Enter the ankle systolic pressure (mmHg) and the brachial systolic pressure (mmHg) into the Calculator. The calculator will evaluate the Anke Brachial Index. 

Anke Brachial Index Formula



  • ABPI is the Anke Brachial Index ()
  • ASP is the ankle systolic pressure (mmHg)
  • BSP is the brachial systolic pressure (mmHg)

To calculate Anke Brachial Index, divide the anke systolic pressure by the brachial systolic pressure.

How to Calculate Anke Brachial Index?

The following steps outline how to calculate the Anke Brachial Index.

  1. First, determine the ankle systolic pressure (mmHg). 
  2. Next, determine the brachial systolic pressure (mmHg). 
  3. Next, gather the formula from above = ABPI = ASP / BSP.
  4. Finally, calculate the Anke Brachial Index.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

ankle systolic pressure (mmHg) = 40

brachial systolic pressure (mmHg) = 45
