[The dynamics of the autonomic indices in participants in the cleanup of the aftermath of the accident at the Chernobyl Atomic Electric Power Station at the stages of therapeutic hyperoxia].

Time-related course was studied of vegetative indicators during the hyperbaric oxygenation (HBO) sessions in 36 liquidators of the effects of the Chernobyl Nuclear Power Plant breakdown, who suffered from early forms of cerebrovascular insufficiency. Shown for the first time in therapeutic hyperoxia in the liquidators are features of the time-related course of vegetative regulation. Significant group particularities of changes in vegetative regulation have been stated, that suggest a different approach to the tactics of HBO employment. Those patients experiencing a higher tenseness of vegetative regulation demonstrated antecedents of toxic action of oxygen at minute 35 to 40 HBO. The employed vegetative indicators monitoring technology allowed the establishment of individualized hyperoxia doses, with the early signs of oxygen overdose being revealed in real time.
