What should divers do if they experience symptoms of decompression sickness?

When a diver experiences symptoms of decompression sickness, it is crucial to seek emergency medical assistance and provide information about the dive. Decompression sickness, often referred to as "the bends," can occur when a diver ascends too quickly, leading to nitrogen bubbles forming in the bloodstream and tissues. These bubbles can cause serious, sometimes life-threatening conditions, and timely treatment is vital for effective recovery.

By informing medical professionals about the details of the dive—such as depth, duration, and ascent profile—divers ensure that healthcare providers can deliver appropriate care, which usually involves hyperbaric oxygen therapy. This therapy helps reduce the size of nitrogen bubbles and aids in the reabsorption of nitrogen into the body.

Ignoring symptoms can lead to worsening conditions, while continuing to dive or attempting self-treatment could exacerbate the situation and delay necessary medical intervention. Thus, seeking prompt and professional medical assistance is the correct and most responsible course of action for a diver experiencing symptoms of decompression sickness.
