Asthma symptoms can be monitored by closely watching for early changes or 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 their peak flow. And make sure that you and your child know how to use the meter correctly.
A peak flow meter measures how fast you can push air out of your lungs. Your peak flow reading may be an early sign that your asthma is getting out of control. Read on to learn the steps for using a peak flow meter.
