ABSTRACT:
The venous patency of a human limb is assessed by measuring the venous outflow within a defined time interval after release of a forced blockage of the venous return to the heart and correlating it, where necessary, with the increased venous volume occasioned by the forced blockage. The volume changes and outflow rate are determined from electrical impedance measurements.
