SCHILLER’s Pulse Wave Analysis (PWA): circadian central haemodynamics and blood pressure measurement in one SCHILLER presents the first solution that combines the non-invasive, cuff-based precise auscultatoric and the reliable oscillometric measurement to generate a 24-hour profile of stiffness parameters like pulse wave velocity, augmentation index as well as central and peripheral blood pressures. Based on individual arterial behavior, it is now possible to evaluate the risk of developing a cardiovascular disease and helps to prevent severe organ damage. As an autonomic operating device, it perfectly integrates into ABPM routine - no specially trained operator is needed for PWA measurements. The algorithm was used in several studies, including comparisons with the gold standard (invasive blood pressure measurements); it is therefore recommended by the ESH/ESC in their guidelines.
