ABI Calculator
Calculate ankle-brachial index (ABI) for each leg using the highest arm systolic pressure and the highest ankle/foot systolic pressure.
Same calculator as ABI (alternate URL slug).
Measure the blood pressure in both arms and enter the higher of the two numbers below.
Highest arm blood pressure
Systolic pressure, which is the first number in a BP measurement (i.e., the 120 in 120/80).
mmHg
Highest pressure in right foot
Systolic pressure, which is the first number in a BP measurement (i.e., the 120 in 120/80).
mmHg
Right ABI
Highest pressure in left foot
Systolic pressure, which is the first number in a BP measurement (i.e., the 120 in 120/80).
mmHg
Left ABI
