Note: Predicted FVC should be "race corrected". If the predicted FVC is not already race corrected it should be reduced 12% for blacks or african americans and 15% for asians (multiply the predicted FVC*0.88 or 0.85).
What %Predicted is the FVC?
(Example: if the FVC is 3.86 Liters and the predicted FVC is 4.14 Liters the equation would be 3.86/4.14*100=).
HERE ARE THE LOWER LIMITS OF NORMAL (LLN) FOR FVC
MALES:
Age 6-11: 74.9% predicted
Age 12-24: 79.8% predicted
Age 25-39: 81.1% predicted
Age 40-84: 73.4% predicted
FEMALES:
Age 6-10: 73.0% predicted
Age 11-19: 74.9% predicted
Age 20-39: 76.9% predicted
Age 40-69: 75.2% predicted
Age 70-87: 71.8% predicted
