Body Plethysmography: Procedure, Purpose, and Uses

The idea behind body plethysmography is to measure lung volume non-invasively and outside the thorax. For this, thoracic movements during breathing are recorded as pressure changes in the surrounding air, which are converted subsequently into changes in the lung volume. This type of measurement only works in a closed set-up. One reason to perform body plethysmography could be to differentiate between restriction and emphysema, that is, chronic lung hyperinflation.
