Peak Expiratory Flow Definition

Peak Expiratory Flow (PEF) - one of the lung function testing parameters measuring the rate at which a patient can exhale for vital lung capacity evaluation. PEF records the maximum flow that can be sustained for 10 milliseconds on forced expiration starting from full inflation of the lungs. It is a useful tool in defining characteristics and monitoring such conditions as obstructive lung disease, asthma, and bronchitis.
