Abstract

A blood substitute employs combinations of fluoro or perfluorochemicals capable in the presence of emulsifying agents of forming emulsions stable at room temperature and possessing enhanced oxygen carrying capacity; the invention enables preparation of an improved blood substitute, with improved O.sub.2 carrying capacity and stability, as well as lessened anaphylactoid reaction.
