WebAug 22, 2005 · In COPD, destruction of elastic tissue commonly associated with emphysematous changes in the lung alters lung recoil, shifting the relationship between lung volume and distending pressure (pressure–volume curve) so that a given lung volume produces a lesser recoil pressure than in the healthy lung. WebTotal Lung Capacity (TLC) It is the maximum volume of air the lungs can accommodate or sum of all volume compartments or volume of air in lungs after maximum inspiration. The normal value is about 6,000mL (4‐6 L). TLC is calculated by summation of the four primary lung volumes (TV, IRV, ERV, RV).
