How do you calculate thoracic volume?

The total lung capacity (TLC) is the volume of gas in the lung at the end of a full inspiration. It is either calculated from: TLC = RV+IVC, or from: TLC = FRC+IC; the latter is the preferred method in body plethysmography. It can also be measured directly by the radiologic technique.

small net changes in intrathoracic blood vol- ume. According to the other,3because of its flexibility the chest wall is collapsed in the amount of one-third to one-half of the stroke volume by the fall in pressure due to net ejec- tion of blood from the thorax during systole. This fall in pressure is also said3to be an im-
