How to take charge of your asthma

Follow your daily treatment plan

• Take your daily medicines as prescribed. This can keep asthma under control and help you avoid asthma attacks.
• Keep your treatment goals in mind. This may help you stick with your treatment.
• Review your list of triggers. Avoiding triggers can help reduce the chance that you will have an asthma attack.

Check your peak flow

• Use your peak flow meter. This is the best way to check how well your lungs are working, which is called lung function. Your lung function can get worse without causing symptoms.
• Check your peak flow as often as your doctor tells you to. For many people this is twice a day, morning and evening.
• If you have trouble using your meter, talk to your doctor.

Use your asthma action plan

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 stay in the hospital.

Use your asthma diary

• Write down your peak flow readings in the asthma diary.
• If you have an attack, write down what caused it (if you know), the symptoms, and what medicine you took.

See your doctor to review your plans

Keep your regular follow-up appointments. During checkups, your doctor will ask if your symptoms and peak flow have held steady, improved, or gotten worse and if you have asthma attacks during exercise or at night. Your doctor may want to see how you use your peak flow meter. This information can help your doctor know if your asthma category has changed or if you need to change medicines or doses.

When you go to your doctor:

• Take your daily treatment plan, your asthma action plan, and your asthma diary. Get answers to any questions you may have about your asthma plans or your symptoms. Let your doctor know if treatment is not controlling your asthma symptoms.
• Take your peak flow meter and medicines so your doctor can review your treatment and the way you use the meter and medicines.
• Make sure you know how and when to call your doctor or go to the hospital.
• Tell your doctor if you are having trouble following your action plan.
