The effect of hypothermia and oxygenation on the cardiorespiratory system in man exposed to experimental weightlessness

: It has been established that hypothermia in experimental weightlessness, as compared to normal conditions, was characterized by a considerably smaller deficit of erythrocytes in the energy balance and reduced gas exchange level, despite unidirectional changes in hemodynamic parameters. Unlike in hypothermia, an increase in oxygen concentration in the inhaled gas mixture had no noticeable effect on the parameters of the cardiorespiratory system studied.
