Question

Which of the following is the life-saving mixture for an asthma patient?

Options

• Mixture of helium and oxygen

• Mixture of neon and oxygen

• Mixture of xenon and nitrogen

Mixture of helium and oxygen

Explanation:

Helium has a very low density, which allows the oxygen mixture to flow much more easily through narrowed airways. This significantly reduces the effort required for an asthma patient to breathe.
