[Reactions of cerebral vessels to hyperbaric oxygenation in the normal state and in patients with cerebral ischemia].

During initial sessions of hyperbaric oxygenation (HBO), the reduction of the pulse blood content in health (with no cerebral injury) is not pronounced and does not reach the significant level whereas in the course of final sessions it does not almost manifest itself. In contrast to that, in the main group of patients (with sequels of ischemic insult), the above reaction manifests itself more clearly, being statistically significant both in the course of initial and final HBO sessions, which demonstrates greater vasoconstrictor preparedness. That reaction is especially remarkable in the hemisphere of predominant injury (HPI) whereas in the relatively preserved hemisphere, it is slightly weaker and occupies as if an intermediate place between the HPI and normal.
