Decompression sickness is an evolved gas disorder.

Decompression sickness is an evolved gas disorder.

• A. True
• B. False
• C. Only occurs in divers
• D. Not related to gas

Answer: (A)

Decompression sickness occurs when dissolved inert gas, mainly nitrogen, comes out of solution and forms bubbles in tissues and blood as ambient pressure decreases during ascent or rapid decompression. This formation of bubbles is why it’s described as an evolved gas disorder—the gas evolves from a dissolved state into a buoyant, bubble form that disrupts tissues and the vascular system. While divers are a common scenario, decompression sickness can happen in any situation involving rapid decompression—such as high-altitude flight, astronautics, or other abrupt pressure changes. The key point is the gas coming out of solution and creating bubbles, not the setting alone. Therefore, the statement is true. The other options don’t fit because decompression sickness is fundamentally related to gas evolution, and it is not exclusive to divers.
