Cardiovascular-risk peripheral arterial tonometry system sensor
Definition
An pneumo-electronic device, typically designed as a proximal annular cuff incorporating plethysmography-based pneumatic bio-sensor, that is placed on a patient's finger during a reactive hyperemia test for the assessment of endothelial dysfunction (poor vasodilatory response) and arterial stiffness. It is connected to the cardiovascular-risk peripheral arterial tonometry system data processor and imparts a uniform pressure field to the distal two thirds of the finger, including the tip, to measure arterial pulsatile volume changes. This is a single-use device.
