[Analysis of the rebound phenomenon during outflow in plethysmography following programmed venous occlusion].
The venous outflow curve obtained using strain gauge plethysmography (Periflow JSI) frequently displays a slope change which modifies the classic exponential pattern: The semi-continuous arterial blood flow measurement together with an ECG-triggered plethysmography let the authors show the arterial origin of this slope change they called "the rebound phenomenon". Venous occlusion induces an ischemia which creates a reactive hyperemia when the venous blood current is let free. All the venous outflow curves stem from both a venous and arterial phenomenon. This latter may sometimes be of importance and has to be considered in plethysmography studies.
