The blood volume can be estimated from the body surface area.
estimated blood volume (EBV) in liters in males =
= ((3.29 * (body surface area in square meters)) - 1.229)
estimated blood volume (EBV) in liters in females =
= ((3.47 * (body surface area in square meters)) - 1.954)
A variant equation to this is (Smetannikov 1996) :
estimated blood volume (EBV) in liters in males =
= ((0.0236 * ((body height in cm) ^ 0.725) * ((body weight in kg) ^ 0.425)) - 1.229)
estimated blood volume (EBV) in liters in females =
= ((0.0248 * ((body height in cm) ^ 0.725) * ((body weight in kg) ^ 0.425)) - 1.954)
which incorporates the relation:
body surface area in square meters =
= ((weight in kg)^(0.425)) * ((height in cm)^(0.725)) * (0.007184)
Alternative equations:
blood volumes in males in mL =
= 2740 mL per meter squared BSA
blood volumes in females in mL =
= 2370 mL per meter squared BSA
