What is the primary concern when handling a diver who may have decompression sickness?

The primary concern when handling a diver who may have decompression sickness is to keep them calm and still. Sudden movements or excessive activity can exacerbate the symptoms and potentially lead to further complications. By maintaining a calm environment and ensuring that the diver remains still, the risk of air bubbles expanding in the body, which can occur with movement, is minimized. This is particularly important as the diver's body is likely already under stress from the possibility of nitrogen bubbles forming in the bloodstream or tissues.

Maintaining composure helps reduce panic, which can increase heart rate and blood pressure, potentially worsening the situation. It's essential for the diver to conserve energy and allow medical professionals to address the issue effectively rather than complicating the situation with movement-related stress.

While monitoring vital signs and getting the diver to a hospital are also important aspects of care, the immediate priority focuses on calming the diver and preventing further injury from unnecessary movement. This foundational approach can significantly influence the outcome of the incident.
