Following from my last post I had spirometer today and these are my results. I'm 31 female. Specialist said it's normal but will have more detailed one in a month. Can anyone shed any light do they seem normal? I'm clueless all I can see is that my predicted fev1 should be 8.3 but is 7.8 and I'm worried. have been having symptoms of shortness of breath have been taking symbicort and ventolon which helps.
