asthma action plan is a written plan of what to do if
you have an
asthma attack. You are in the red zone of your asthma
action plan if you have severe asthma symptoms. Symptoms include:
Peak expiratory flow less than 50% of

your personal best measurement by 0.50. For example, if your personal best flow
is 400, then 50% of that is 400 times 0.50, which is 200. In this example, a peak expiratory flow less than 200 means you are in the red zone.
shortness of breath while walking, talking, or at rest.
Use of the
chest muscles to breathe. The skin between, above, and under the ribs collapses
inward with each breath (retractions).
