[Effect of hyperoxic gas mixtures on the mass transfer of oxygen through the hematoparenchymatous barrier].
In 21 rabbits, the process of oxygen mass transfer through the hemato-parenchymatous barrier conditions of hyperoxia with 80% O2 in inhaled mixture, was shown to decrease 6-7-fold and to be determined by a high partial O2 pressure rather than physical properties of accompanying gas. The protective properties of hyperbarism are equally evident both in nitrogen-oxygen and in helium-oxygen mixtures, restricting the increment of O2 tension in tissues.
