[Blood gases in craniocerebral hypothermia].

Experiments were conducted on dogs; cranio-cerebral hypothermia (a reduction of body temperature from 38 to 28 degrees C) led to increase of oxygen and to reduction of carbon dioxide tension in the blood. In case of marked hypothermia (24 degrees C) the blood gaseous concentration became less than at 28 degrees C, but remained above the initial level. This indicates prolonged preservation of adequate lung ventilation in the hypothermic organism.
