Rubor of Dependency AKA Buerger's Test
Purpose: Detect the presence or absence of peripheral arterial disease.
Procedure: With the patient supine, note the colour of the feet soles. They should be pink. Then elevate both legs to 45 degrees for more than 1 minute. Observe the soles. If there is marked pallor (whiteness), ischemia should be suspected. Next check for rubor of dependency.
Sit the patient upright and observe the feet.
Normal Result: The soles of the foot return to a pink color.
Abnormal Result: In PAD, the color changes from pale to pink and then progresses to purple-red or bright red. The longer dependent rubor takes to reappear, the worse the PAD. Rubor that appears in 25 to 40 seconds indicates severe ischemia
