Studies of Venous Return

　Ⅰ．　METHOD FOR MEASURING THE VENOUS RETURN

　To measure venous teturn implies to esti—mate the venous flow. To measure venous return in a certain venous system provides information for the value of venous flow from the organ or the tissue to which the system is the tributary. Methods for the venous flow measurement has been illustrat—ed in detail in the monograph "Venous Re—turn" by Brecher^1）. For the application of above method it is hardly possible to measure consecutively to determine relative venous flow from the various organs of an indi—vidual.
