Children's Asthma Peak Flow Calculator

This calculator is for children with asthma. If you know how tall your child is, you can find out what their estimated personal best peak flow value should be. Peak flow is how fast your child breathes out air after taking a deep breath. Your child's peak flow tells you and your child's healthcare provider how well your child's lungs are working.

You need to know your child's personal best peak flow number to help control your child's asthma. This number is part of your child’s Asthma Action Plan.

Changes from your child's personal best can help you see how well your child's asthma is under control. These changes also can let you know when your child needs medicine and when your child needs medical care.

If you don't know how to find your child's personal best peak flow, click here for an explanation.

Note: The calculator will only work if your child is between 43 inches and 65 inches tall.
