asthma action plan is based on zones defined by your symptoms or your peak flow, or both. It tells you what to do if

peak expiratory flow is 50% to 80% of your
personal best peak flow measurement. To find 80% of 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

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.
