Notes
  • Although the 2022 race-neutral GLI equations accept ages from 3 to 95 years, in practice, measuring PFTs in children younger than 5 years may be challenging.
  • For more information on PFT reference equations, refer to UpToDate topic reviews on selecting reference values for PFTs.
  • For most accurate calculation, input fractional ages where possible, especially for young individuals.
  • The Predicted FEV1/FVC ratio is population based and calculated independently from the FEV1 and FVC. Therefore, there may be minor differences from the predicted value shown here and the value calculated from simple division of the predicted FEV1 by predicted FVC.
  • PFT: pulmonary function test; GLI: Global Lung Function Initiative; FEV1: forced expiratory volume at 1 second; FVC: forced vital capacity; LLN: lower limit of normal; ULN: upper limit of normal.

 
Equations used
 
Measured values
FEV1/FVC ratio = Measured FEV1 / Measured FVC
Predicted values
Female FEV1 = e(-10.901689 + (2.385928 * ln(Height)) - (0.076386 * ln(Age)) + M spline)
Female FVC = e(-12.055901 + (2.621579 * ln(Height)) - (0.035975 * ln(Age)) + M spline)
Female FEV1/FVC = e(0.9189568 - (0.1840671 * ln(Height)) - (0.0461306 * ln(Age)) + M spline)
Male FEV1 = e(-11.399108 + (2.462664 * ln(Height)) - (0.011394 * ln(Age)) + M spline)
Male FVC = e(-12.629131 + (2.727421 * ln(Height)) + (0.009174 * ln(Age)) + M spline)
Male FEV1/FVC = e(1.022608 - (0.218592 * ln(Height)) - (0.027586 * ln(Age)) + M spline)
Percent predicted values
FEV1 percent predicted = 100 * Measured FEV1 / Predicted FEV1
FVC percent predicted = 100 * Measured FVC / Predicted FVC
FEV1/FVC percent predicted = 100 * Measured FEV1/FVC ratio / Predicted FEV1/FVC ratio
Z-score calculation
Z-score = ((Measurement/M)L - 1) / (L * S)
LMS values for female FEV1 Z-score
L = 1.21388
M = Predicted FEV1
S = e(-2.364047 + 0.129402 * ln(Age) + S spline)
LMS values for female FVC Z-score
L = 0.899
M = Predicted FVC
S = e(-2.310148 + 0.120428 * ln(Age) + S spline)
LMS values for female FEV1/FVC ratio Z-score
L = 6.6490 - 0.9920 * ln(Age)
M = Predicted FEV1/FVC ratio
S = e(-3.171582 + 0.144358 * ln(Age) + S spline)
LMS values for male FEV1 Z-score
L = 1.22703
M = Predicted FEV1
S = e(-2.256278 + 0.080729 * ln(Age) + S spline)
LMS values for male FVC Z-score
L = 0.9346
M = Predicted FVC
S = e(-2.195595 + 0.068466 * ln(Age) + S spline)
LMS values for male FEV1/FVC ratio Z-score
L = 3.8243 - 0.3328 * ln(Age)
M = Predicted FEV1/FVC ratio
S = e(-2.882025 + 0.068889 * ln(Age) + S spline)

 

 
Calculation details and variables
  • Age-based M and S spline coefficients are listed in the tables below.
  • Linear interpolation is used to obtain M and S spline values between the listed ages.
  • The lower and upper limits of normal PFTs are calculated using the Z-score equation, where Z-score is set to -1.645 for the LLN and 1.645 for the ULN.
