Children's Asthma Peak Flow Calculator


Children's Asthma Peak Flow Calculator

Introduction

This calculator is for children with asthma. If you know your child's height, you can find his or her predicted peak flow meter value. Peak flow is how fast your child exhales air after taking a deep breath. Your child's peak flow tells you and your child's doctor 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. 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 medication and when your child needs medical care.

If you don't know how to find it, click here for an explanation.

Note: The minimum height for this calculator is 44 inches.
