Relationship between airway resistance (Raw) and lung volume, the reciprocal of Raw (conductance of the airways [Gaw]) and lung volume, and Gaw/TGV (thoracic gas volume) (specific airway conductance [sGaw]) and lung volume. Relationship between airway resistance (Raw) and lung volume, the reciprocal of Raw (conductance of the airways [Gaw]) and lung volume, and Gaw/TGV (thoracic gas volume) (specific airway conductance [sGaw]) and lung volume. Notice that only sGaw is independent of lung volume. RV = residual volume. FRC = functional residual capacity. TLC = total lung capacity.
