WebBody Plethysmography Plethysmography is derived from Greek word meaning enlargement . Body plethysmography primarily measures FRC using Boyle's law. It is particularly appropriate for patients who have air spaces within the lung that do not communicate with the bronchial tree. WebFeb 7, 2007 · In COPD, the RV increases more than the TLC, resulting in some decrease in vital capacity. Airway resistance can be measured directly using whole-body plethysmography, but is more commonly inferred from dynamic lung volumes and expiratory flow rates, which can be obtained more easily. 1.
