What Does PEF Stand For?

PEF stands for Peak Expiratory Flow

PEF, or Peak Expiratory Flow, is a measurement used to assess pulmonary function by determining the maximum speed of expiration. It is commonly utilized in the monitoring of respiratory conditions, such as asthma, to evaluate airway obstruction and guide treatment decisions. PEF is measured using a peak flow meter, providing valuable data for patients and healthcare providers to manage respiratory health effectively.
