WebRationale: Analysis of maximal expiratory flow–volume curves (MEFVCs) allows for determination of airway obstruction, but quantitative methods to describe these curves are not commonly used. Objectives: We sought to determine the variability in MEFVC concavity assessment by pulmonary physicians, whether objective indices of concavity can be … WebConfex
WebNov 11, 2024 · The shape of the flow-volume loop can indicate the location of airflow limitation. In common obstructive airflow disorders e.g. asthma and emphysema, early evidence of airflow obstruction is qualitatively demonstrated by a concave “scooped-out” shape of the expiratory flow-volume curve. Typical flow-volume plots observed with … WebNov 3, 2024 · Flow Volume Loops. provide a graphical analysis of inspiratory and expiratory flow from various inspired lung volumes.
