The Total Lung Capacity (TLC) can be predicted in pediatric patients based on height and other physical characteristics.
NOTE: Quanjer et al provides many additional equations for TLC (pages 216s-217s).
Linear Equations Based on Height
TLC in liters for boys 5 to 18 years (Godfrey) =
= (0.065 * (height in cm)) - 5.18
TLC in liters for girls 5 to 18 years (Godfrey) =
= (0.055 * (height in cm)) - 3.95
TLC in liters for boys 4-19 years < 162.6 cm (Rosenthal) =
= (0.0498 * (height in cm)) - 3.828
TLC in liters for boys 4-19 years >= 162.6 cm (Rosenthal) =
= (0.0959 * (height in cm)) - 10.648
TLC in liters for girls 4-19 years (Rosenthal) =
= (-6.8598 * (10^(-7)) * ((height in cm)^4)) + (3.81 * (10^(-4)) * ((height in cm)^3)) - (0.078 * ((height in cm)^2)) + (7.031 * (height in cm)) - 234.08
TLC in liters for patients 4 to 18 years (Weng and Levison) =
= 0.160 * EXP(0.021 * (height in cm))
Exponent of Height
TLC in liters for males (Polgar and Promadhat) =
= (0.0000056 * ((height in cm)^2.67))
TLC in liters for females (Polgar and Promadhat) =
= (0.000004 * ((height in cm)^2.73))
TLC in liters for males 8-16 years (Cotes et al) =
= (1.227 * ((height in meters)^2.80))
TLC in liters for females 8-16 years (Cotes et al) =
= (1.189 * ((height in meters)^2.64))
TLC in milliliters (Helliesen et al) =
= 0.003 * ((height in cm)^2.80)
TLC in liters (Engstrom et al) =
= 4.13 * (10^(-6)) * ((height in cm)^2.73)
