Venous testing and vascular assessments from induced anatomical fluid flow

One or more computer-readable storage media encoded with instructions that, when executed by one or more computers, cause the one or more computers to perform opera rations comprising:

• applying with a fluid evacuation system, compression to a cuff on a limb of the patient,
• measuring a pressure of the cuff during the compression to obtain a pressure response curve;
• analyzing the pressure response curve to identify an incompressible region, wherein 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;
• and
• using information about the incompressible region of the pressure response curve (i) to screen for one or more problems with the fluid system or (ii) to evaluate an efficacy of the fluid evacuation system in evacuating the bodily fluid from the limb of the patient.

A system, comprising:

• a pump configured to increase pressure of a working fluid in a cuff during a compression action;
• a valve configured to release pressure from the cuff during a decompression action;
• a pressure transducer configured to measure a pressure of the working fluid in the cuff;
• and
• one or more controllers configured to actuate the pump and the valve to control a level of pressure of the working fluid in the cuff via compression and decompression actions based at least in part on measurements from the pressure transducer.
