In-water recompression
Recompression and hyperbaric oxygen administered in a recompression chamber is recognised as the definitive treatment for DCI, but when there is no readily available access to a suitable hyperbaric chamber, and if symptoms are significant or progressing, in-water recompression (IWR) with oxygen is a medically recognised option where a group of divers including the symptomatic diver already have relevant training and equipment that provides a sufficient understanding of the associated risks and allows the involved parties to collectively accept responsibility for a decision to proceed with IWR.In-water recompression (IWR) or underwater oxygen treatment is the emergency treatment of decompression sickness by returning the diver underwater to help the gas bubbles in the tissues, which are causing the symptoms, to resolve. It is a procedure that exposes the diver to significant risk which should be compared with the risk associated with the other available options. Some authorities recommend that it is only to be used when the time to travel to the nearest recompression chamber is too long to save the victims life, others take a more pragmatic approach, and accept that in some circumstances IWR is the best available option.
