WebThe FEV1/FVC ratio, also called Tiffeneau-Pinelli index, [1] is a calculated ratio used in the diagnosis of obstructive and restrictive lung disease. [2] [3] It represents the proportion of a person's vital capacity that they are able to expire in the first second of forced expiration ( FEV1) to the full, forced vital capacity ( FVC ). [4] WebThe four lung capacities are calculated as follows: Vital capacity (VC) = Inspiratory reserve volume (IRV) + Tidal volume (TV) + Expiratory reserve volume (ERV) Inspiratory capacity (IC) = Inspiratory reserve volume (IRV) + Tidal volume (TV) Functional residual capacity (FRC) = Expiratory reserve volume (ERV) + Residual volume (RV)
