Effect of local blood removal on skin resistance and potential.

Abstract

Using human Ss skin resistance alternating with skin potential were recorded simultaneously from both feet before, during and after exsanguination of 1 foot by an Esmarch bandage. The effects were assessed by comparing base levels and response amplitudes and wave forms under the test conditions. The results suggest: the mechanism underlying base resistance are separate from those underlying the skin resistance, the negative and positive waves of the skin potential response are produced by different neurophysiological mechanisms, there are differences in the local neurophysiological mechanisms underlying the skin resistance and skin potential responses, the effects of arterial occlusion are slight on skin resistance and not present on skin potential.
