Which action should NOT be taken if you suspect a diver is experiencing decompression sickness?

When a diver is suspected of experiencing decompression sickness, it is crucial to act promptly and effectively to ensure their safety and recovery. The option that should NOT be taken is the delay in seeking medical assistance. This is critical because decompression sickness can worsen quickly if proper treatment is not initiated, making immediate medical intervention essential.

Administering pure oxygen, if available, can help alleviate symptoms, as oxygen helps reduce the size of nitrogen bubbles and improves tissue oxygenation. Moving the diver to a warm environment may help counteract hypothermia, which can exacerbate the situation, and continuous monitoring of their symptoms allows for an informed and timely response to any changes in their condition. Each of these actions is aligned with the best practices for dealing with decompression sickness, underscoring the importance of not postponing medical help.
