What is the first aid treatment for decompression illness?

Administering oxygen is the appropriate first aid treatment for decompression illness because it helps alleviate symptoms and reduce the severity of the condition. Decompression illness, which can occur due to the formation of nitrogen bubbles in the body following rapid ascent from deep dives, can lead to significant tissue damage. Providing supplemental oxygen increases the partial pressure of oxygen in the bloodstream, facilitating the elimination of nitrogen bubbles and decreasing hypoxia. This treatment can also help reduce gas embolisms and improve overall patient oxygenation, making it a critical step in the immediate management of decompression illness.

While hydration therapy, resting, and monitoring are important components of overall care, they are not immediate interventions aimed at addressing the root issue of decompression sickness. Administering pain relief medication may help manage discomfort but does not address the underlying problem. Therefore, the provision of oxygen is vital for treating this serious condition effectively.
