1966年美国学者Kubicek 提出应用阻抗血流图方法计测心脏排血量并将此方法用于宇航生理的研究。此后各国学者对此项技术及原理引起关注,国内近年很快普及,但常用的参数及其公式共30余项。我院曾于1982年应用此法对179例健康飞行人员进行心脏功能16项参数正常值测算,认为对飞行人员的心脏功能评定有意义,但实际测算十分繁复。为此我们试用微电脑—苹果Ⅱ进行计算工作,使计算时间大大缩短,而且结果准确,目前国内尚未见此类工作报道,特介绍如下。
In 1966, American scholar Kubicek proposed to measure cardiac output by impedance flowgraphy and to apply this method to the study of space physiology. Since then, scholars from various countries have drawn attention to the technology and principle, and are popularized in China in recent years. However, there are more than 30 common parameters and their formulas. In our hospital in 1982, this method was used to measure the normal values of 16 parameters of cardiac function in 179 healthy pilots, which is of significance to the evaluation of the cardiac function of pilots. However, the actual measurement is very complicated. To this end, we try the microcomputer - Apple Ⅱ computing work, so that the calculation time is greatly reduced, and the results are accurate, at present there is no such work reported in China, introduced as follows.
