WebA perfluorocarbon emulsion has been tested at two concentrations (40 and 80 g/l) on plasma and whole blood viscosity in the presence of human albumin, hydroxyethyl starch, or modified fluid gelatine [ 20 ]. Addition of perfluorocarbon, even at low, i.e. clinically used concentrations, to volume expanders resulted in increased blood viscosity. WebSep 13, 2024 · The perfluorocarbon composition may comprise a dispersion (e.g., emulsion of nanodroplets) having an surfactant/emulsifier content (e.g., phospholipids and any additional cosurfactants) that results in a stable emulsion. Perfluorocarbon dispersions are well known in the art and the surfactant content may generally be any amount that is …
Perfluorocarbon emulsions are emulsions containing either bubbles or droplets which have perfluorocarbons inside them. Some of them are commonly used in medicine as ultrasound contrast agents, and others have been studied for use as oxygen therapeutics. See more The most common use of perfluorocarbon emulsions is as ultrasound contrast agents. In this application, microscopic bubbles containing perfluorocarbon gas are injected intravenously and flow through the … See more Other perfluorocarbon emulsions have been tested as oxygen therapeutics.
