Am struggling to fully understand my results. FEV1 4.31, Fvc 5.87 and fev1fvc ratio =4.31/5.87 = 74%. As 49 year old male 188cm tall am I COPD affected or not. No real symptoms but I have been asked to do another spirometer test in 3 months following my work medical. Wish I had asked more questions at the time , am symptom free it seems and relatively fit but also ex smoker for 12 years , re what was suspected or what my results meant.
Fvc1 fvc ratio below 70% seems to be the cut off that comes up a lot on the internet but have also seen sub 80% as a cut of marker for a normal reading.
Am sure others have struggled with such readings. Anyone able to shed light on this or I will just have to wait for my next test.
Many thx, Nige
