[A respiratory syndrome in patients with neurocirculatory dystonia].
The purpose of the work was to evaluate the compensatory and adaptive possibilities of oxygen transport systems in moderate hypoxic hypoxia to define the sensitivity to hypoxia of patients suffering from neurocirculatory dystonia (NCD) with the respiratory syndrome and to elaborate training therapy methods. 40 patients suffering from cardial NCD were examined. Of these, 23 complained of dyspnea. The general hypoxemic test (GHT) was used; parameters of external respiration, hemodynamics, gas composition of blood, and the content of oxidation substrates were examined. Analysis of the clinical picture of respiratory disorders in patients with cardial NCD revealed the differences in their nature. In addition to psychogenic factors of dyspnea, of importance was a decrease in the compensatory and adaptive possibilities of the body as regards hypoxia, which occurs in mental, physical stress, changes in meteorological conditions, in closed premises, and in vegetovascular crises.
