BR-102 PLUS PWA
SCHILLER’s Pulse Wave Analysis (PWA): circadian central haemodynamics and blood pressure measurement in one
BLOOD PRESSURE ALL-ROUNDER
SCHILLER introduces 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 and central and peripheral blood pressure. Based on individual arterial behaviour, it is now possible to evaluate the risk of developing a cardiovascular disease.
PROVEN QUALITY
This algorithm has been fully validated in several studies, even comparisons with the gold standard: invasive catheter BP measurement.
“... algorithm, using brachial cuff-based waveform recordings, is suited to provide a realistic estimation of central systolic pressure.”
“The results agree with common accepted tonometric measurements. Its application is easy and for widespread use.”
SCHILLER …
- keeps the cuff pressure as low as possible for increased patient comfort. PWA is performed on diastolic level.
- provides a 48-hour profile and not just spot measurements (tonometric method).
- includes the auscultatoric measurement which is much more reliable.
- has comprehensive validation studies.
- offers a blood pressure measurement device fully integrated in the wide range of SCHILLER diagnostic products, with seamless connectivity to SEMA data management systems and to HIS.
- has a user-friendly interface with colour display.
HOW IT WORKS
The analysis is based on the combination of auscultatoric/oscillometric blood pressure measurement and pulse contour analysis, and provides information about arterial behaviour as well as pulse wave velocity. The stiffer the arteries, the quicker the pulse wave, which increases the risk for cardiovascular disease. The age of the small blood vessels is determined using the augmentation index, an indicator of alterations.
Since guidelines recommend using PWA for risk stratification but provide no critical value, SCHILLER has a proactive solution: the patients’ readings of PWV, AIx and pRes are matched with other patients based on population studies 1. This gives an idea of how the values perform compared to other people.
WHY SCHILLER PWA
Medical point of view
- Significantly improve cardiovascular (CV) risk assessment
- Close correlation between stiffness parameters and coronary heart disease
- Prevent end organ damage due to hypertension
- More effective and more specific therapy – some hypotensive drugs may also increase arterial stiffness
- Differential diagnosis (peripheral resistance increased, stiff arteries or increased cardiac preload)
Economic point of view
- Increase in diagnostic precision
- No additional effort – part of a standard Ambulatory Blood Pressure Monitoring (ABPM)
- Emerging scientific publication possibilities
- No specially trained operator needed
- Reimbursement in several countries available, more and more countries joining
Both the ESH (European Society of Hypertension) and the ESC (European Society of Cardiology) are convinced of the huge potential of PWA and have recommended its use in their guidelines since 2007.
