I am a sixteen year old girl. I'm about 5' (60") tall. I'm relatively active, I play a sport on my high school team and get somewhat regular exercise otherwise. I get tired, but I rarely have real problems with my asthma; if I stay hydrated, I don't have any problems at all. However, whenever I use a peak flow meter, I can't get anything over 350 - and that's on a REALLY good day. Generally, I get between 230 and 270.

I handle my asthma using Accolate, and it's been just fine since I started. I became concerned with my peak flow readings when I found this: [url="http://www.shs.unc.edu/medservices/specialty_services/asthma/pflow.html"]http://www.shs.unc.edu/medservices/specialty_services/asthma/pflow.html[/url] which says that my breathing is worse than a 70-year-old's should be!

How should I look at this? I feel fine, I'm not having trouble, but I'm concerned that there's something I'm not seeing. Is it possible to be healthy and have peak flow readings as low as mine are?
