    Plethysmography


    A plethysmograph is an instrument for determining and registering variations in the size of an organ or limb. The diagnosis of vascular disease is done with several types of plethysmograph, each with advantages.
    An infrared sensor is placed on the skin of the limb, which detects skin color changes that occur with each heartbeat
