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 … WebBody plethysmography is a very sensitive lung measurement used to detect lung pathology that might be missed with conventional pulmonary function tests. Spirometry is the standard method for measuring most relative lung volumes; however, it is incapable of providing information about absolute volumes of air in the lung.
