Which of the following is not a common medical gas?

• A. Nitrous Oxide
• B. Helium
• C. Hydrogen
• D. Oxygen

Answer: (C)

Hydrogen is not considered a common medical gas used in clinical settings. While hydrogen does have potential applications in specific medical research and practices, it is not widely utilized or recognized as a standard medical gas like oxygen, nitrous oxide, and helium. Oxygen is crucial for patient respiratory support and is the most commonly used medical gas. Nitrous oxide is well-known for its use as an anesthetic agent, providing sedation and analgesia during medical procedures. Helium is sometimes used in combination with oxygen for patients with certain respiratory conditions due to its unique properties that can aid in breathing. In contrast, hydrogen lacks the established medical usage and safety protocols required for the storage and administration seen with the other gases listed, which are critical to patient care and have well-defined roles in medical treatments.
