Standardisation of the measurement of lung volumes

WebFeb 27, 2024 · Body plethysmography yields a higher FRC in patients with obstructive lung disease than those measured by gas dilution techniques because it includes both well-ventilated and poorly ventilated areas of the lung. RV is generally the first volume to increase in obstructive lung disease and can be a good measure to evaluate early disease states. Webbody plethysmography’s infancy, thoracic gas volume at functional residual capacity (FRC) was the primary mea-sure recorded. Separate measures of inspiratory capacity (IC), expiratory reserve volume (ERV), and vital capacity (VC) via spirometry were used to calculate total lung ca-pacity (TLC) and residual volume (RV).1 WebMar 17, 2024 · Water Pump – The Heart of the Plumbing System.
