[Elastic properties of the arteries and hemodynamics of the human extremities during postural exposures].
A non-invasive method was applied to estimation of elastic properties, the effective inner radius, blood pressure, and a number of other parameters in limb arteries of healthy men under postural effects. The changes in elastic properties of arteries were shown to occur only in the lower limbs where gradient of hydrostatic pressure changed during the examination. In the arms, where this gradient is practically absent, elastic properties of arteries remained the same. The data obtained indicate that gradient of hydrostatic pressure is responsible for the changes observed.
