METHOD FOR REDUCING CHRONIC TISSULAR HYPOXIA Russian patent published in 1999 - IPC

FIELD: medicine. SUBSTANCE: method involves applying a course of treatments like periodic hypercapnic gas mixture inspirations mainly based on atmospheric air in keeping nitrogen contents in composition unchanged. Carbon dioxide initial concentration is to be measured in patient in rest state in arterial blood. The quantity of 0.05-0.35 times the measured one is taken as carbon dioxide concentration in primary gas mixture for inspiration. Carbon dioxide concentration is increased in the primary inspiration gas mixture by 0.003-0.03 of initial carbon dioxide concentration in patient arterial blood in rest state in every following treatment. The course is applied until arteriovenous difference in oxygen contents reaches maximum value. EFFECT: reduced tissue hypoxia; respiration center readaptation.
