Answer: B-Heliox should be administered to a patient who has an obstruction in the large airways and is not getting adequate oxygenation.

Heliox is a mixture of helium and oxygen. It is therapeutic in areas of turbulent flow. The density of heliox is less than that of oxygen and is beneficial to patients with large airway obstructions but does not affect the small airways where the flow is laminar. The recommended mixture is 80% helium with 20% oxygen.
