Columbia now has a NEW PFT machine.
I went in on Tuesday and did my PFT's on the old machine and had the same numbers.
Then on the new machine, my FEV1 dropped 20 points! Now, I understand that it's relative and I've been told that all patients have had this, but it seems like a pretty big drop despite the advancement of technology.
Anyone with already low numbers have even lower numbers? I'm thinking that pre TX, I was at 20% then I must've been closer to 15%.
