Peak Flow Meter
A peak flow meter is a device that measures how well air moves out of your lungs. Peak flow meters are used to check your asthma the way that blood pressure cuffs are used to check high blood pressure.
During an asthma episode, the airways of the lungs usually narrow slowly. The peak flow meter may help warn you if there is narrowing in the airways hours, and sometimes even days, before you have any asthma symptoms.
The peak flow meter also can be used to help you and your doctor:
- Learn what can make 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.
Ask your healthcare provider to show you how to use your peak flow meter. Take time now to get a better understanding of the benefits of this device:
Measure your peak flow consistently, every day. Proventil.com has a personal online Peak Flow Diary to help you track your readings.

Important Safety Information
If your symptoms become significantly worse when you use PROVENTIL® HFA or Albuterol (CFC) Inhalation Aerosols, contact your doctor immediately because this reaction can be life threatening. Worsening symptoms often occur with the first use of a new canister.
What to tell your doctor before using PROVENTIL® HFA or Albuterol (CFC) Inhalation Aerosols: If you have a heart, blood, or seizure disorder, high blood pressure, diabetes, or an overactive thyroid, be sure to tell your doctor. Also make sure your doctor knows all medications you are taking — especially heart medications and drugs that treat depression — because some medications may interfere with how well your asthma medications work.
