Non-invasive Screening of Expiratory Flow Limitation in Chronic Obstructive Pulmonary Disease
Peter Calverley, Raffaele L Dellacà
Take home messages A hallmark of chronic obstructive pulmonary disease (COPD) is the occurrence of expiratory flow limitation (EFL) during a forced expiratory manoeuvre at lower expiratory flows compared with healthy subjects. Forced oscillation technique provides an objective, non-invasive measure of tidal EFL that does not require the performance of respiratory manoeuvres and offers a […]
