Which term is associated with the diving-related condition known as 'The Bends'?

• A. Nitrogen Narcosis
• B. Decompression Sickness
• C. Pyelonephritis
• D. Mittelschmerz

Answer: (B)

Decompression sickness happens when a diver ascends too quickly and inert gas, mainly nitrogen, comes out of solution and forms bubbles in tissues and in the bloodstream. The term The Bends describes the painful joint and muscle symptoms that many divers experience as those bubbles settle in the body. This condition arises from the way gases behave under pressure: at depth the gas dissolves into tissues, and when pressure drops rapidly, the dissolved gas forms bubbles, potentially causing joint pain, skin changes, numbness, weakness, dizziness, chest symptoms, or neuro signs depending on where bubbles form. The best answer identifies decompression sickness because it specifically refers to the dive-related issue of gas bubbles after ascent. In contrast, nitrogen narcosis is the CNS effects of high nitrogen pressure during a deep dive, pyelonephritis is a kidney infection, and Mittelschmerz is ovulation pain—unrelated to diving physiology. Treatment focuses on removing the bubbles and delivering enough oxygen to tissues: give 100% oxygen and seek hyperbaric recompression as soon as possible. Prevention comes from slow, controlled ascents with proper decompression stops, using dive tables or a computer, and avoiding rapid ascent.
