WebFeb 1, 1973 · The 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. WebSpirometry with flow-volume loops assesses the mechanical properties of the respiratory system by measuring expiratory volumes and flow rates. This test requires the patient to make a maximal inspiratory and expiratory effort. The patient, in a sitting position, breathes into a mouthpiece, and nose clips are placed to prevent air leak.
