Here's an interesting quote from the last link (the page is a person with CF who is a retired pathologist who now has a wellness/fitness coaching business):
Now, here is the part that is hard to believe. Between the antibiotics and the exercise program (nothing else changed), I seem to have grown a new lobe of lung tissue! Kidding. Not really, of course. However, I am a bit of a nerd about my pulmonary function tests. I have them dating back over 20 years. When I blew for the first time this spring after finishing the exercise program (and six weeks of antibiotics, don't forget). The volume of air I blew out in one second (FEV1) increased by 39% since the previous, and the small airway number (the FEF25-75%) improved by 70%!
I was a bit shocked by the "percent predicted" figures, having not heard those numbers in decades, so I decided it was a mistake. Maybe the norms being used were different. Maybe the machine was wrong. Then, I blew again. Same numbers. I drove home wondering how in the world scar tissue could turn into lung tissue (I'm sorry, but I still have a Pathologist sense of humor, despite retirement).
So I did what a nerd would do, and I dug out all the previous reports and compared volumes. Volumes don't lie. Sure enough, the last time I saw numbers even close to these were in my 20's. Did I mention that I'm 47?
