Neuromonitoring Analysis (NMA)
The new TCD analysis software for cardiovascular physiology enables the differentiation of pathological and non-pathological findings with the aid of the Neuromon B.V. Doppler parameters and can be used, among other things, in surgery, anesthesia and intensive care.
The use of this innovative screening software allows physicians and healthcare professionals to quickly and reliably interpret the TCD signal in complex clinical situations, providing valuable information for further disease assessment and therapy control.

Since the introduction of Transcranial Doppler Sonography (TCD) in the early 1980s, high expectations have been placed on using it as a tool for hemodynamic monitoring of the brain. Many studies have been performed to document changes in intracranial flow velocity under various conditions.
Quantitative analysis within these studies has been based on parameters defined at the onset of TCD: peak systole, end diastole, and average flow rate, from which quotients were calculated, e.g. the resistance index (RI) and the pulsatility index (PI).
The company Neuromon has further developed the existing TCD indexes for advanced TCD parameterization, whereupon appropriate software for the NMA module has been specially designed for DWL devices.
These “new parameters” are based on the theory of arterial acceleration, which states that the arterial vasculature is not just a passive conduit, but brings the energy into the pressure wave of the heart. This pressure wave is expanded within the smooth muscle cells of the arterial walls and spreads as a peristaltic wave along the branches of the Arterial Tree.
