    Notes: Abstract Electrode design and electrode positioning are important factors in blood flow measurements using impedance plethysmography. Optimal electrode type and accurate positioning will decrease measurement errors and improve the signal-to-noise-ratio. Disk electrodes were found to be superior to tape electrodes because of their better skin-electrode stability and because they prevent limb compression. The distance between current electrodes and potential electrodes should be greater than 2·3 R (disk electrodes) and 1·5 R (tape electrodes) to avoid the influence of the so-called diffusion resistance (R is the radius of the limb at the electrode site).

    Impedance plethysmography for blood flow measurements in human limbs (1992)
    Springer
    Medical & biological engineering & computing 30 (1992), S. 518-524 
    Details
    ISSN: 1741-0444
    Keywords: Blood flow in human limb ; Cross-sectional area ; Impedance plethysmography ; Strain gauge

    Topics: Biology , Chemistry and Pharmacology , Medicine
    Notes: Abstract The cross-sectional area of a limb varies along the extremity. This is of great importance when impedance plethysmography is used for limb blood flow studies. The actual measurement site, as well as the interelectrode distance, must be carefully selected to avoid underestimation of the blood flow value. The distance between the potential electrodes should be less than 10 cm for an adult subject.
