An Asthma Action Plan is your guide to dealing with your daily asthma symptoms and how to respond to asthma emergencies. Your health care team will help you develop your plan.

An asthma journal can help you keep track of your good and bad days, your triggers, and your symptoms. You and your health care professional can use this information to optimize your asthma treatment plan.

If you use a peak flow meter, a peak flow diary can help you to keep track of your peak flow records.

You will take your asthma medicine with one or another of several common devices. An inhaler is the most common device used to deliver asthma medicine. It is vital that you learn how to use an inhaler properly so that you, or someone you are caring for, can get the most out of the asthma medicine your doctor prescribes.

A peak flow meter measures how well air is moving out of your lungs. Finding changes in lung function leads to early treatment and better control of asthma. Nebulizers turn asthma medicine into a fine mist, which you breathe in with a mask or a tube. They are made for those who are too young or too ill to use an inhaler.

A spirometry test is used to diagnose asthma or to assess the severity of someone's asthma. It measures your lungs' ability to expel air.
