Cough peak expiratory flow. Cough peak expiratory flow (CPEF) measures an individual’s maximum speed of expiration during cough and represents the airflow through bronchi and is inversely proportional to the degree of airway obstruction. It is measured by connecting an electronic peak flow meter to the connector of an endotracheal tube
