An increasing number of authors devote their work to the study of circumpolar hypoxia. Conclusions about the mechanisms of its occurrence based on the results of the work are ambiguous. Some researchers believe that hypoxia in the North is due to oxygen defi ciency and rarefi ed air. Others believe that hypoxia in the North is not associated with a decrease in the partial pressure of oxygen in the air, since it diff ers little from other regions, except for the highlands. Also, a number of authors are of the opinion that circumpolar hypoxia is associated with increased tissue oxygen consumption. It is believed that the main cause of hypoxemia in the North is a violation of the diff usion of oxygen and carbon dioxide through the alveolar-capillary membrane of the lungs. It has been established that the genesis of circumpolar hypoxia is of a mixed nature and is a systemic phenomenon, which must be taken into account when developing measures to accelerate adaptation for living in the North.
