Abstract : The colonic temperature of two groups of rats identified as to source were measured during repeated exposure to oxygen at high pressure (OHP) and compared with animals exposed to air at high pressure or air at barometric pressure. When exposed to OHD 60 PSIG for 30 minute exposures, the temperature decreases rather sharply (0.04C/min.) but tends to approach a limit before the decompression starts. After a period during which it is constant, it begins to rise again during the decompression but has not reached the initial value in an hour. There is a poor correlation between the occurrence of convulsions and temperature. One group of animals showed some adaptation with respect to temperature after several exposures. (Author)
