Claims
- 1. A process for oxygenating human blood and simultaneously removing CO.sub.2 which comprises separating venous blood from a human body by shunting said venous blood prior to its return to the heart, contacting said shunted blood in a contacting zone, with an emulsion, the exterior phase which is liquid at a temperature of from 4.degree. to 35.degree.C and which comprises a C.sub.1 to C.sub.40 fluorinated organic compound, said exterior phase further comprising dissolved oxygen, surrounding aqueous droplets, whereby said oxygen permeates into said blood and the CO.sub.2 in said blood permeates into said aqueous droplets, and returning said blood having increased oxygen content and decreased CO.sub.2 content to said human body.
- 2. The process of claim 1 wherein said contacting takes place at a temperature of from 4.degree. to 35.degree.C.
- 3. The process of claim 1 wherein said aqueous droplets contain a CO.sub.2 absorbent.
- 4. The process of claim 1 wherein said aqueous droplets further comprise a reactant capable of reacting with CO.sub.2.
- 5. The process of claim 4 wherein said reactant comprises sodium carbonate.
- 6. The process of claim 4 wherein said exterior phase comprises a C.sub.1 to C.sub.40 fluorinated organic solvent and a C.sub.5 to C.sub.25 fluorinated surfactant.
- 7. The process of claim 6 wherein said surfactant and said solvent are perfluorinated.
- 8. The process of claim 6 wherein said surfactant contains from 5 to 20 carbons and is selected from the group consisting of fluorinated ethers, esters and carboxylic acids.
