What are the two types of gas dysbarism?

• A. None
• B. Wet Gas and Dry Gas
• C. Liquid Gas and Solid Gas
• D. Evolved Gas and Trapped Gas

Answer: (D)

Gas dysbarism from a changing pressure comes in two main forms. First, dissolved inert gas (usually nitrogen) can come out of solution as pressure falls and form bubbles in tissues and blood. This evolved gas creates bubbles that can block vessels or irritate tissues, leading to decompression sickness and related symptoms. Second, gas that is already present in closed body spaces can’t vent as pressure drops, so it expands and stretches or tears the surrounding structures—this is trapped gas barotrauma. So the two types are evolved gas, from gas coming out of solution, and trapped gas, from gas expanding in sealed spaces.
