To calculate the Ankle Brachial Index (ABI) for peripheral arterial disease (PAD).

Use to calculate the Ankle Brachial Index (ABI) for peripheral arterial disease (PAD). The two formulas used are: Right ABI = Highest pressure in right foot / Highest pressure in both arms Left ABI = Highest pressure in left foot / Highest pressure in both arms Interpretation ABI value Vessel structure interpretation Recommendation 1.0 - 1.4 Normal None 0.9 - 1.0 Acceptable None 0.8 - 0.9 Some Arterial Disease Treat risk factors 0.5 - 0.8 Moderate Arterial Disease Refer to vascular specialist <0.5 Severe Arterial Disease Refer to vascular specialist
