SUMMARY 1. Ventilation (V̇e) in unanaesthetized hypothermic animals remains tightly coupled to oxygen consumption (V̇o 2 ) such that V̇e/V̇o 2 remains constant despite changes in body temperature. 2. Ventilatory responses to hypoxia would suggest that, relative to metabolic rate, the gain of the respiratory system is unaltered in hypothermic animals. 3. Future studies should exercise care to ensure that the method applied in inducing hypothermia does not complicate ventilatory control and that the ability of the species to hibernate is taken into consideration.
