Background: Human lung capacity can be measured in several ways. Summing specific lung volumes produces the following lung capacities: The total lung capacity (TLC), about 6,000 mL, is the maximum amount of air that can fill the lungs (TLC = TV + IRV + ERV + RV). Inspiratory Capacity = Tidal Volume + Inspiratory Reserve 2. 0000001291 00000 n 0000071785 00000 n As you can see from figure 1, there are a number of different lung volumes and capacities that are useful to measure, but we're going to focus tidal volume (TV), vital capacity (VC), and the forced expiratory volume in one second (FEV 1).. Lung Volumes and Capacities Tidal Volume (TV) : The amount of gas inspired or expired with each breath Inspiratory Reserve Volume (IRV) : The maximum amount of additional air that can be inspired beyond a normal inspiration What percentage of oxygen is exhaled during normal exhalation by a human?
