The total Lung Capacity (TLC) is the total volume of air accomodated in the lungs at the end of a forced inspiration. This includes:
(1) RV (Residual Volume); ERV (Expiratory Reserve Volume); TV (Tidal Volume); and IRV (Inspiratory Reserve Volume)
(2) RV; IC (Inspiratory Capacity); EC (Expiratory Capacity); and ERV
(3) RV; ERV; IC and EC
(4) RV; ERV; VC (Vital Capacity) and FRC (Functional Residual Capacity)
