Recompression treatments should be to a pressure equivalent to 18 m depth
Bubbles decompression illness hyperbaric oxygen treatment
2009/5/18
One therapeutic goal of recompression treatment of
decompression illness (DCI) is a reduction of bubble
volume. The higher the pressure the smaller will be the
bubble volume, but high pressure is a...
