What does a peak flow meter do?

ANSWER

Both children and adults can use a peak flow meter. If you have asthma, the meter can help you:

  • Track how well your asthma is under control
  • Judge how much your treatment helps
  • Spot a flare-up before it happens so you can act to avoid it
  • Help you decide if you need to call your doctor or go to the emergency room
