Neurovascular transduction

The term ‘neurovascular transduction’ is often used to describe the transduction of sympathetic nerve activity to regional vascular responses.

Autoregulatory index

Cerebral autoregulation can be evaluated by measuring relative blood flow changes in response to a steady-state change in the blood pressure (static method) or during the response to a rapid change in blood pressure (dynamic method).

Muscle sympathetic nerve activity

Muscle sympathetic nerve activity (MSNA) is recorded through the use of microneurography. This is the process of percutaneously inserting a tungsten microelectrode into a nerve to record action potentials.

Extract overview

Extract is a tool for data visualisation, selection, and analysis.

To load files clicking the file icon and navigate to the “Extracted” folder containing pre-processed files.

Processing additional signals

The Extras module is for labelling additional signals you wish to analyse. This can includes any signal that hasn’t already been specified under ECG, BP-Doppler, Ventilation, and Gases. Ensemble currently supports up to eight (X1-X8) additional  channels.

Processing ECG signals

Many cardiovascular analysis techniques are performed on a ‘beat-to-beat’ basis. This requires accurate defining of the cardiac cycle and is most accurately done using the ECG.
