What should divers do if they experience sudden symptoms after surfacing?

Seeking immediate medical assistance is crucial if divers experience sudden symptoms after surfacing because these symptoms could indicate a serious condition, such as decompression sickness (also known as "the bends") or arterial gas embolism. Both conditions can arise from rapid ascents or inadequate decompression and may worsen if not treated promptly.

When divers surface, their bodies undergo significant changes due to the decrease in pressure, which can lead to nitrogen bubbles forming in the bloodstream if decompression procedures were improperly followed. Recognizing symptoms early and obtaining medical help can prevent permanent damage and increase the likelihood of a full recovery.

Continuing to dive or waiting to see if symptoms subside can lead to severe health risks, as symptoms can escalate quickly. Utilizing a dive computer would not provide the necessary medical assessment needed in such situations, as these devices are designed for monitoring dives rather than diagnosing medical conditions. Therefore, prompt medical evaluation is the most appropriate response to ensure diver safety.
