Had my lung function test today, I was a little worried that while i'm on pred, and so many other meds and was actually feeling pretty good (chest clear as you would expect for lungs which know they're going to see a doctor) i might not show much reversibility at all. so i was pretty reluctant and part of me wanted to not go coz I dont want my lungs to look so great on paper when i feel so rubbish. I wasn't at all surprised when the guy doing the test said my lungs seemed to be ok, only slightly below predicted (all around 80% of prediction values) but after 6 puffs of ventolin and a 20min wait my peak flow had increased by 66%, and fev1 by 27%. The result was so significant my mannitol challenge has been cancelled, as I clearly have a high degree of reactivity and reversibility in my airways. As much as I want my lungs to be etter than they are, i am just so relieved to have something that SHOWS how i feel! all my lung volumes were lower percentages of predictd, i got the impression that was a good thing in asthma as it means i am still getting rid of the air, even if its not easy! one thing that did confuse me was that my lungs dont seem very good at diffusion. 65% of predicted? that doesnt sound good! but not sure what causes that? could it be inflammation in my lungs making the diffusion pathways larger? i dont really understand this stuff! Also, the guy looked up my Hb to see if that was causing my poor diffusion (it wasnt) and he mentioned that i had a high level of 'allergicness' in my blood (ok..he might not have said allergicness but that was the implication) so hopefully this will help them understand whats going on a bit better, maybe we can actually find something thats going to make a difference now! fingers crossed! but yeah...wanted to share the good-ish news! hope everyones well!
