I was diagnosed with mild COPD a year ago. I've just had my third spirometry test. My FEV1 is still in the normal ranges but has declined by 6% over a years time. My FVC has declined by 12% over a years time but still in the normal ranges also. I brought up this decline to my nurse and she stated that the only number they look at is the FEV1/FVC number which has remained the same over a years time. Is this accurate? Should this be the only number to consider in these tests? I was under the impression that any decline in FEV and FVC was not good. Even if in the normal ranges. Thanks in advance for any help anyone can give me.
