[Recovery of the gas exchange and oxygen transport after long-term hypothermia in rats].
After a deep prolonged hypothermia, fast warming up of experimental rats (0.26 degree C/min) to the body temperature 35-36 degrees C entailed recovery of the heart rate, blood pressure, 1-min blood volume, oxygen consumption in rats. However, in the process of warming up, cardiac output, function of the left ventricle, oxygen consumption and the CO2 production were decreased. Acidosis and haemoconcentration following a 3 hr prolonged hypothermia were reversible.
