The Piko 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. The Piko measures PEF. This is the peak expiratory flow rate. In addition, the Piko also measures FEV1. This is the Forced Expiratory Volume in the first second you exhale. Many peak flow meters measure PEF, but not FEV1. The Piko peak flow meter measures both.
