I would really appreciate some help regarding a spirometry test result that I had done yesterday;but before that a very brief history. Ex smoker, very bad cough last month so asked for x-ray. X Ray result showed hyperinflated lungs consistent with COPD. (cough now gone) but because of x ray had the spirometry to cofirm or exclude COPD.
The nurse looked at results and decided I did not have COPD, so I should be happy. But I have concerns. Why were my lungs hyperinflated ? Could she be wrong about the test results ? Here are some figures from my test result
FEV1 108% of predicted (2.26 actual)
FVC 131% of predicted ((3.31 actual)
FEV1/FVC 90% of predicted (actual 68)
FEV1/FVC 100% of predicted after inhaler (actual 76)
Surely if I need an inhaler to bring my FEV1/FVC up to 100% of predicted then I must have an airway restriction/obstruction ? Don't get me wrong I am delighted and so very relieved to be told I have not got COPD but I question it. I would be SO pleased if anyone can help me
