Peak Flow Meter
En espaÃ±ol: Medidor de flujo mÃ¡ximo
A peak flow meter can tell you how well your lungs are working.
It's great for a person with asthma because it can tell if the
airways have narrowed, even before the person coughs,
, or has trouble breathing. To use it, a person blows into it and
then checks the reading. It's portable, it doesn't need to
be plugged in, and you don't need a doctor or nurse to use it.
Many people use a peak flow meter at home to see how well
they're keeping their asthma under control.
