Nasal ventilation interface and system

1. A nasal ventilation interface comprising:

a cannula connectable to a source of ventilation gas via at least two ventilation connectors;

at least one reservoir flange coupled to the ventilation connectors and in close proximity with at least one nasal insert;

at least one seal portion positioned on a distal end of the at least one nasal insert;

a central reservoir between the at least one reservoir flange and the nasal insert;

at least one exhaust flange coupled to the central reservoir; and

an exhaust port coupled to the exhaust flange positioned at a midpoint between the at least two ventilation connectors, the exhaust port having a decreasing circumference from a proximal portion towards a distal end of the exhaust port.

2. The ventilation interface according to claim 1 , wherein the exhaust port is configured with an adjustable dial to adjust the aperture of the exhaust port.

3. The ventilation interface according to claim 1 , wherein an interior wall of the exhaust port maintains a substantially constant diameter.

4. The ventilation interface according to claim 1 , further comprising at least one headgear flange.

5. The ventilation interface according to claim 4 , wherein the at least one headgear flange is connected on the outer wall of the cannula.

6. The ventilation interface according to claim 1 , wherein at least one of the reservoir flange, nasal insert, and central reservoir are configured to provide laminar flow.

7. The ventilation interface according to claim 1 wherein the exhaust port has a substantially oval cross section.

8. The ventilation interface according to claim 1 wherein the seal portion has a substantially oval cross section.

9. The nasal ventilation interface according to claim 1 further comprising: means for adjusting an aperture of the exhaust port.

10. A nasal ventilation interface comprising:

a cannula connectable to a source of ventilation gas via at least two ventilation connectors forming a first inflow portion;

a reservoir flange forming a second inflow portion;

at least one nasal insert, the at least one nasal insert forming a third inflow portion and a first outflow portion;

at least one seal portion positioned on a distal end of the at least one nasal insert;

a central reservoir forming a second outflow portion;

at least one exhaust flange forming a third outflow portion; and

an exhaust port positioned at a midpoint between the at least two ventilation connectors forming a fourth outflow portion and a fifth outflow portion, the exhaust port having a decreasing circumference from a proximal portion towards a distal end of the exhaust port.

11. The ventilation interface according to claim 10 , wherein the exhaust port is configured with an adjustable dial to adjust the aperture of the exhaust port.

12. The ventilation interface according to claim 10 , wherein an interior wall of the exhaust port maintains a substantially constant diameter.

13. The ventilation interface according to claim 10 , further comprising at least one headgear flange.

14. The ventilation interface according to claim 13 , wherein teat least one headgear flange is connected to the reservoir outer wall.

15. The ventilation interface according to claim 10 , wherein at least one of the reservoir flange, nasal insert, and central reservoir are configured to provide laminar flow.

16. The ventilation interface according to claim 10 wherein the exhaust port has a substantially oval cross section.

17. The ventilation interface according to claim 10 wherein the seal portion has a substantially oval cross section.
