There are a few tools you can use to keep track of your asthma and know how well your treatment is working. Keeping track of your asthma lets you act quickly to stop an attack before it becomes an emergency. Your doctor and asthma educator can help you make the plans and learn the skills you need.

A daily treatment plan tells you what controller medicine to take every day and when to take it. Controller medicine is usually an inhaled corticosteroid. Taking your controller medicine every day helps reduce the swelling of your airways and prevent attacks.

Your treatment plan may also include:

• A list of your asthma triggers-the things that make your asthma worse. Avoiding triggers can help you keep your asthma under control.
• Treatment goals. Having personal goals can help motivate you to follow your plan. For example, goals might include being symptom-free at night or being able to play sports.
• An asthma diary. In the diary, you write down your peak flow, what symptoms you are having and what caused them, and any medicines you used. See a sample asthma diary.

An asthma action plan can help you make quick decisions about treatment when your asthma is worse and you need to prevent an attack. It tells you:

• How to know when your asthma is not in control and how to change your treatment so you can prevent an attack.
• What to do if an attack becomes an emergency, and where to get medical treatment.

You and your doctor will work together to create your asthma action plan. An action plan has zones that are based on your peak flow or symptoms. See a sample asthma action plan.

Your doctor can teach you the skills you need to use your asthma treatment and action plans. These include:

• How to use a peak flow meter to check your peak flow (also called peak expiratory flow or PEF). Peak flow is a measure of how open your airways are. A drop in peak flow can show that the airways have narrowed even before you have symptoms. Then you can start treatment right away to help prevent an attack.
• How to use a metered-dose inhaler or dry powder inhaler. Using a metered-dose inhaler with a spacer is an easy way to get the medicine to your lungs. But you have to use the inhaler correctly for it to work well. If you are not sure that you are using your inhaler the right way, ask your doctor to show you how. Your doctor can also tell you if you need to use a spacer with your type of inhaler.
• What symptoms to watch for. Symptoms such as wheezing, coughing, or tiring quickly during exercise can mean that your asthma is not well-controlled. Having these symptoms may mean that you need to see your doctor and adjust your treatment.
• How to identify, avoid, and reduce triggers.

If you have ever felt that asthma controls your life, the benefits of taking an active role in your treatment can be great.

• It can help you have fewer and less severe attacks.
• It controls the inflammation in your lungs so that you have fewer asthma symptoms.
• It puts you in control so you are not limited by your disease.

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.
