title: [Asymmetry of oxygenation and deoxygenation of a thick blood layer].
abstract: A cell for convoluted blood film was used to study the processes of oxygenation and deoxygenation in a 5-mm deep layer of whole blood contacting peripherally with a gas medium. It was shown that nitrogen replacement by oxygen or vice versa with steady 5% CO2 accelerates significantly blood oxygenation but not deoxygenation. On consideration of possible reasons a conclusion has been made in favor of geometric rather than physical-chemical factors. This phenomenon should be accounted for when encountering with stagnation state in organism, vascular occlusion and other circulation disorders.
