Thereof, what is dependency Rubor?Dependent rubor is a fiery to dusky-red coloration visible when the leg is in a dependent position but not when it’s elevated above the heart. The underlying cause is peripheral arterial disease (PAD), so the extremity is cool to the touch. Normally, the foot and leg should remain pink with elevation and dependency.Secondly, how do you do the Buerger test? Buerger’s test. Buerger’s test is used to assess the adequacy of the arterial supply to the leg. It is performed in two stages. With the patient supine, elevate both legs to an angle of 45 degrees and hold for one to two minutes. Also question is, what is venous guttering? With elevation, the foot turns pale and there can be venous guttering (all the blood has drained out of the veins). When in a dependent position, the foot turns brightly red, called rubor, before returning to a normal pink color.What causes Rubor?Vasodilation and its resulting increased blood flow causes the redness (rubor) and increased heat (calor). Increased permeability of the blood vessels results in an exudation (leakage) of plasma proteins and fluid into the tissue (edema), which manifests itself as swelling (tumor).
