ABI & TBI test taking by ES100V3, SD-45, and Bidop7

The ankle-brachial index (ABI) test compares your blood pressure measured at your ankle with your blood pressure measured at your arm.

A photoplethysmogram (PPG) is an optically obtained Plethysmogram, a volumetric measurement of an organ. The PPG Toe blood pressure and related Toe Brachial Index (TBI) are performed to assess the vascular condition of the foot by obtaining systolic pressures at the toe.
