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.

Famous quotes containing the words blood and/or substitutes:
“Fit gravefellows you are for Lincoln, Brown
And Douglass and Toussaint. . . all whose rapt eyes
Fashioned a new world in this wilderness.
American earth is richer for your bones;
Our hearts beat prouder for the blood we inherit.”
—Dudley Randall (b. 1914)
“The true artist doesn’t substitute immorality for morality. On the contrary, he always substitutes a finer morality for a grosser one.”
