Photoplethysmography (PPG)

Photoplethysmography (PPG) is an examination comparable to the ankle-brachial index except that it uses a very tiny blood pressure cuff around the toe and a PPG sensor (infrared light to evaluate blood flow near the surface of the skin) to record waveforms and blood pressure measurements. These measurements are then compared to the systolic blood pressure in the arm.
