关于利用恒流式阻抗图Kubicek公式测量心脏每搏输出量(SV)的一些问题,作者已经做过一些讨论。并根据由Kubicek公式求得的每搏输出量,分析了测量心脏每分输出量(CO)、搏指数(SI)、心指数(CI)、搏功指数(SWI)、心功指数(CWI)、总外周阻力(TPR)和血管顺度(C)等问题。有关心血管方面的恒流式阻抗图方法研究,国内外皆有一些报道,结果表明这种方法基本上是可行的,但还有待改进。 The authors have done some discussion about some of the problems with using the constant current impedance map, Kubicek’s equation, to measure cardiac stroke volume (SV). (CO), pacing index (SI), cardiac index (CI), stroke index (SWI), and cardiac function index (CWI) were measured based on the stroke volume determined by Kubicek’s formula , Total peripheral resistance (TPR) and vascular compliance (C) and other issues. There are some reports about the method of constant current impedance diagram of cardiovascular in China and abroad. The results show that this method is basically feasible, but it still needs to be improved.
