Helium of lungs
Web11 nov. 2024 · During a helium dilution test, you would breathe from a container containing a known fraction of helium gas. A spirometer measures the change in the concentration of the gases in the container. This test is conducted in a closed system circuit. It is used less frequently than body plethysmography. 3 Body Plethysmography Web23 nov. 2016 · Lung volumes including residual volume (RV) and total lung capacity (TLC) were determined by both body plethysmography and helium dilution methods.
