[Results of studying pulse engorgement and regional vascular tonus during the flight of the 1st and 2d expeditions of the Saliut-6--Soiuz orbital complex].
The dynamics of pulse blood filling and regional vascular tone was studied in the crewmembers of 96- and 140-day flights aboard the station Salyut-6--Soyuz. Measurements were taken before, during and after flights, using a specially designed tetrapolar rheograph. Rheograms of the torso, forearms, legs, and rheoencephalograms of the right and left hemispheres in the frontal-mastoidal lead were recorded. The results showed that in zero-g the cosmonauts developed typical hemodynamic changes indicative of cephalad blood shifts. Thus, the hypothesis advanced and theoretically substantiated previously has found further support.
