[Effect of increased pressure of nitrogen on thermoregulation of mammals].
Consumption of oxygen in rats was studied under conditions of the gas different ambient temperatures and pressure. A dependence was revealed between the neutral temperature and the high gas pressure. Mathematical model revealed an increase oxygen consumption at an increase gas pressure. The data suggest that the animal body temperature may be kept unaltered through an increased pressure of oxygen-nitrogen as a compensation of the heat transmission increased in an increased oxygen consumption.
