An apparatus and method for blood oxygenation are provided. The apparatus advantageously comprises a liquid-to-liquid oxygenation assembly. The liquid-to-liquid oxygenation assembly includes a pressurizable chamber having inlets for a first gas-supersaturated fluid and a second fluid, such as blood. The inlets are advantageously positioned on the mixing chamber in such a way that the first fluid and the second fluid enter the mixing chamber normally to each other to promote mixing and liquid-to-liquid gas transfer. The mixed fluid exits the chamber via an outlet for delivery to a patient.

1. A device for enriching a liquid with a gas comprising:a mixing chamber having a first inlet, a second inlet, and an outlet, wherein the mixing chamber comprises a substantially cylindrical wall and wherein the first inlet is arranged to direct a first fluid along a path substantially tangential to the cylindrical wall; a pump adapted to deliver the first fluid to the mixing chamber via the first inlet; and a gas-supersaturated fluid supply assembly adapted to deliver a second fluid having a liquid phase supersaturated with a gas to the mixing chamber via the second inlet to mix with the first fluid and form a mixed fluid, wherein the mixed fluid exits the mixing chamber through the outlet. 2. The device, as set forth in claim 1, wherein the gas-supersaturated fluid supply assembly is adapted to deliver a second fluid having a liquid phase supersaturated with a gas and a gas phase to the mixing chamber via the second inlet to mix with the first fluid and form a mixed fluid.3. The device, as set forth in claim 2, wherein the gas phase of the second fluid comprises oxygen.4. The device, as set forth in claim 1, wherein the gas is oxygen.5. The device, as set forth in claim 1, wherein the liquid phase of the second fluid comprises physiologic saline.6. The device, as set forth in claim 1, wherein the first fluid comprises blood.7. The device, as set forth in claim 1, wherein the gas is dissolved in the mixed fluid in greater levels than in the first fluid.8. The device, as set forth in claim 1, wherein the mixed fluid comprises hyperoxic blood.9. The device, as set forth in claim 1, wherein the mixed fluid comprises hyperbaric blood.10. The device, as set forth in claim 1, wherein the first inlet is arranged to create a cyclonic flow in the mixing chamber.11. The device, as set forth in claim 1, wherein the second inlet is arranged so that the second fluid enters the chamber in a generally upward direction.12. The device, as set forth in claim 1, wherein the second inlet is arranged so that the second fluid enters the chamber in a direction normal to the initial direction of travel of the first fluid entering the chamber.13. The device, as set forth in claim 1, wherein the mixing chamber is pressurizable.14. The device, as set forth in claim 1, comprising a control assembly coupled to the pump.15. The device, as set forth in claim 14, comprising a display coupled to the control assembly.16. The device, as set forth in claim 1, wherein the pump receives the first fluid from a fluid supply.17. The device, as set forth in claim 1, wherein the pump receives the first fluid from a patient.18. The device, as set forth in claim 1, comprising a fluid delivery apparatus adapted to deliver the mixed fluid to a destination site.19. The device, as set forth in claim 18, wherein the destination site comprises a patient.20. The device, as set forth in claim 1, comprising a tube coupling the pump to mixing chamber, the tube adapted to deliver the first fluid.21. The device, as set forth in claim 1, comprising a capillary assembly coupling the gas-supersaturated fluid supply to the mixing chamber.22. The device, as set forth in claim 21, wherein the capillary assembly comprises a single capillary.23.
