What is the initial management step for suspected DCS in flight?

• A. Descend to ground level, 100% O2, land at nearest location for hyperbaric compression therapy; IV fluids 250 cc/hour NS/LR
• B. Continue flight and observe
• C. Administer antibiotics
• D. Wait and observe

Answer: (A)

In suspected decompression sickness during flight, the priority is to reduce the size of the nitrogen bubbles and maximize oxygen delivery to tissues. The best initial step is to descend to ground level (increase ambient pressure), give 100% oxygen to wash out inert gas and oxygenate tissues, and land as soon as possible at the nearest location with hyperbaric recompression therapy. Providing IV fluids helps maintain circulating volume and support tissue perfusion during this urgent situation. Descending lowers the bubble burden by raising ambient pressure, and 100% oxygen accelerates nitrogen elimination from tissues. Hyperbaric recompression therapy is the definitive treatment that further reduces bubble size and improves perfusion. Delaying treatment by continuing flight or simply observing would allow symptoms to progress and worsen outcomes. Antibiotics are not part of acute DCS management, and waiting or observing does not address the underlying issue.
