Note: Predicted FEV1 should be "race corrected". If the predicted FEV1 is not already race corrected it should be reduced 12% for blacks or african americans and 15% for asians (multiply the predicted FEV1*0.88 or 0.85).
What %Predicted is the FEV1?
(Example: if the FEV1 is 2.33 Liters and the predicted FEV1 is 2.85 Liters the equation would be 2.33/2.85*100=).
