulating means.

19. A nasal mask assembly according to claim 16, further comprising means for selectively attaching said nose encapsulating means to a head of a patient to provide a secondary constraint to maintain said nose encapsulating means in proximity to a patient.

20. A method of communicating a supply of breathing gas to a patient, comprising:
providing a nasal mask including: a body member defining a nose receiving cavity, said body member having a first opening and a second opening,
a flange associated with said first opening,
an adhesive layer disposed on a first surface of said flange, and
a protective cover layer disposed on said adhesive layer;
removing said protective cover layer to expose said adhesive layer; and
attaching said nasal mask over a nose of a patient such that a portion of a nose of such a patient is disposed in said nose receiving cavity with said adhesive layer
maintaining said flange in a substantially sealed relation with respect to such a patient with a mouth of such a patient remaining exposed.

21. A method according to claim 20, further comprising a step of providing a supply of breathing gas to said nose receiving cavity via said second opening.

22. A method according to claim 21, wherein said nasal mask assembly includes a strap having a first end portion and a second end portion adapted to attach to one of said body member and said flange, further comprising a step of attaching said strap around a head of a patient.
