Asthma
Peak Flow Meter
A peak flow meter for asthma is like a thermometer for a fever - it helps you monitor what's going on inside your lungs by measuring airflow out of the lungs. The meter can tell you if your airways are narrowing well before asthma symptoms begin. Learn how to use a peak flow meter, how to find your "personal best," and how to set your peak flow zones.
