[Venous blood circulation in the crew of the Saliut-5 orbital station]

Studies of venous circulation were continued in the space crewmembers of the orbital station Salyut-5. New data which demonstrated again that weightlessness induced symptoms specifically assoicated with blood redistribution and pressure increase in the jugular veins were obtained. It is suggested to further the studies of venous circulation and regional hemodynamics aimed at determining the time and degree of human body adaptation to weightlessness.
