Impedance plethysmography: evaluation of a simplified system of electrodes for the measurement of blood flow in the lower limb.
Venous occlusion plethysmography was used to measure the flow of blood into the lower limbs of 30 normal volunteers. An impedance plethysmograph, using disposable point electrodes, was compared with a mercury in Silastic strain gauge plethysmograph in 20 subjects. The effect of changes in the configuration of the point electrodes was studied in 10 subjects. Impedance plethysmography was shown to be reproducible, and one particular configuration of point electrodes was shown to be superior to the others.
