ABI Calculator (Ankle-Brachial Index)

Calculates the Ankle-Brachial Index (ABI) based on user-inputted blood pressure readings taken at both the ankle and arm. The tool processes these measurements to determine a numerical ratio, which compares blood flow between the upper and lower extremities. A higher index generally indicates better circulation, while an abnormal or low result suggests potential narrowing of arteries in the legs, a condition known as peripheral artery disease (PAD). Medical professionals, students, and individuals managing cardiovascular health utilize this calculator for preliminary screening purposes. It provides a quick way to assess whether blood flow issues might be present without requiring specialized equipment on hand.
