In medicine, erythrocyte transfusion or red blood cell transfusion is the "transfer of erythrocytes from a donor to a recipient or reinfusion to the donor."[1]
Effect
Each unit of packed cells is 300 mL, containing 200 mL of red cells. The equation for predicting the rise in hemoglobin (g/dl) in adults from a transfusion is:[2]
The increase is approximately 1 g/dl in adults.[3]
Adverse effects
