A peak flow meter allows you to measure day-to-day changes in your breathing. Using a peak flow meter can help you:
- Track the control of your asthma over time
- Show how well your treatment is working
- Recognize signs of a flare-up before symptoms appear
- Know what steps to take when you have signs of an asthma flare-up
- Decide when to call your doctor or get emergency care
