Notes

  • The residual standard deviation (RSD) for FEV1 is 0.38 liters.
  • For FVC, the RSD is 0.38 liters and for the FEV1/FVC Ratio, the RSD is 6.51%.

Equations used


FEV1 = Race * ((0.0395 * Height) - (0.025 * Age) - 2.6 )
 

FVC = Race * ((0.0443 * Height) - (0.026 * Age) - 2.89 )
 

FEV1FVCRatio = 89.1 - (0.19 * Age)
 

Calculation details and variables

  • Equation parameters such as Race, have two or more discrete values that may be used in the calculation. The numbers in the parentheses, e.g. (0.93), represent the values that will be used.
