Functional residual capacity = mouth reserve + residual gas volume
Deep inhalation = inspiratory reserve + tidal volume
Total lung capacity = rated reserve capacity + tidal volume + mouth reserve + residual gas volume
Lung capacity = inspiratory reserve + tidal volume + mouth reserve
Closing capacity = closed volume + residual gas volume
Closed volume lung capacity ratio = 100 * closed volume / vital capacity
Closed volume lung capacity = 100 * closed volume / total lung volume
Residual total lung volume ratio = 100 × residual gas / total lung volume
