Parameters:
(1) gender
(2) body weight in kilograms
(3) height in centimeters
(4) chronological age in years
For normal males:
extracellular volume in liters =
= (0.227 * (body weight)) + 0.916
= (0.797 * (chronological age)) + 0.392
= (0.001 * ((height)^2)) – (0.119 * (height)) + 5.39
= (0.074 * (height)) – 2.9 if height <143.1 cm
= (0.337 * (height)) – 40.6 if height >= 143.1 cm
For normal females:
extracellular volume in liters =
= (0.211 * (body weight)) + 0.989
= (0.691 * (chronological age)) + 0.809
= (0.125 * (height)) – 9.151
= (0.115 * (weight)) + (0.058 * (height)) – 3.856
