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.
Aggregate is designed to help you pre-process your data for more advanced signal analysis.
