[Potentials of hyperbaric oxygenation in correcting central respiratory disorders in ischemic stroke].

Changes in central respiratory disorders under the effect of hyperbaric oxygenation (HBO) were studied in 29 patients in the acute stage of ischemic stroke. Spirography, tetrapolar rheography, and examination of the blood gas composition were carried out. Before HBO was begun, various disorders of the respiratory function were found (hyperventilation syndrome, periodical rhythms: Cheyne-Stokes respiration, alternating respiration, etc.). It was revealed that HBO session causes a normalizing effect on the respiratory function in central disorders of respiration: the Cheyne-Stokes rhythm was replaced at the end of the session by wave-like respiration which is biologically more adequate, the regimen of hyperventilation changed to normoventilation, etc. There was parallel improvement in the indices of central hemodynamics and the blood gas composition.
