The impedance rheograph has been shown to give values of blood flow consistent with a history of vascular insufficiency; normal limbs having a mean flow of 6.9 +/- 1.6 milliliters per minute per 100 milliliters of limb volume and diseased limbs having a proportionately reduced flow. The most reduced flow was found in those with rest pain or severe claudication, 1.7 +/- 0.8 milliliters per minute per 100 milliliters of limb volume. It is suggested that this technique may be useful clinically in assessing patients before treatment and, subsequently, as an objective evaluation of that treatment.
阻抗血流图已被证明能给出与血管供血不足病史相符的血流值；正常肢体每100毫升肢体体积的平均血流为每分钟6.9±1.6毫升，患病肢体的血流则相应减少。血流减少最明显的是那些有静息痛或严重间歇性跛行的患者，每100毫升肢体体积每分钟血流为1.7±0.8毫升。有人认为，这项技术在临床上可能有助于在治疗前评估患者，随后还可作为对该治疗的客观评估。
