Blood substitute (also called blood surrogate) is the name for a number of substances that can perform some functions of blood. Blood substitutes are often used in blood transfusions where real blood is not available. Losing a lot of blood can mean there is not enough blood left to keep up the oxygen transfer to certain organs, or the brain. This state is a medical emergency, as it can lead to organ failure and death. Blood substitutes can help in these situations.
