Peak flow is how much air your child breathes out when he or she tries hardest. Your child can measure peak flow with a peak flow meter, an inexpensive device that can be used at home.
It's good to know how well your child's lungs are working. One way to do this is by checking your child's peak flow with a peak flow meter. The peak flow can tell you if your child's asthma is staying the same, getting better, or getting worse.
Checking peak flow helps your child control his or her asthma. Then asthma will not control your child.
Before you start, have your child remove any gum or food from his or her mouth.
If your child coughs or makes a mistake during the testing, do the test over.
An asthma action plan helps you and your child deal with asthma. You can work with the doctor to make an asthma action plan. The plan will include peak flow and your child's asthma symptoms.
The peak flow can help your child find out what zone he or she is in. You do this by comparing your child's current peak flow to his or her personal best peak flow. Your child's personal best is the highest peak flow recorded over a 2- to 3-week period when your child's asthma is under control.
Each meter is a little different. If you change meters, you will need to find your child's asthma zones using the new meter.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if your child is having problems. It's also a good idea to know your child's test results and keep a list of the medicines your child takes.
