[Developing the methodology of examining the lower limb veins in cosmonauts for the space medicine practice].
The article centres on development of a methodology for evaluating the function of lower limb veins of cosmonauts in microgravity. The whys and wherefores of the choice of occlusive plethysmography equipment and procedure are explained. Much place is given to arguments for the requisite body and limb positioning during venous plethysmography pre launch and on return from space flight. To minimize the gravity effect on venous blood flow, the body should be in the level position and the calf aligned with the hydrodynamically indifferent point. Determining the type of test occlusion, occlusion adjustments, venous parameters of interest, and data processing procedure constitute the methodology.
