[The evaluation of the efficacy of adaptation to intermittent normobaric hypoxia as a method for treating hypertension].

Clinical and functional condition was examined for 75 patients with essential hypertension stage I and II who had developed adaptation to normobaric cyclic-fractionated hypoxia. The latter was produced by gas hypoxic mixture (10% oxygen, 90% nitrogen) in its inhalation. A pronounced positive effect of such treatment modality was registered in 86.7% of the patients and persisted for 6 months and more in 84.3%. A normal correlation was achieved of cardiac ejection to peripheral vascular resistance, this reducing arterial pressure. An optimal hemodynamic response arose to the hypoxic effects which also improved psychoemotional status of the patients.
