Altman and Dittmer reported equations for predicting plasma volume based on age and body weight.
Paramaters:
(1) age in years (from 0 to 90)
(2) weight in kilograms (from 0 to 90)
By Age
LOG10(plasma volume in mL/kg) =
= 1.65352 – (0.00061 * (age in years))
plasma volume in mL/kg =
= 10^(1.65352 – (0.00061 * (age))
plasma volume in mL/kg =
= 45.02 * EXP((-1) * 0.0014 * (age))
By Weight
LOG10(plasma volume in mL/kg) =
= 1.695 – (0.03481 * LOG10(weight in kg))
plasma volume in mL/kg =
= 10^(1.695 – (0.03481 * LOG10(weight in kg))
