I just wondered how big of a difference should u expect on different machines. When I moved from the pediatric to the adults, there was a HUGE difference in my PFTs. My last FEV1 in Peds. was 90%, then when I moved to adults and did my PFTs less than 6 months later, my FEV1 was 70% and it has never come up (that was 2 years ago). My doc said there was a decline but not as bad as it looked cuz the machines measure different. I still have <b>NEVER</b>been on IVS and my FEV1 now is at 66%. This really worries me because I wouldn't think 2 machines could be so different. My brother is still at Peds and his FEV1 is at 72%, so I worry what it will be when he moves to adult next year. If they are so different how can they accurately decide your level of lung disease or when u need a transplant?
