A peak flow meter is a small, easy-to-use instrument that enables you or your child to measure lung function at home, at work, at school wherever you go. The peak flow meter measures how fast a person can blow out air after a maximum inhalation. It helps reveal how well you or your child's lungs are working. This is called the peak expiratory flow rate.
