Which condition is definitively treated in a recompression chamber for diving-related emergencies?

• A. Decompression sickness
• B. Allergic reaction to chlorine
• C. Mild dehydration
• D. Ear barotrauma without symptoms

Answer: (A)

Decompression sickness is treated definitively in a recompression chamber because hyperbaric therapy directly addresses the root problem: gas bubbles in the blood and tissues that form after a diver ascends too quickly. By increasing ambient pressure, the bubbles shrink, and breathing 100% oxygen helps dissolve the inert gas (nitrogen) back into the blood more rapidly. This combination not only halts the ongoing injury but also restores oxygen delivery to affected tissues, which is why recompression with hyperbaric oxygen is the standard, definitive treatment for DCS. Other scenarios don’t involve gas bubbles causing tissue injury in the same way. An allergic reaction to chlorine is managed with allergy-focused care (airway protection, antihistamines, epinephrine). Mild dehydration is treated with fluids. Ear barotrauma without symptoms doesn’t require pressure therapy; it’s typically managed with symptom control and avoidance of further pressure changes, reserving chamber treatment for more significant barotrauma or decompression-related injuries.
