Neurovascular transduction
The term ‘neurovascular transduction’ is often used to describe the transduction of sympathetic nerve activity to regional vascular responses.
The term ‘neurovascular transduction’ is often used to describe the transduction of sympathetic nerve activity to regional vascular responses.
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 (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 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.
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.
The Gases module is designed to detect inspired and end-tidal gas concentrations of O2 and CO2 respectively.
BP-Doppler module is designed for rapid identification of beat-to-beat systolic, diastolic, and mean values from pulsatile waveforms.
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.
