If symptoms of decompression sickness worsen after initial treatment, what is the next step?

When symptoms of decompression sickness worsen after initial treatment, the appropriate response is to assess and compress for relief. This is crucial because recompression therapy can help alleviate symptoms by increasing ambient pressure, reducing the size of nitrogen bubbles in the body, and enhancing the absorption of nitrogen back into the body tissues.

Reassessment is necessary to determine the current state of the patient and to adjust treatment accordingly. Compression atmospheres can also provide symptomatic relief and prevent further complications. This approach ensures that the diver receives immediate care tailored to their evolving condition.

The continuation of the same treatment would not address the aggravation of symptoms and may lead to further complications. Conversely, immediate transport to the surface could expose the diver to additional risks, including the potential for further decompression sickness as they ascend. Consulting outside medical help isn't the immediate priority when internal intervention through compression therapy can be applied effectively.
