I really have a hard time wrapping my head around this. According to your posts, part of why he was dx'ed was due to his pft's and what his chest x-ray looked like: this indicates lung involvement. No lung involvement would indicate a normal x-ray and pft's a lot closer to 100%. There is just no getting around the physical evidence here that he does have lung involvement.
The CFF's goal for pediatric pft's is 98%. Several CF centers around the country have averages approaching or even slightly over 100%. To not be addressing lung involvement is, IMO, irresponsible and complacent on the part of a dr recommending this kind of tx. It is NOT THE STANDARD OF CARE in cf to ignore preventative care regardless of what pft's may be. It's always the goal to get them as high as possible and then keep them that way.
eta> as Sandra's post reminds me, I don't mean that I haven't heard of individual drs/centers having such a laid back or reactive approach, but it's not what the majority of drs that are experts in treating CF *and have the healthiest CF patients to show for it* recommend.
Yeah, a couple articles out there have indicated caffeine has a mild bronchodilating effect; you may have come across them online and you may find they help your son. But they are NOT a substitute for real care. And getting your son dependent on caffeine as a young teenager just seems like a bad idea all the way around.
Preventative care is the backbone of treating CF... you want to keep damage from occurring, not only be in 'damage control' mode during times of infection. You want to keep the lungs in optimal condition to avoid infection. Argh... I am getting worked up about this and should probably stop. I have seen my daughter (who has a much higher fev1 BTW), and too many other kids here, go through too much, to be able to read about a doctor make such irresponsible recommendations and remain calm about it.
I figured I'd add that Emily had pft's consistently in the low 90's after being dx'ed and just using a bronchodilator and daily vest. Upon further optimizing her therapy, it's gone up to WELL OVER 100%. What would I choose- a 'healthy' low 90's, or a 'healthy' over 100%? When the dr explains to me that the average person with cf loses a couple percentage points every year as they get older, it's a no-brainer- those percentage points gained now will eventually translate to years of life gained later.
I will also add that even with her great pft's, that when she gets sick, she really gets sick- and she has damage on her chest xray that wasn't there a couple years ago. So preventative care is absolutely, positively essential for her. I don't like to think about what we could be seeing otherwise! It's clear that while it's time consuming and takes over our life way more than what we want, it is worth it.
