In anaesthetised cats, the arterial input impedance in combination with seven-element lumped-parameter model was used to estimate the resistance change in arteries of different caliber. The results show that the method gives reasonable estimations of changes in hydraulic resistance of arterial vessels of different caliber. We found that the method of vascular input impedance permits to reveal and assess quantitatively local constrictions and dilations as well as hemodynamically insignificant stenosis of conduit arteries.
在麻醉猫身上，将动脉输入阻抗与七元件集总参数模型相结合，用于估计不同管径动脉的阻力变化。结果表明，该方法能够合理估计不同管径动脉血管水力阻力的变化。我们发现，血管输入阻抗法能够揭示并定量评估局部收缩和扩张以及输送动脉中血流动力学上无显著意义的狭窄。
