Bek has been doing pft's for a little over a year now and still has trouble with them at times. I was just talking to my mom about her inability to achieve a good pft on July 3rd. I believe it ranged from .76 - .82 and at the time, she still had MRSA in her lungs. They were trying to attribute her low numbers to her age. However, when we went back on the 21st, she got a 1.08 and we got the results from her sputum culture on Thursday. No more MRSA! Doc also said he didn't hear anything in her lungs this last time.
I don't think her inability to achieve a higher number was due to her age. I think it was due to what was in her lungs. We are the only one's who know our body the best, and I think she just didn't know how to express that she wasn't able to do them as well as she had in the past. Does that make sense to anyone else? She might only be 5, but she's a smart girl and knows what's going on.
