Abstract
A blood gas control liquid comprises water, 5-40 percent by volume of a water-insoluble perfluorinated compound material that has an oxygen solubility coefficient, at one atmosphere pressure, 25.degree. C., and a volumetric proportion of 15 percent of at least 10 ml O.sub.2 per 100 mL emulsion, 0.25-10 percent by volume of a nonionic, fluorocarbon-based surfactant, a preservative agent and a buffering agent which is substantially non-reactive with said preservative agent. The blood gas control liquid has a pH in the range of 7-8, a partial pressure of carbon dioxide in the range of 15-80 millimeters Hg, and a partial pressure of oxygen in the range of 20-600 mm Hg.
