Estimated blood volume per kg

Blood volume can be estimated as approximately 70 mL/kg for adults, 80 mL/kg in children and 100 mL/kg in neonates. Red cell transfusion is usually required when 30–40% of blood volume is lost (1500 mL in a 70 kg male) and more than 40% blood volume loss (1500 to 2000 mL) is life threatening and requires immediate transfusion.(2)
