Lung volumes and lung capacities refer to the volume of air associated with different phases of the respiratory cycle. Lung volumes are directly measured. Lung capacities are inferred from lung volumes.
Total Lung Capacity (TLC): The residual volume (air you cannot expire) + vital capacity (total volume available for use) = total lung capacity. In other words, TLC is the total volume of the lungs! Minimal Volume (MV): Should the volume of the lungs fall below this value, the lungs will collapse.
