Abstract
The model with perfusing pump revealed that the amplitude and form of the rheographic signal was the function of two simultaneously acting factors: the pulse enhancement of fluid volume in the model and the speed of the fluid flow. This necessitates that causes of circulation changes in the model can only be determined considering changes in plethysmogram and pressure in the outflow system. Using these parameters, a deciding role of alternative determination of the causes of circulation disturbance, is suggested.
摘要
带有灌注泵的模型显示，流变图信号的幅度和形态是两个同时起作用的因素的函数：模型中液体体积的脉冲增强和液体流动速度。这就使得只有考虑到体积描记图和流出系统压力的变化，才能确定模型中循环变化的原因。利用这些参数，有人提出了交替确定循环紊乱原因的决定性作用。
