[Lethal and neutral temperature of a helium-oxygen atmosphere for rabbits in the presence of elevated atmospheric pressure].
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.
