There are two main categories of artificial blood :-# Oxygen therapeutics: For artificial blood that carries oxygen
# Volume expanders, for inert blood.
When severe trauma occurs, a serious danger is that blood volume will be reduced to a point where the remaining red blood cells can no longer oxygenate body tissue, which can result in tissue damage or death. Artificial blood solves this by acting as a volume expander, making up for the lost quantity of blood. Because real blood has a substantial capacity for carrying oxygen, so long as volume is retained, even a dilute ratio of real blood to artificial blood can be adequate to keep a person alive.
Heart transplant, bypass and cancer patients would also benefit from having a guaranteed supply of blood on hand for their surgery.The man-made blood would be free of infections that have blighted natural supplies and could be given to almost everyone regardless of blood group.
