THERMODYNAMICALLY-STABLE AQUEOUS PERFLUOROCARBON MICROEMULSION USEFUL AS BLOOD GAS CONTROL OR CALIBRATOR

摘要

A blood gas control or calibrator having an assayed value of p02 and being an emulsion of a perfluorocarbon phase dispersed in a buffered aqueous phase is disclosed. The emulsion is a microemulsion which is thermodynamically stable at room temperature, contains at least 10 weight percent of a perfluorocarbon of high oxygen solubility and contains two surfactants. The primary surfactant is non tonic and water soluble . The secondary surfactant is hydrotropic and is present in an amount sufficient to disorder any water-primary surfactant gels.
