not doing CPTs
Lori,
Regarding your question as to whether their age has anything to do with PFTs, I'd say yes, to a certain extent. Though I'm not sure to what extent. When they are really young (5 or 6) they may not be able to do as well simply because of their age. But I have found the opposite is true once they get older. My younger daughter always does better than my older one. There could be many reasons for that. One is that the older they get the better they are expected to do (meaning that their "expected" is higher). For instance if it's a 6 year old they may only be expected to blow an 89 and when they do they get 100%, but by the time they are 8 they are expected to blow a 92 and if they are still blowing an 89, their lung funtion hasn't really declined but they will no longer be blowing 100% because they were expected to blow higher. They may only get 98% but really nothing has changed except what they were expected to do. (those numbers are completely out of my head...not reality at all...I'm just using them as an example)...I don't know if that made any sense at all. It's easier to say than to write.
Another reason I think there is such a difference in my girls is because my older daughter was undiagnosed until she was 2 1/2 and was very very ill. (pneumonia, constant uncontrolable wheezing, losing weight, etc) until she was finally diagnosed. She almost died of pneumonia when the week she turned 2. She was extremely sick. But once she was diagnosed and started being treated correctly she improved dramatically and has not been hospitalized since her 3rd birthday. She will be 12 in December. My younger daughter was diagnosed before birth and so has always been treated properly and has never had a lung infection (several sinus surgeries though). I guess that does suggest that the treatments are doing something. There was once when we went for 7 days without treatments (that's by far the longest ever) and I could not tell it at all. Neither girl had any problems. But I wouldn't want to make that a habit. We were on a cruise and although we had the vest and stuff with us, the girls were so active and so busy we never slowed down enough to do them. If they had had any problems I would certainly have pushed the issue and make them do the treatments. I think other than one occasion, a weekend is the longest they have ever gone without treatments, and again, that's not a habitial thing. I'm just too scared of what MIGHT happen.
