What is the first step in treating a diver suspected of decompression sickness?

Transporting a diver suspected of decompression sickness to a hyperbaric chamber is critical because this facility is equipped to deliver hyperbaric oxygen therapy, which is the primary treatment for this condition. Decompression sickness occurs when nitrogen bubbles form in the body due to rapid changes in pressure; these bubbles can cause serious harm to tissues and organs. Hyperbaric oxygen therapy helps to reduce the size of these bubbles, improve oxygen delivery to tissues, and mitigate the effects of nitrogen narcosis and other complications.

Immediate action is important in managing symptoms and preventing further injury. While other actions, such as removing diving gear or administering fluids and pain relievers, may be essential parts of the treatment process, the definitive care for decompression sickness is hyperbaric oxygen therapy, making transportation to a hyperbaric chamber the foremost priority.
