Q. In hospitals, the oxygen tubes for respiration contain oxygen and

1. nitrogen
2. helium
3. argon
4. carbon dioxide

Answer: Helium

Helium oxygen mixtures in the oxygen tube of an intensive care unit.

Heliox, a mixture of helium and oxygen, has a density that is less than that of air. Breathing heliox leads to a reduction in resistance to flow within the airways, and consequently to a decrease in the work of breathing (WOB), particularly in disorders that are characterized by increased airways resistance.

In hospitals, the oxygen tubes for respiration contain oxygen and helium. This mixture of Oxygen and Helium is called Heliox.

Heliox is a breathing gas composed of a mixture of helium (He) and oxygen (O₂). Heliox is a medical treatment for patients with difficulty breathing.
