Editing In-water recompression (section)

== "Informal" in-water recompression ==
Although in-water recompression is widely regarded as risky, and to be avoided, there is increasing evidence that technical divers who surface and demonstrate mild DCS symptoms may often get back into the water and breathe pure oxygen at a depth of {{convert|20|ft|m|abbr=off|sp=us}} for a period in an effort to alleviate the symptoms.  [[Divers Alert Network]]'s 2008 accident report mentions this trend, and that although the reported incidents showed very little success, "[w]e must recognize that these calls were mostly because the attempted IWR failed. In case the IWR were successful, [the] diver would not have called to report the event. Thus we do not know how often IWR may have been used successfully."<ref name="DAN 2008" />

Historically, the pearl divers of Broome, Western Australia, used decompression tables developed from personal experience, and would return to depth if symptoms of DCI developed on surfacing. These dives and recompression were done on air, using [[standard diving dress]], which provides relatively good airway security. Success was variable, but some divers were treated in this way on several occasions.<ref name="Bailey 2002" />
