Abstract

Two years ago we presented our studies on photoelectric plethysmography [1]. One of the conclusions was that the amplitude of the finger plethysmogram, in contrast to that of the ear, is very sensitive to changes in smooth-muscle tone of the arteriolar walls. The main reason for the strong reactivity of the finger plethysmogram is that the vascular walls in the finger are only a-sympathetically innervated [4]. We also presented our experience with a method to measure blood pressure in the finger continuously and yet non-invasively [2] with the new Finapres of Wesseling et al. [7]. We showed that during peripheral vasoconstriction systolic blood pressure in the fingers rise more than that in the upper arm, whereas it decreases more during peripheral vasodilation. It was also shown that systolic blood pressure in the radial artery reacted like that in the finger.
