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.
肢体的横截面积沿肢体长度方向变化。当使用阻抗体积描记法进行肢体血流研究时，这一点非常重要。必须仔细选择实际测量部位以及电极间距离，以避免低估血流值。对于成年受试者，电位电极之间的距离应小于10厘米。
