Analysis and Monitoring

HDO PULSEWAVE ANALYSIS (PWA) WHAT IS IT ALL ABOUT?

Non-invasive PWA allows, for the first time, to look for changes in SVR = Systemic Vascular Resistance (vasodilation, vasoconstriction, arteriosclerosis, etc.), to judge Stroke Volume (SV) and Stroke Volume Variances (SVV). This is particularly of interest in patients with arrhythmias or any heart condition such as, but not limited to, mitral valve insufficiency, dilated and hypertrophic cardiomyopathy.

PWA in combination with blood pressure, is a very sensitive indication of cardiac performance, helpful during anesthesia, for diagnosis of disease as well as regarding the need and intensity of treatment and treatment control.

In particular SVR is new information: now easily available to the front line practitioner. With only 1 day training, one can successfully learn how to interpret the pulse waves and what action needs to be taken. Thus much faster and easier than ECG!

The resulting information shows promising results against invasive Gold Standard for SVR, SV and SVV.
