| Blood substitutes | Blood substitutes are used to fill fluid volume and/or carry oxygen and other gases in the cardiovascular system. Substances called perfluorochemicals (PFC) have the ability to carry oxygen and carbon dioxide. Perfluorochemicals will not mix with blood, therefore emulsions must be made by dispersing small drops of PFC in water. This liquid is then mixed with antibiotics, vitamins, nutrients and salts, producing a mixture that contains about 80 different components, and performs many of the vital functions of natural blood. As of 1990, most blood substitutes tended to raise blood pressure. (references) | ||
