[edit on Wikidata] The peak expiratory flow (PEF), also called peak expiratory flow rate (PEFR) is a person's maximum speed of expiration, as measured with a peak flow meter, a small, hand-held device used to monitor a person's ability to breathe out air.
Predictive Normal Values have been calculated for women and men of different ages and heights, and have been adapted (with agreement from the original Authors) for use with the new EU Scale / EN 23747 peak flow meters.he change in scale for peak flow meters will result in PEF readings that are different, depending on whether the individual has used a Wright scale meter, or the new EU scale meter.
