WebSome lung volumes can be measured during spirometry; however, measurement of the residual volume (RV), functional residual capacity (FRC), and total lung capacity (TLC) requires special techniques. FRC is typically measured by one of three methods. WebOct 22, 2024 · Total lung capacity (TLC) is the maximum volume of air the lungs can hold. It is measured by assessing the total amount of air in the lungs after taking the deepest breath possible. Lung plethysmography, one of several pulmonary function tests, is used to determine TLC, and this assessment of lung function can assist in diagnosing and ...
