Question

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

• A. Mixture of helium and oxygen.
• B. Mixture of neon and oxygen.
• C. Mixture of xenon and nitrogen.
• D. Mixture of argon and oxygen.

Answer 1

The correct option is A Mixture of helium and oxygen.

Mixture of helium and oxygen (density 2) is lighter than air (density 14.4). Hence, it diffuses more rapidly through constricted lung passages.

Mixture of helium and oxygen is used as life saving mixture for an asthma patient.
