What is the main focus of treatment for Type II decompression sickness?

The primary focus of treatment for Type II decompression sickness is recompression in a chamber, which is also known as hyperbaric oxygen therapy. This treatment involves placing the affected individual in a hyperbaric chamber where they are exposed to increased atmospheric pressure and pure oxygen.

This method is effective in treating Type II decompression sickness because it helps reduce the size of nitrogen bubbles that may have formed in the tissues and bloodstream during a rapid ascent. The increased pressure allows for better absorption of oxygen in the body, which aids in healing tissues and enhances the elimination of nitrogen bubbles.

Hyperbaric therapy not only alleviates symptoms but also prevents potential long-term damage that can occur due to decompression sickness, such as neurological complications or damage to the lungs. The recompression process is critical to support the body's physiological responses to decompression illness effectively.
