What should a diver do if they suspect decompression sickness (DCS)?

If a diver suspects decompression sickness (DCS), the most critical action is to seek emergency assistance. Decompression sickness can occur when a diver ascends too quickly or fails to follow proper ascent procedures, leading to bubbles forming in body tissues or the bloodstream. These bubbles can cause serious and sometimes life-threatening complications.

Prompt medical evaluation and treatment are essential because DCS can deteriorate rapidly. The most effective treatment for DCS is recompression therapy in a hyperbaric chamber, which helps to reduce the volume of nitrogen bubbles, restore normal physiological function, and alleviate symptoms.

While other options may seem tempting, they do not effectively address the potential seriousness of DCS. Continuing to dive or testing symptoms can worsen the condition, and resting or taking deep breaths may provide temporary relief but do not address the underlying problem. Therefore, immediate access to medical care is vital for any suspected case of DCS.
