Using a Peak Flow Meter

A peak flow meter measures how fast you can push air out of your lungs. This tells you how well you are controlling your asthma. Measure your peak flow as many times a day as your health care provider tells you to.
Your Asthma Zone Action Plan (Adult)
- VHL HealthSheet #82473_VA
Peak flow monitoring lets you know how well you’re controlling your asthma. It does this by telling you which asthma zone you’re in. If needed, you’ll be given an action plan that tells you what to do if your asthma gets out of control. Your healthcare team will explain how your symptoms or peak flow numbers can help you know which zone you’re in. This chart helps you understand each zone.
