Plethysmographic Measurement of Venous Flow Resistance and Venous Capacity in Human Legs. Part Two: Normal Values Related to Age, Sex and Site of Measurement

Abstract

This report presents normal values of venous flow resistance ( Rv) and venous capacity (C10) as measured in human limbs by strain-gauge plethysmography. No age dependency was found for either parameter. Rv was lower in males than in females and lower in left legs than in right legs. C10 was higher in males than in females and higher in left than in right legs. The left-right and sex dependency of the parameters cannot be explained by differences in limb volume. Correlations between selected parameters are presented.
