           This nomogram corresponds to the formulas:
              FEV1 =  0.0347 x Height - 0.0252 x Age - 1.929
               FVC =  0.04315 x Height - 0.02185 x Age - 2.83
             MEF25-75 =  2.918 + 0.0125 x Height - 0.034 x Age

Ratings derived from this table are age adjusted

Whenever the measured parameter is less than 85% of the predicted, Table 1.4 corresponds to the following formulas:

   Impairment rating based on FEV1 = 98-% FEV1 + Impairment rating based on FVC              = 108-% FVC +
   Impairment rating based on MEF25-75 = 98-% MEF  +

50
(% FEV1-90)

100
(%FVC-88.5)
50
(% MEF-90)

When the measured parameter is 85% or more of the predicted, then the impairment rating is defined as NIL

"%FEV1" means measured FEV1 expressed as a percentage of predicted FEV1. "%FVC" means measured FVC expressed as a percentage of predicted FVC.
 "%MEF" means measured MEF25-75    expressed
