Abstract: Systems, methods, devices, and other techniques for assessing a fluid system of a patient. A fluid evacuator applies compression to a cuff on a limb of the patient, and measures a pressure of the cuff during the compression to obtain a pressure response curve. The pressure response curve can be analyzed to identify an incompressible region, where the incompressible region is a portion of the pressure response curve indicative of a bodily fluid having been substantially evacuated from at least a portion of the limb as a result of the compression.

Abstract: A vascular measurement system is provided to perform various types of peripheral vascular measurements to evaluate at least one of arterial blood flow and venous blood flow. The system includes a plurality of ports configured to connect a plurality of inflatable cuffs, an inflation device, a deflation device, and a volume measuring device configured to withdraw a predetermined volume of air contained in at least one of the first and second inflatable cuffs and resupply the predetermined volume of air into the at least one of the first and second inflatable cuffs.
