[Experimental evaluation of the relationship between lesser circulation engorgement, the state of water-salt metabolism and the orthostatic reactions in man].
In 12 series of short-term (4.5 hour) experiments the exposures that influenced the blood distribution relative to the long axis of the body (postural changes, lower body excessive pressure, lower body negative pressure, axial loads) were studied. A close correlation between the blood flow in lung capillaries, water losses and orthostatic responses was established. The correlation was dysproportional when LBEP or LBNP was applied in certain postures. This may be attributed to the effect of these exposures on vessel compliance.
