If a diver is suspected of having decompression illness (DCI) after a dive, what should you do?

Providing emergency care as you normally would is the correct approach when a diver is suspected of having decompression illness (DCI). The immediate priority in such situations is to ensure the diver's safety and address their condition without delay. DCI can potentially lead to serious complications if not treated quickly, and timely intervention is crucial in mitigating its effects.

It is essential to administer first aid and monitor the diver for worsening symptoms while preparing for the possibility of further medical assistance, such as getting them to a hyperbaric chamber. This immediate response can include ensuring the diver is in a safe environment, administering oxygen if available, and being ready to provide additional emergency care as needed.

The other approaches, such as delaying help for trained professionals or keeping the diver underwater, do not prioritize the diver's safety and could exacerbate their condition. Providing assistance only if symptoms worsen would also be counterproductive, as it might miss the critical window for effective treatment of DCI. Swift action is vital in potentially life-threatening situations such as suspected DCI.
