A fluorocarbon emulsion which exhibits reduced pulmonary gas-trapping properties in species-sensitive laboratory animals is disclosed. Additionally, the fluorocarbon component(s) exhibit short organ retention time(s). The emulsion includes an aqueous phase, an emulsifier, and a fluorocarbon (or fluorocarbon composition), having a vapor pressure of less than about 8 torr to reduce pulmonary gas-trapping, and having an organ retention half life of less than about 6 weeks and more preferably less than about 3 to 4 weeks.
