Abstract

The 5 to 20-day stay of the rabbits in helio-oxygen medium at the pressure of 3534 kPa revealed a linear interrelationship between the temperature 297-302 K and oxygen consumption. At the low lethal temperature of 294 K rabbits perished within 24 hrs due to growing hypothermia. At the neutral temperature 302 K the respiratory heat loss constitutes 30-38% of the basal metabolism, heat loss from the skin surface decreases. The hyperbaric medium seems to have no thermoneutral zone adequate to air by its physiological effect.

摘要

兔子在3534千帕压力的氦氧介质中停留5至20天,结果显示温度在297 - 302K之间与氧气消耗呈线性相互关系。在294K的低致死温度下,兔子因体温过低在24小时内死亡。在302K的中性温度下,呼吸散热占基础代谢的30 - 38%,皮肤表面的散热减少。高压介质在生理效应方面似乎没有与空气相当的热中性区。
