Two simulated saturation dives were conducted to monitor the physiological and biochemical responses of a model animal system to long-term diving in compressed air. The dives were performed at 50 and 60 feet of sea water for 60 and 36 days, respectively. Mean chamber CO2 was 0.42 and 0.33 surface equivalent concentration for the 50- and 60-foot dives, respectively. Mean chamber O2 was .51 ata and .58 ata for the 50- and 60-foot dives. No significant animal mortality was noted in either dive during which time over 825 male albino rats were exposed to pressure. The success of these two dives demonstrated the efficacy of long-term animal diving as a model system for investigation of the biochemical and physiological aspects of compressed air saturation diving.
