Asthma - Peak Flow Meters
Peak Flow Meters Are Important in the Management of Asthma
A peak flow meter is a device that measures how fast air is moved from the lungs. The color coded zones on a peak flow meter are similar to the signals on a traffic light representing safety, caution and danger, which is an indication of whether an individual’s asthma is under control.
A health care professional can assist in determining personal best readings. If you are not using a peak flow meter, talk to your provider.
