Title: [abstract] DECOMPRESSION OF MONKEYS (PAPIO-PAPIO) FROM DEEP HELIOX SATURATION DIVES.
Author: Gardette, B; Dumas, JC; Lemaire, C
Abstract: Thirteen dives were performed between - 600msw and - 1070m using monkeys (papio-papio) weighing between 4-10 kilos. For each dive, one monkey was seated on a restraining chair for EEG, EKG and EMG recordings another placed within a cage for behavioural observation. No decompression accidents were recorded during dives at 700 and 800 meters (CORASIN program). Two animals out of six suffered vestibular bends during deep dives 1000m (CORNELIUS program). During the first four decompressions of the CORASIN program, constant PI02 was used (0.5 - 0.8b); for other dives a constant O2 percentage was used for each depth range. The new method was applied for decompression of deep human dives (JANUS IV). The saturation decompression was calculated by a new method: the rate of the decompression exponential curve was a function of depth (for a given PIO2 and O2 percentage). The simple calculation method enables extrapolation of decompression for other animals of differing body weights. Tests were carried out on guinea-pigs, cats and men. The extrapolation is a function of the logarithm of the animals body weight as demonstrated by FLYNN and LAMBERTSEN (1971).
