Monitoring Peripheral Arterial Disease (VIDEO)

Optica

Caption

This movie compares the blood flow dynamics in a cross-section of the foot between a healthy individual and a diabetic patient with PAD. Differences are clearly visible in both the amplitude and speed at which the blood reacts to two applications of a pressure cuff (60 and 120 mmHg) around the thigh.
