In April after nasty chest infection, I had CT scan and Spirometry test and came away with diagnosis of COPD (emphysema and chronic bronchitis) was advised to ditch the cigs, which I did and that would help slow down the decline in lung function. It wasn't too bad Fev1 67%
Since then I've done the pulmonary rehabilitaion course and walked as much as I could, today was my first check up with the nurse. I didn't think you could improve lung function :/ but my Fev1 is now 75% confused but in a good way.
