Hey there :)
I don't know about if it happens in
100% of cases but when I'm havin
g a bad attack, my peak flow drops dramatically. When I'm weel, the best I do is about 470 but durin
attack, it can
about 150 if really bad. My asthma care is based on my peak flow readin
Ask your nurse about a plan
. You have different zones dependin
g on the readin
do for each zone.
If your peak flow is always better than
normal, I would ask your doc for advice.
