50年代初,Nyboer氏导出了阻抗与容积间的关系式,60年代Kubicek首先成功地把阻抗法用于心输出量的测量。嗣后,各国学者从各个不同的角度对Kubicek方法进行了广泛深入的研究。这
In the early 1950s, Nyboer’s derived the relationship between impedance and volume. Kubicek first used the impedance method in the 1960s to measure cardiac output. Subsequently, scholars from various countries carried out extensive and in-depth research on Kubicek’s method from different perspectives. This
