Your Child's Asthma: Peak Flow Monitoring

Asthma symptoms can be monitored by closely watching for early changes or by using a peak flow meter. A peak flow meter is a tool for testing how well your child's lungs are working. It can help warn you of a flare-up, even before there are symptoms. Make sure you know when you and your child should check his or her peak flow. And make sure that you and your child know how to use the meter correctly.
