Abstract
Of the various factors entering into the problem of circulatory dynamics the most important is the rate of blood flow. This can be determined experimentally by Ludwig'sStromuhror some of its various modifications. More recently T. G. Brodie1has estimated the blood flow in an organ by suddenly occluding its efferent vein and measuring the change of volume by an oncometer. Under these circumstances the arterial blood enters the organ with undiminished speed at first, but soon the flow is retarded by the rise of pressure in the veins and capillaries. The organ therefore swells rapidly at first and progressively more slowly. The earliest portion of this curve represents the rate at which the blood enters under normal conditions. Brodie has shown that this method gives as reliable results as theStromuhr. It is applicable only to organs from which all efferent blood can beThis publication has 1 reference indexed in Scilit:
