Lung capacity varies widely depending on a person’s age, sex, weight and activity level. Functional residual capacity (FRC) = Expiratory reserve volume (ERV) + Residual volume (RV) Total lung capacity (TLC) = Inspiratory reserve volume (IRV) + Tidal volume (TV) + Expiratory reserve volume (ERV) + Residual volume (RV) The following table introduces the average normal values for lung capacities for men and women: Lung volumes measurement is an integral part of pulmonary function test.
