[Recovery of the oxygen consumption, oxygen transport, and cardiac activity after hypothermia followed by respiration and cardiac arrest in rats].
After a 1 hr deep prolonged immersion hypothermia, warming up of experimental rats in water (the temperature increase 0.25 degree C/min) entailed a complete recovery of all the parameters of gas exchange, haemodynamics, external respiration, and the blood. After a 3 hr hypothermia, under the same conditions of warming up, oxygen consumption, CO2 production, and 1 min blood volume were obviously decreased, and the animals died within 0.5-1.0 hr.
