Abstract:

In a series of simulated dives--called Access-compressions were made to 800 and 1000 feet of sea water from sea level and also to these depths from holding depths of 500 and 600 feet of sea water. Compression rate was 100 feet per minute with one or two one-minute stops. The breathing gas was 3.5 oxygen and 13 nitrogen, balance helium, to give a bottom gas mixture of approximately 1 atmosphere of oxygen and about 4 atmosphere of nitrogen. The experimental program showed clearly that diving to 1000 feet of sea water can be accomplished efficiently and safely by means of excursions from moderate depths, and provided decompression procedures for such excursions. It was further shown that present saturation decompression practice can probably not be accelerated very much, and that a practical limit for present open-circuit breathing apparatus is being approached.
