Where can I obtain a chart listing the predicted (normal) values for FEV1?
1 % of predicted post-bronchodilator
>80% = Mild
50-80% = Moderate
30-50% = Severe
<30% = Very Severe
This is all valuable information but what I am looking for is a chart listing the age/sex and expected FEV1.
I know that according to the GOLD criterion a person has COPD if their actual to predicted FEV1 is <.7 then they have COPD.
I have a spirometer but I am looking for a simple chart that would list normal values.
