Abstract

The circulatory system of man is very well adapted to changing conditions of orthostatic load. Depending on the position within the earths gravitational field, blood volume and body fluids are shifted between legs and upper part of the body. In the conditions of microgravity, hydrostatic pressure within the arterial system is equilibrated, creating a state which cannot be observed on the ground, but which can be simulated to some extent by a -4&#00B0; to -7° head down tilt. The investigation of the physiological changes observed in microgravity within the circulation was one of the purposes of the experiments PULSTRANS and SLEEP, which were part of the Austrian-Russian space flight AUS-TROMIR in October 1991.
