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 (link opens in new window) 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.
If you or your child has been recently diagnosed, it may seem like there is a lot to remember. But the things you need to do to take charge of your asthma are really quite simple. With some practice, they will become part of your normal routine.
Each time you measure your peak flow, check your action plan to see what zone you are in. If your peak flow drops below 80% of your personal best measurement (link opens in new window) , follow your action plan. To figure out what 80% of your personal best measurement is, multiply your personal best measurement by 0.80. For example, if your personal best peak flow 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 0.50.
