Recompression prevents further bubble formation and provides high amounts of oxygen to the injured tissues. When the bottle is opened, the pressure is released and the gas leaves the solution in the form of bubbles. Blood and urine will be sent for laboratory tests to assess any blood clotting problems and hydration status. Physicians usually diagnose the disease based on the result of a physical exam and blood tests. The other effective method to treat this disease is Recompression on room air. This is due to gas from the chamber dissolving into the skin and forming bubbles under the skin. In some cases, it is mild and not an immediate threat. Decompression Sickness Treatment.
