asthma action plan is a written plan of what to do if

The yellow zone may mean that you are having an asthma attack or that your

personal best, multiply your personal best measurement by 0.80. For example, if
your personal best flow is 400, then 80% of that is 400 times 0.80, which is
320. And 50% of your personal best would be 400 times 0.50, which is 200. In this example, the yellow zone would be any value from 200 to 320. You
may not have any symptoms, but your lung function is reduced. When symptoms are
present, they may be mild to moderate, or they may keep you from your usual

measurement, follow the
red zone instructions of your asthma action plan, because your lungs are not
responding to medicine.
If you keep going into the yellow zone from the
green zone, talk with your doctor. Your
regular medicine may need to be changed.
