The occlusion plethysmography (also vein occlusion plethysmography ) is an examination method in medicine , which is used for the diagnosis and follow-up of arterial and venous vascular diseases. The measurement of volume changes ( plethysmography ) in limbs allows statements to be made about the inflow and outflow of blood.
The measurements are usually carried out on the legs and, more rarely, on the arms, using different measuring sensors. Most frequently circumference measurements by mercury strain gauges performed infrequently with a slide members probe (after Dr. Ing. Jürgen Gutmann). Real volume measurements are possible with a water or air plethysmography.
The measurements are usually made on the calf, foot and toes. Targeted compression of veins and arteries during occlusive plethysmography enables the blood flow to be calculated semi-quantitatively. Both the blood inflow and thus the arterial blood flow and the blood return and thus the function of the venous system can be assessed.
