Abstract

Static and dynamic (beat-to-beat) arterial viscoelastic properties were measured noninvasively in human fingers and forearms. The volume change and pressure change were detected simultaneously by admittance plethysmography and by sphygmomanometry using the vascular unloading technique in the index and middle finger, or vice versa. These simultaneous measurements were also made on the forearms of one side and the fingers of the other side. The arterial viscoelastic properties in these segments could be successfully determined at different transmural pressure levels from 0 mm Hg to around the mean arterial pressure.
