Monitoring Your Symptoms

It is very important to check your asthma symptoms. Then you can take action if there is a change. There are 2 ways to check your symptoms. Some people use a peak flow meter. The peak flow meter measures how well air is moving in your lungs. And some people keep track of small changes in their symptoms. They write them down every day. Your healthcare provider will help you figure out which way is best for you. He or she will also tell you what to do if your symptoms get worse.

If you use a peak flow meter, you should know your personal best reading. You should also know how to use the meter correctly, and how often you should measure your peak flow.
