Peak Flow Meter
This four-page illustrated handout educates people about how to use a peak flow meter, which is a device that measures air flow out of the lungs to show how well a person's asthma is under control. It provides step by step instructions for using a peak flow meter. The document explains what the readings mean, and classifies results into three color-coded peak flow zones, clarifying what specific action the patient should take with each particular reading. It contains spaces where a healthcare provider can write in target numbers for each peak flow zone.
