What should divers do if they experience symptoms of oxygen toxicity?

• A. Continue diving until the symptoms dissipate
• B. Ascend immediately to a shallower depth
• C. Ignore the symptoms
• D. Switch to a different gas mixture

Answer: (B)

If divers experience symptoms of oxygen toxicity, ascending immediately to a shallower depth is the appropriate response. Oxygen toxicity occurs when a diver is exposed to high partial pressures of oxygen, which can lead to serious neurological effects, including seizures or loss of consciousness. By ascending to a shallower depth, the partial pressure of oxygen decreases, reducing the likelihood of exacerbating the symptoms and allowing the diver to recover more safely. Maintaining depth or continuing to dive would increase the risks associated with oxygen toxicity, as the effects can worsen with higher pressures. Ignoring symptoms could lead to severe consequences, including life-threatening situations. Switching to a different gas mixture might not be practical in a real-time diving scenario and wouldn't address the immediate concern of oxygen toxicity. Therefore, ascending to a shallower depth is the safest and most effective course of action to mitigate the risks involved with this condition.
