尽管心阻抗图描记术在20余年前就已发展到目前的状况。但在加强监护病室(ICU)中还远未得到广泛的普遍应用。过去的几年里,人们对应用这种技术在ICU内进行无损监测的兴趣大为增加,但尚无严格的临床检验。血流动力学监测常规技术目前对ICU病人的血流动力学参数均应用有心导管进行常规床旁监测,这种技术通常可能得到心输出量和肺毛细血管嵌顿压(Pw)。一般情况下,Pw可精确反映左房压和左室充盈压。
Although heart impedance mapping has evolved to the current state more than 20 years ago. However, it is far from being widely used in intensive care unit (ICU). In the past few years, there has been a great increase in interest in using this technique for non-destructive monitoring within the ICU, but there is no strict clinical test. Conventional techniques for hemodynamic monitoring Cardiac output and pulmonary capillary pressure (Pw) are usually available with conventional catheterization for routine bedside monitoring of hemodynamic parameters in patients with ICU. Under normal circumstances, Pw can accurately reflect left atrial pressure and left ventricular filling pressure.
