Change in Serotonin Level in the Organism in Cases of Hypoxia

This study was performed on both volunteers and test animals subjected to different extreme effects, causing different types of hypoxia. It is found that at high initial values of blood serotonin, the organism is more resistant to hypoxia. In individuals in whom the serotonin level is increased after extreme impacts, the hypoxic state is less readily sustained. The results of this study are used for determining the individual reactivity of an organism to hypoxia and for selecting for hire persons who may be required to work in extreme conditions.
