Asthma: Measuring Peak Flow

As someone with asthma, you know how important it is to monitor your condition. You need to know how well your lungs are "working." Is their ability to move air in and out staying the same, or is it getting better or worse?

When you monitor your asthma, you can control it. When you control your asthma, you also control your life—you do what you want to do, and your asthma does not limit you.

Measuring your peak expiratory flow is an important part of monitoring your asthma.
