What is the composition of medical air?

• A. 60% nitrogen, 30% oxygen, 10% trace gases
• B. 78% nitrogen, 21% oxygen, and trace gases
• C. 50% oxygen, 50% nitrogen
• D. 100% oxygen

Answer: (B)

Medical air is a specific mixture of gases that closely resembles the composition of atmospheric air. Its primary components are nitrogen and oxygen, along with trace gases that are present in small amounts. For medical air, the standard composition is approximately 78% nitrogen, 21% oxygen, and about 1% trace gases such as argon, carbon dioxide, and others. The significance of this composition lies in its similarity to what individuals naturally breathe, promoting safety when used in medical applications. Medical air is often utilized in various therapeutic and respiratory treatments, ensuring that patients receive a gas mixture that is non-toxic and conducive to normal physiological function. Understanding this composition is essential for healthcare professionals as it informs the appropriate usage of medical air in various treatment protocols, differentiating it from other medical gases that may contain higher concentrations of certain gases, such as pure oxygen.
