Respiratory Changes and Consequences for Treatment of Decompression Bubbles Following Severe Decompression Accidents.

摘要

Earlier papers describe the theoretical and experimental work carried out to determine the best treatment strategy following severe decompression accidents during use of self-contained breathing apparatus such as the Canadian Underwater Minecountermeasure Apparatus (CUMA). The previous paper has described the extent to which decompression bubbles were formed in anaesthetized animals subjected to controlled primary and treatment hyperbaric procedures; the range of bubble counts was from zero to fatal. Treatment recompression apparently removed the bubbles quickly but in many cases this was not followed by an improvement in the condition of the animal and death occurred during the treatment. The experiments were designed to require minimal surgical intervention prior to the experiments to reduce the possibility that bubble numbers were influenced by surgery and indwelling catheters.
