Abstract : This report describes the effects of seven temperature-humidity control tests on five restrained immature chimpanzee subjects. The objective of the tests was to collect physiological data from large biological specimens under thermally-neutral environmental conditions. Test parameters were 80 F, 50 percent relative humidity for a duration of 20 hours per test. Physiological measurements recorded were respiration rate, heart rate, rectal temperature and skin temperature. Blood and urine collections were made for a metabolic profile study conducted in conjunction with the test series. Instrumentation procedures and general test techniques are described. Respiration rate in the young chimpanzee is more stable than heart rate. The average skin temperature of the immature chimpanzee is 3 F to 4 F lower than the rectal temperature, and varies considerably. Test results indicate that the subjects were exposed to significant environmental stress, probably attributable to food and water deprivation. (Author)
