This results from breathing compressed air for excessive depth and time while diving and causes excessive bubble formation in tissue and circulation causing acute occlusive and delayed inflammatory response.

• A. Barotrauma
• B. Decompression sickness
• C. Dysbarism
• D. Oxygen toxicity

Answer: (B)

Decompression sickness occurs when inert gas (nitrogen) that has dissolved in body tissues under pressure during a dive comes out of solution as bubbles during ascent. These bubbles form in tissues and the circulation, causing mechanical obstruction and triggering an inflammatory response, which explains the acute occlusive symptoms and possible delayed inflammatory effects described. The scenario—breathing compressed air at depth for excessive time and depth with rapid ascent—fits this mechanism exactly. Barotrauma is injury from pressure changes to gas-filled spaces (like ears or lungs) rather than bubbles in tissues. Dysbarism is the broader term for pressure-related disorders, not a specific mechanism. Oxygen toxicity results from high oxygen levels causing neural or pulmonary toxicity, not bubble formation. So the situation described aligns with decompression sickness.
