Indication for transfusion of packed red cells depending on Hb concentration, medical history, and clinical findings*

Hb (g/dL; mmoL/L)	Clinical decision	Transfusion indicated?
≤ 6 g/dL or ≤ 3.7 mmoL/L	Independent of whether cardiovascular risk factors or signs of anemic hypoxia are present	Yes
>6 and ≤ 8 g/dL or >3.7 and ≤ 5 mmoL/L	Neither cardiovascular risk factors nor signs of anemic hypoxia present	No
>6 and ≤ 8 g/dL or >3.7 and ≤ 5 mmoL/L	Either cardiovascular risk factors or signs of anemic hypoxia present	Yes
>8 and ≤ 10 g/dL or >5 and ≤ 6.2 mmoL/L	Signs of anemic hypoxia present	Yes (weak evidence!)
>10 g/dL or >6.2 mmoL/L	Independent of whether cardiovascular risk factors or signs of anemic hypoxia are present	No(except in isolated cases)
