Treatment of the diving casualty.

In a diving emergency a number of specific conditions are possible in addition to those which would ordinarily be considered in a life-threatening situation. There are many separate factors which, underwater, can lead by some unfortunate combination of circumstances towards death usually, but not always, by drowning. The other major category of accidents are those resulting from the ascent of the diver to the surface. These must be considered as medical emergencies and the majority respond to immediate recompression. In the absence of readily available recompression facilities,various measures may ameliorate the condition pending transfer to a suitable compression chamber.
