The toe brachial index (TBI) is calculated by dividing the systolic blood pressure at the toe by the systolic blood pressure at the arm. Using the Summit C025 Toe ABI Cuff - 2.5 CM ensures accurate measurement of toe systolic pressure, which is essential for reliable TBI assessment. A TBI value of 0.7 or higher is generally considered normal, while values below 0.7 indicate peripheral arterial disease (PAD) and impaired lower extremity blood flow.
