1. A system for applying Cardiopulmonary Resuscitation (CPR) comprising:

an intraoral flexible mouthpiece comprising:

a hollow dome portion comprising a peripheral proximal edge and a distal portion, wherein said hollow dome portion has a peak and extends from said peripheral proximal edge to said distal portion, and wherein said hollow dome portion comprises a central orifice located at the distal portion of said hollow dome portion;

a peripheral flexible sheet flange attached along the entire dome portion peripheral proximal edge;

a tube attached to said central orifice and extending distally therefrom;

wherein said peripheral flexible sheet flange has a distal side and a proximal side and is configured to be placed in the mouth between the teeth and gums that engage the peripheral flexible sheet flange proximal side and the lips and cheeks that engage the peripheral flexible sheet flange distal side, wherein said peripheral flexible sheet flange is configured to be placed in a direction parallel to the teeth, wherein the dome shaped portion is configured to protrude outwardly in a distal direction out of the mouth;

wherein the peak of the dome portion is at the distal portion of said hollow dome portion and wherein said distal portion is a most distal portion of said dome portion; and

wherein the peripheral flexible sheet flange is in direct contact to the peripheral proximal edge; and

wherein said mouthpiece further comprises an internal flexible corrugated conduit having a distal end and a proximal end wherein said internal flexible corrugated conduit distal end is attached to the central orifice located at the distal portion of the hollow dome portion and extends proximally therefrom; and

an oropharyngeal airway comprising an airway flange, a main body portion and a proximal tip, wherein said airway flange is adapted to sealably connect to the internal flexible corrugated conduit.

2. The system of claim 1 wherein the tube is flexible.

3. The system of claim 1 wherein the tube comprises a resilient portion.

4. The system of claim 3 wherein the resilient portion is a corrugated portion.

5. The system of claim 1 wherein the peripheral flexible sheet flange comprises an edge surrounding said peripheral flexible sheet flange, wherein said peripheral flexible sheet flange edge is curved and/or comprises a thickened portion.

6. The system of claim 1 wherein the proximal end of the internal flexible corrugated conduit comprises a grip handle.

7. The system of claim 1 further comprising a distal flange configured to be placed distally to the lips, wherein said distal flange is attached surrounding a second peripheral portion of the dome portion that is distal to the proximal peripheral edge.

8. The system of claim 1 further comprising a nose clamp attached thereto.

9. The system of claim 8 , wherein the tube comprises a resilient portion;

wherein the resilient portion is a corrugated portion;

and wherein said mouthpiece further comprises a strap connected at a first end to the nose clamp and at a second end to a ring portion configured to encircle the corrugated portion.

10. The system of claim 8 wherein the nose clamp comprises two flaps and a reinforcement member, wherein said reinforcement member comprises a spring force feature that applies pressure on said flaps pushing said flaps one towards the other.

11. The system of claim 10 further comprising two finger grips attached to the two flaps respectively, wherein said two finger grips are attached to the reinforcement member therebetween.

12. The system of claim 8 wherein the nose clamp comprises two longitudinal arms and a reinforcement member connected therebetween, wherein said reinforcement member comprises a spring force feature that applies pressure on said arms pushing said arms one towards the other.

13. The system of claim 12 , wherein the nose clamp's two longitudinal arms comprise edges;

wherein the nose clamp comprises two curved handles extending distally from the nose clamp's two longitudinal arms' edges.

14. The system of claim 13 , wherein the curved handles have a “U” shape comprising second edge portions that are substantially parallel to the arms.

15. The system of claim 1 further comprising:

a gas source coupled to the mouthpiece tube.

16. The system of claim 1 further comprising a gas source coupled to the mouthpiece tube.

17. The system of claim 1 , wherein the peripheral flexible sheet flange is approximately perpendicular to the proximal peripheral edge of the dome shaped portion.

18. A method for treating an unconscious patient comprising:

a) inserting the system of claim 1 into a patient's mouth;

b) connecting the tube to a gas source;

c) applying CPR using the gas source.

19. A method for treating an unconscious patient comprising:

a) connecting the corrugated conduit of the system of claim 1 to the oropharyngeal airway flange;

b) inserting the oropharyngeal airway into the patient;

c) inserting and fitting said mouthpiece into a patient's mouth;

d) connecting the tube to a gas source; and

e) applying CPR using the gas source.

20. A system for applying Cardiopulmonary Resuscitation (CPR) comprising:

an intraoral flexible mouthpiece comprising:

a hollow dome portion comprising a peripheral proximal edge and a distal portion, wherein said hollow dome portion has a peak and extends from said peripheral proximal edge to said distal portion, and wherein said hollow dome portion comprises a central orifice located at the distal portion of said hollow dome portion;

a peripheral flexible sheet flange attached along the entire dome portion peripheral proximal edge;

a tube attached to said central orifice and extending distally therefrom;

wherein said peripheral flexible sheet flange has a distal side and a proximal side and is configured to be placed in the mouth between the teeth and gums that engage the peripheral flexible sheet flange proximal side and the lips and cheeks that engage the peripheral flexible sheet flange distal side, wherein said peripheral flexible sheet flange is configured to be placed in a direction parallel to the teeth, wherein the dome shaped portion is configured to protrude outwardly in a distal direction out of the mouth;

wherein the peak of the dome portion is at the distal portion of said hollow dome portion and wherein said distal portion is a most distal portion of said dome portion; and

wherein the peripheral flexible sheet flange is in direct contact to the peripheral proximal edge; and

wherein said mouthpiece further comprises a distal flange configured to be placed distally to the lips, wherein said distal flange is attached surrounding a second peripheral portion of the dome portion that is distal to the proximal peripheral edge such that a channel is formed on said dome portion, bounded by the peripheral flexible sheet flange, the distal flange and the dome portion that they are attached to; and

an oropharyngeal airway comprising an airway flange, a main body portion and a proximal tip, wherein said airway flange is adapted to sealably connect to an internal flexible corrugated conduit of the mouthpiece.
