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, a pump adapted to deliver a 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, wherein the second inlet is positioned on the mixing chamber in such a way that the second fluid enters the mixing chamber in a generally upward direction. 2. The device, as set forth in claim 1, comprising a control assembly coupled to the pump. 3. The device, as set forth in claim 2, comprising a display coupled to the control assembly. 4. The device, as set forth in claim 1, comprising a fluid delivery apparatus adapted to deliver the mixed fluid to a destination site. 5. The device, as set forth in claim 4, wherein the destination site is located on a patient. 6. The device, as set forth in claim 1, comprising a capillary assembly coupling the gas-fluid supply to the mixer. 7. The device, as set forth in claim 6, wherein the capillary assembly comprises a single capillary. 8. The device, as set forth in claim 6, wherein the capillary assembly comprises a plurality of capillaries. 9. The device of claim 1, wherein the first fluid comprises a blood. 10. The device, as set forth in claim 9, wherein the pump receives the blood from a patient. 11. The device, as set forth in claim 10, wherein the second fluid comprises physiologic saline. 12. The device, as set forth in claim 1, wherein the mixing chamber comprises a substantially cylindrical wall and wherein the first inlet is arranged to direct fluid along a path substantially tangential to the cylindrical wall. 13. The device, as set forth in claim 1, wherein the first inlet is positioned on the mixing chamber in such a way that the first fluid enters the mixing chamber in a direction normal to the flow of the second fluid. 14. The device, as set forth in claim 1, wherein the mixing chamber is pressurizable. 15. The device, as set forth in claim 1, comprising a tube coupling the pump to the mixer, the tube adapted to deliver the first fluid.
