Since clinical diagnosis of DVT is often inaccurate, it has become accepted that an objective means of diagnosing clot in the deep venous system becomes critically important in the management of these patients. The venous Doppler examination monitors the velocity of blood flowing through a particular vein. Doppler probes in the 5 to 10 mHz range are routinely used. Respiratory variation is a normal finding due to a diminished flow signal during inspiration, followed by a progressive increase in flow signal during expiration. Characteristics of the spontaneous flow signals are the most important part of interpreting the venous Doppler examination. In addition, the response to distal or proximal compression (augmentation) adds important information to the interpretation; however, the response during any augmentation maneuver depends on the rapidity of compression, the force of compression, the quantity of blood in the veins at the time of compression, and the distance between the Doppler probe and the compression point. Phleborheography is a six-channel volumetric plethysmographic technique that monitors volume changes in the lower extremities associated with respiration and foot and calf compression.
