About the Ankle-Brachial Index Calculator
The Ankle-Brachial Index (ABI) Calculator is a valuable tool for assessing peripheral arterial disease (PAD). It calculates the ratio of blood pressure in the ankle to blood pressure in the arm to determine blood flow and vascular health. ABI is critical for diagnosing and monitoring PAD and can also indicate cardiovascular risks. This calculator computes the ABI for both the right and left legs based on systolic blood pressure values and provides a detailed step-by-step solution and visual representation of the results.
Formula
Right ABI = Highest Right Ankle Systolic Pressure / Highest Brachial Systolic Pressure
Left ABI = Highest Left Ankle Systolic Pressure / Highest Brachial Systolic Pressure
How to Use the Calculator
To use the ABI Calculator, input the highest systolic blood pressure of the arm and the respective highest systolic pressures for the right and left ankles. The calculator will automatically compute the ABI values for both legs using the provided formula. Results are displayed in a vertical table, along with a detailed step-by-step explanation and a distribution polygraph chart.

FAQs
What is the Ankle-Brachial Index?
The Ankle-Brachial Index (ABI) is a diagnostic tool that measures blood flow by comparing blood pressure in the ankles and arms to assess vascular health.
How is ABI calculated?
ABI is calculated using the formula: Right ABI = Right Ankle Pressure / Brachial Pressure, and Left ABI = Left Ankle Pressure / Brachial Pressure.
