What is an essential step in treating Decompression Sickness?

Administering 100% oxygen is a critical step in the treatment of Decompression Sickness (DCS). DCS occurs when a diver ascends too quickly, leading to the formation of nitrogen bubbles in the body due to a rapid drop in pressure. These bubbles can cause a range of symptoms, including joint pain, dizziness, and even more severe neurological issues.

Providing pure oxygen serves multiple purposes in this context. Firstly, it helps to eliminate nitrogen bubbles more efficiently by increasing the partial pressure of oxygen and facilitating the reabsorption of the nitrogen gas back into the bloodstream, where it can then be safely eliminated by the lungs. Additionally, the high concentration of oxygen aids in reducing inflammation and promotes healing in the affected tissues, which is crucial for recovery.

While other options such as providing pain relievers, increasing fluid intake, and applying cold compresses might offer some symptomatic relief, they do not address the underlying problem of trapped nitrogen bubbles. Therefore, while they could be part of supportive care, they lack the specific efficacy of 100% oxygen in treating DCS.
