Erythrocyte transfusion

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."

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:

${\text{Increase of hemoglobin}}=5.43-1.71\times {\text{body surface area}}-0.31\times {\text{initial hemoglobin}}+0.72\times {\text{units transfused}}$

The increase is approximately 1 g/dl in adults.
