Use the following equation to calculate your predicted vital capacity. Male VC = (0.052) H – (0.022) A – 3.60 Female VC = (0.041) H – (0.018) A – 2.

1. Use the following equation to calculate your predicted vital capacity.

Male VC = (0.052) H – (0.022) A – 3.60

Female VC = (0.041) H – (0.018) A – 2.69

V= vital capacity in liters

H= height in cm

A= age in years

 To find your height in centimeters multiply your height in inches by 2.54.
