Abstract:
In stroke patients we previously observed increases in the electrical brain activity during hyperbaric oxygenation which were quantified and documented by EEG-interval-amplitude-analysis system. The object of this study was to assess the relationship between EEG-interval-amplitude-analysis and the spectral-analysis. We approached this problem by evaluating EEG recordings obtained from stroke patients during their exposure to hyperbaric oxygen by both methods. The results showed: a) the influence of hyperbaric oxygenation over the EEG, b) a clear picture of quantitative indicators for electrical brain activity by these EEG-analysis-systems and c) a close correlation of both methods in evaluating EEG changes, apart from the more differentiated estimation of deltawave activity by the spectral-analysis.
