[Mechanisms of adaptation effect of normobaric hypoxic therapy]

It was discovered that brain adaptation to long-term hypoxia operates primarily through lowering frequency of dominating spontaneous activity. EEG parameters can help in assessment of acute hypoxia and predict effectiveness of hypoxic therapy. Patients with definite response to rhythmic photostimulation in the range of alpha-activity tolerate hypoxia well. High presentation of slow waves in the pattern of the initial EEG, especially of teta-rhythm predicts formation of adaptive effect in hypoxic therapy.
