What are red blood cells used for in transfusions?
Red blood cell transfusions are used to treat hemorrhage and to improve oxygen delivery to tissues. Transfusion of red blood cells should be based on the patient’s clinical condition.
How long do red blood cells from a transfusion last?
The normal daily production of red blood cells (RBC) in a healthy adult is about 0.25 mL/kg and the average lifespan of the cells is about 120 days, whereas that of transfused RBCs is about 50–60 days and can be significantly shorter in the presence of factors reducing their survival.
What are the risks of red blood cell transfusion?
Particular attention will be paid to the two most significant risks: transmission of serious blood-borne infection and the potentially fatal acute immune hemolytic reaction that occurs if patients receive ABO-incompatible red cells. Other significant adverse effects will be discussed briefly.

How do you transfuse packed cells?
The patient may receive plasma, or packed red blood cells, or if there is a need both may be given. After donated blood is collected, the components are separated in a centrifuge, then a small amount of an anticoagulant is added to keep the packed red blood cells from clotting.
What is the difference between blood transfusion and blood infusion?
Infusions essentially refer to when an outside substance is administered directly into the bloodstream, while transfusions refer to when the same substance, just from an outside source, is administered in the same manner.
