HDO Pulse Wave 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) , which is particularly
of interest in patients with arrhythmias or any heart condition
but not limited to mitral valve insufficiency , dilated and
hypertrophic Cardiomyopathy. PWA in combination with
blood pressure is a very sensitive information on 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 a new information, easily available now to
the front line practitioner. With only 1 day training, one can
successfully learn how to interpret the pulse waves and what
consequences need to be taken. Thus much faster and easier
than ECG!
The resulting information could be proven reliable against
invasive Gold Standard for SVR, SV and SVV. (Egner, ECVIM
