PEAK EXPIRATORY FLOW: MEASURING

Course overview

Peak expiratory flow (PEF) is a measurement of the maximum flow of air expelled during forced expiration, and is an indicator of airway caliber. PEF measurements are performed to assess for airway obstruction and evaluate pulmonary response to bronchodilator therapy in patients with obstructive airway diseases. This continuing education module is designed to give the reader/learner an increased understanding of PEF measurement in order to better care for patients with airway obstruction. Readers may explore any or all of the topics. One contact hour of continuing education credit is available for those who successfully complete the post-test and evaluation form.
