artificial blood

• artificial blood can keep you alive in an emergency
• when someone loses a lot of blood, the heart can still pump the remaining red blood cells around the body, as long as the volume of blood can be topped up
• artificial blood is a blood substitute used to replace the lost volume of blood
• it is safe if no air bubbles get into the blood
• artificial blood may give the patient enough time to produce new blood cells - if not the patient will need a blood transfusion
