Peak Flow Meters
An oral peak flow meter measures how well air moves out of your lungs. You can use a peak flow meters to check your asthma the way that blood pressure cuffs are used to check high blood pressure. By taking your medicine(s) early (before symptoms), you may be able to avoid a severe asthma episode.
The peak flow meter also can be used to help you and your doctor:
- Learn what makes your asthma worse
- Decide if your treatment plan is working well
- Decide when to add or stop medicine
- Decide when to seek emergency care
A peak flow meter is most helpful for people who must take asthma medicine daily. Children as young as age 5 are usually able to use a peak flow meter. Ask your health care provider to show you how to use a peak flow meter.
