How to use a peck flow meter: Dr Steve Rubinstein, an allergist, demonstrates how to use a peak flow meter. People with asthma should know what their best peak flow is when they feel well. Then when you are feeling short of breath, you can tell based on your peak flow, how much your asthma is contributing to the shortness of breath. Peak flow can also help to determine if a cough is due to asthma.
