Using a fine-tip oxygen microelectrodes the longitudinal gradients of oxygen tension (pO2) have been studied in small arterioles (with lumen diameter in control of 5 +/- 20 microm) and in capillaries of the rat brain cortex during stepwise decrease o

Acute anemia was shown to result in increase of pO2 in the wall of radial arterioles (with lumen diameter of 14.7 +/- 0.9 microm) and in the tissue near the studied arterioles, while decreasing as compared to control values at the distance 60 urn fro

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

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

The data obtained show that, at the initial stages of hypothermia, a decrease in the oxygen consumption and carbon dioxide production, cardiac output, and heart rate occurred in accordance with the temperature coefficient. Suppression of the tissue g

Artificial lung ventilation (ALV) was shown to restore the gas exchange in rats following their cooling to brain temperature 17.0-17.6 degrees C. However, the ALV proved ineffective if applied in 22.1 +/- 2.1 min after cessation of breathing. Fast wa

Gas exchange, oxygen transport and utilisation were shown to be limited at body temperature 17.5 degrees C in rats. Disturbances in the cardio-vascular system seem to be the main limiting factors telling on the above parameters in the course of spont

Changes of the oxygen consumption and the main parameters of the blood respiratory function as well as oxygen transport, were studied in Wistar rats under conditions of immersion hypothermia (with rectal temperature 15-13 degrees C). From the viewpoi

The arterial blood's pH, PCO2 and PO2 were shown to depend on the value of hematocrit in erythrocyte suspension in rats. The dependence can be described by the equation of linear regression except the oxygen tension value within its physiological ran
