During an asthma attack, the airways
swell and narrow. This makes it hard to breathe. Asthma is a lifelong problem,
but it does not have to limit you. If you take charge of your asthma, you can
lead a full and active life.
You and your doctor will make an
asthma action plan that outlines the two approaches to
taking charge of asthma:
Using the asthma action plan also helps you keep track of
your asthma and know how well your treatment is working.

Check your symptoms or your peak flow, or both, on a regular basis, and use your action plan to see what
zone you are in. If you have yellow zone symptoms or if your peak flow drops below 80% of your
personal best measurement, follow your action plan. To

is 400, then 80% of that is 400 times 0.80, which is 320. To figure what 50% of
your personal best peak flow is, multiply your personal best measurement by
Keep your regular follow-up appointments. During
checkups, your doctor will ask if your symptoms or your peak flow, or both, have held steady,

during exercise or at night. This information can help your doctor know if your
asthma category has changed or if you need to change
medicines or doses.
