I was wondering...
I have been diagnosed with emphysema , allmost, tree years now, and i have had several PFT done, the last one last week. FEV1 4.03, FVC 5.24, and an index at 77, so very near normal LFT. Beside that, i feel much worse than i did 3 years ago. So it makes question the value of PFT in emphysema, I mean, its has allways been near normal. Maybe its better with a routine CT scan when you have emphysema?, and a Pft is better with bronchitis and astma ?. But!, here in Denmark you dont get a a CT scan, unless your FEV1 is degrading.
Just some thoughts.
Hope you are all doing well.
