helium therapy

helium therapy

the use of helium-oxygen gas mixtures to treat patients with airway obstruction. Because of its low density, helium can negotiate an obstruction more easily than nitrogen can, so less driving pressure is required to move the gas mixture in and out of the lungs.

he·li·um ther·a·py

(hē'lē-ŭm thār'ă-pē)
The use of a helium-gas mixture (usually helium and oxygen) in the management of obstruction of the airways; the density of helium is much lower than that of either air or oxygen; as a result, the gaseous mixture will move past an airway obstruction more easily.
