Hypoxia resistance among the agedpatients with chronic obstructive lung disease: possibilities of using hypoxic trains

Age-related morphological and functional changes in the body lead to the development of arterial hypoxemia, tissue hypoxia and hypoxic changes, which reduces the body's resistance to hypoxia and contributes to the development of lung diseases, in particular chronic obstructive pulmonary disease (COPD) in the elderly. The aim of the study was to clarify the effect of interval normobaric hypoxic training (INHT) on hypoxia resistance in elderly patients with COPD. The survey showed that with an increase in bronchial obstruction, the shifts of blood saturation during hypoxia increase. The course of INHT leads to increased resistance to hypoxia, and also increases the ventilation response to hypoxia in elderly patients with COPD.
