PFT Quick Reference
SYSTEMATIC EVALUATION OF PFTs
Jeanne M. Ferrante, M.D.
1. FEV1/FVC
>70%= normal
61-69%= mild obstruction
45-60%= moderate obstruction
< 45%= severe obstruction
2. FEF 25-75 (reflects small airways disease)
>79% predicted= normal
60-79% predicted= mild obstruction
40-59% predicted = moderate obstruction
