Total lung capacity (TLC) is the maximum volume of gas contained in the lungs after the maximal or forced inhalation
TLC is used to determine the normal function of the lung or the diseases state
Formula used:
TLC = ERV + IRV + RV + TV
TLC = Total lung capacity
ERV = Expiratory reserve volume
IRV = Inspiratory reserve volume
RV = Residual volume
TV = Tidal volume
