Blood Substitutes
A blood substitute (also called artificial blood or blood surrogates) is a substance used to mimic and fulfill some functions of biological blood, usually in the oxygen-carrying sense. It aims to provide an alternative to blood transfusion, which is transferring blood or blood-based products from one person into another.
The main categories of such oxygen-carrying blood substitutes are hemoglobin-based oxygen carriers (HBOC) and perfluorocarbon-based oxygen carriers (PFBOC). Oxygen therapeutics are in clinical trials in the U.S. and Europe, and Hemopure is available in South Africa.
