You asthma action plan could save you time and money
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, 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.
Green means Go. You are in the green zone if your peak flow is 80% to 100% of your personal best measurement. This is where you want to be. Keep taking your daily asthma medicines as prescribed.
Yellow means Caution. You are in the yellow zone if your peak flow is 50% to less than 80% of your personal best measurement. You may not have any symptoms, but your lung function is reduced. When symptoms are present, you may cough, wheeze, or feel short of breath, or your asthma may limit your activities or wake you up at night.
You should take action. Your action plan will tell you what medicines you need to take, how much to take, and when to take them. If you keep going into the yellow zone from the green zone, talk with your doctor. You may need a different medicine or the dose of your medicine may need to be increased.
Red means STOP. You are in the red zone if your peak flow is less than 50% of your personal best measurement. You may be very short of breath, or the quick-relief medicines may not have worked. This is dangerous.
Take the actions listed in your action plan. You may need to go to the emergency room or be admitted to the hospital.
