Venous plethysmography: measuring techniques and normal values.
A fixed procedure of strain gauge plethysmography in a control population aged between 20-30 years allows normal values for venous parameters (venous distensibility, emptying, and resistance) and capillary filtration coefficient, to be determined. High speed recording reveals two phases in venous emptying, one passive, purely elastic, and a second active phase, resulting from venous constriction.
