OXYGENATION OF BRAIN TISSUES DURING AIR AND OXYGEN RESPIRATION WITH AN ADMIXTURE OF CO2,

Abstract

Conclusions: The oxygen tension in brain tissues (cortex and subcortex) during air respiration with 5 and 10% of CO2 increased as compared with the original up to 125 and 160%, respectively. Pure oxygen respiration caused an increase of pO2 in the brain tissues by 1.5-2 times. The gas mixture, which consisted of 95-90% of 02 and 5-10% of CO2, increased the oxygen tension in the brain tissues by 3-4 times. The obtained data showed that in complex with other methods of investigation, the polarographic determination of the oxygen tension can be a valuable criterion in determining the process of oxygenation of brain tissues.
