[Age, gender and individually-typological characteristics of reaction to acute hypoxic exposure].

Individual pequliarities of hypoxic resistance, assessed by the response of cardiorespiratory system to acute normobaric hypoxia (10% O2), were studied in healthy subjects. Age changes in dynamics of blood oxygen saturation after the acute hypoxia are shown at level of separate sites curve SpO2 (phases of a delay, decrease and lifting). It is established, that at children sensitivity to acute hypoxia above, than at teenagers, and at teenagers above, than at adults. Higher lability of mental processes, sympathetic activity, and personal anxiety are associated with choleric temperament. Cholerics are characterized by slower restoration of blood oxygen saturation after the acute hypoxia compared with sanguine persons that we consider an indication of less hypoxic tolerance of the first group. We have developed the complex algorithm, dynamics describing dependence oxygen saturation in various phases of the hypoxic test, which can be used as a universal method of an estimation hypoxic stability at different groups of the population.
