S I did this spiro in france but didn’t really understand it well when I was doing the test ….. I did a handheld spiro back in the uk couple months later and my results of my fvc was 4.62 93% and my fev1 was 4.10 which was 97% ….. but I got told chronic bronchitis after a respiratory Ct scan which I think was based on my symptoms but no one said copd can anyone help me translate my first spiro as that was done in some tiny isolated tube/box ….
