WebThe flow-volume loop is a test of ventilatory function in which a graphic recording of maximal flow rates is displayed at all lung volumes during a maximal effort forced expiratory and inspiratory vital capacity maneuver. The test is easy to demonstrate, administer, and analyze. Pulmonary diseases produce characteristic flow-volume loop abnormalities. Web8 Dec 2024 · The flow-volume loop is a plot of inspiratory and expiratory flow (on the Y-axis) against volume (on the X-axis) during the performance of maximally forced …
