APG - Air Plethysmograph Brochure

The APG® Air Plethysmograph is a non-invasive diagnostic tool that quantifies the physiological components of chronic venous disease including: Chronic obstruction; Valvular reflux; Calf muscle pump function; Venous hypertension. The APG® Air Plethysmograph is the only system that measures true blood volume changes in milliliters and blood flow in milliliters per second. The APG® system senses pressure changes in a large cuff that extends from knee to ankle, which is calibrated in milliliters using a calibration syringe.
