WebForced vital capacity (FVC), forced expiratory volume in 1 second (FEV 1), FEV 1 /FVC ratio, and flow between 25% and 75% of the FVC (mean maximal flow [MMF] 25-75) are the most clinically helpful indices obtained from spirometry. Although spirometry demonstrates airflow limitations, it does not determine the cause (e.g., airway obstruction vs ... WebSpirometry is a method of assessing lung function by measuring the volume of air that the patient can expel from the lungs after a maximal inspiration. The indices derived from this forced exhaled maneuver have become the most accurate and reliable way of supporting a diagnosis of COPD.
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. Pulmonary diseases produce characteristic flow-volume loop … Webboth a volume-time curve and a flow-volume curve. There are several coding options. The 94010 code de-scribes spirometry and is grouped in APC 0367. The flow-volume CPT code 94375 could also be used, but it is in the same Medicare APC 0367 and thus pays the same technical fee (professional fees may be different in some regions).
