Hi guys I had some question about my sons Fev1 numbers. He had a clinic appointment today that went well. The only thing he said that my sons Fev1 (I think that is it) has been dropping since last March. It has gone from 110 down to 80 now. He said his pft. line is right on top of the normal line. I asked if there was anything we can do to make the number go back up and he said his breathing treatments. He does these religiously. I was surprised and exhausted since we had left for the hospital at 9 am for another appt. and didn't get home to 4:30 in the afternoon and didn't think of questions about this until I got home. So I was wondering what exactly does this mean? What if his number drops at the next visit? Does this just mean he is in the abnormal range and not a big deal? He has not cultured anything in the past except staph and h fluenza. He is not coughing any more than usual either. If anyone has any ideas, please let me know. Thanks, Janelle
