Abstract
Biocompatible fluorcarbon emulsions having fluorocarbon in concentrations of from 75% weight per volume to 125% weight per volume have small, biocompatible particle size stability through heat sterilization with one emulsifying agent, including phospholipids, in concentrations of from 3% to 7% weight per volume. The single emulsifying agent can be hydrogenated lecithins and synthesized lecithins. Fluorocarbon emulsions having fluorocarbon in concentrations of from 40% weight per volume to 125% weight per volume have stability of partial pressure of oxygen and of partial pressure of carbon dioxide through heat sterilization and storage for extended periods of time after having been oxygenated with dissolved oxygen.
