测定了O2和CO2在全氟三丁胺和全氟丁基全氟四氢呋喃两种氟碳化合物中的溶解度和扩散系数。的溶解度系数和扩散系数的纯形式的碳氟化合物的O2的降低分压的O2（PO 2），但溶解度系数和扩散系数的CO2是独立的其分压。O2在乳化形式的氟碳化合物中的溶解度和扩散遵循纯氟碳化合物中O2行为的预期模式。在O2和碳氟化合物之间可能存在物理和/或化学相互作用;这种相互作用在低于150 mm Hg的分压下更明显。氟碳乳剂中氧含量与全血中氧含量的比较表明，在PO_2为760 mm Hg时，氟碳乳剂中的氧含量约为全血中氧含量的1/2，但在PO_2为50-150 mm Hg时，氟碳乳剂中的氧含量降低至低于全血中氧含量的1/10。
The solubility and diffusion coefficients of O2 and CO2 were measured in the pure and emulsified of 2 fluorocarbons, perfluorotributylamine and perfluorobutyl perfluorotetrahydrofuran. The solubility coefficient and the diffusivity of O2 in the pure form of the fluorocarbons decreased with decreasing partial pressure of O2 (PO2), but the solubility coefficient and the diffusivity of CO2 were independent of its partial pressure. The solubility and diffusion of O2 in the emulsified form of the fluorocarbons followed the pattern expected from the behavior of O2 in the pure fluorocarbon. A physical and/or chemical interaction probably exists between O2 and the fluorocarbons; this interaction is more pronounced at partial pressures below 150 mm Hg. Comparisons of the O2 content in the fluorocarbon emulsions with that in whole blood show that PO2 of 760 mm Hg, the O2 content in the fluorocarbon emulsions is approximately 1/2 that in whole blood, but at PO2 of 50-150 mm Hg, the O2 content in the emulsions decreases to values which are less than 1/10 that of whole blood.
