ABI Calculator – Ankle Brachial Index
Calculate Ankle-Brachial Index to assess peripheral vascular disease
Clinical Formula: The ABI for each leg is calculated as $\text{ABI} = \frac{\text{Highest Ankle Systolic Pressure}}{\text{Highest Arm Systolic Pressure}}$. Normal resting ABI ranges between $1.00$ and $1.40$. Enter your blood pressure measurements below.
