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 like the unit available from Activ8rlives. This is a small, hand-held device used to monitor a person’s ability to breathe out air. It measures the airflow through the bronchi of the lungs and thus the degree of obstruction in the airways.

Peak flow readings are higher when we are well, and lower when the airways are constricted. From changes in recorded values, we may determine lung functionality, severity of asthma symptoms, and treatment options.

Measurement of PEFR requires some practise to correctly use a meter and the normal expected value depends on a patient’s gender, age and height. It is classically reduced in obstructive lung disorders, such as Asthma, COPD or Cystic Fibrosis.
