Forming amplitude-integrated EEG trends (aEEG)
aEEG is a special algorithm for processing and visualization of EEG meant for continuous monitoring the dynamics of the EEG amplitude.

The following is also displayed on aEEG trends:

• A graph of aEEG suppression manifestation is lower than minimal threshold of aEEG amplitude.
• Classification of aEEG patterns.

The following is calculated and displayed below aEEG trend:

• aEEG events panel – "burst", "suppression" and "remains".
• A graph of aEEG bursts dynamics.
• A graph of aEEG suppression dynamics.

For more details, see "Encephalan-CFM" software

Channels configuration library allows using

• Simplified 1-channel variant (for cerebral functions monitoring in newborns).
• 2-channel bipolar montages with an common sagittal electrode or separated by hemispheres EEG derivations and combinations of these montages with ECG, EMG and EOG signals.
• 4-channel monopolar montages, which allow conducting reference reconstruction.

Additional types of analysis and visualization of amplitude-integrated EEG trends (aEEG)

• Trends of density spectral array for operative evaluation of spectral content dynamics and EEG power.
• 3D presentation of compressed spectra.
• Trends of spectral power indices by range (SPIR).

EEG analysis and service options
Functional capabilities of "Encephalan-EEGR" software:

• Visual analysis of current EEG changes during monitoring.
• Electrode impedance and cross-electrode potential control and record during electrodes attachment, real EEG record and for subsequent analysis.
• Manual and automatic markers setting during EEG record and analysis. Markers are displayed in a special window for quick switch to corresponding record fragment.
• Data printing. Print manager allows easily preparing and printing analysis results of cerebral functions monitoring, results in tabular and graphical form, and conclusions.
• Storage of studies in the "Cardfile" database with the ability to export and import studies, as well as data backup to external media.

Option of simultaneous cerebral functions monitoring in several patients in ICU.

Data on each patient are displayed in a specified window. Any window may be displayed in full-screen mode for detailed analysis. Option of videomonitoring synchronized with brain electric activity monitoring.

Information of patient transceiver-recorder (up to 4 pcs) is transmitted via wireless channels to central station.

Videomonitoring synchronized with recorded data (videomonitoring kit and software "Encephalan-Video" are required) allows detecting movement and seizure activity that is important for differential diagnosis of the CNS functional state and detection of epileptiform activity.

Optional "Encephalan-NM" Software allows observing trends of such diagnostically significant parameters as median and weighted average frequency, spectral edge frequency, effective bandwidth, asymmetry index and others, synchronously with CFM trends.

Additional wireless modules and sensors expand a set of trends with such parameters as heart rate, breathing frequency and depth, muscle tense, movement activity, etc.

• "HRV" Software for Heart Rate Variability Analysis provides evaluation of autonomic nervous system (ANS) state on the basis of HRV analysis.
• "Encephalan-EP" Software for EP-studies provides long latency evoked potentials (EP) studies to stimuli of different modality (visual, auditory, somatosensory) with stimulators.
• "Encephalan-MPA" software for multiparameter analysis of signals from polygraphical channels in combination with EEG signals (if additional wireless devices and sensors are purchased).
• "Encephalan-AVS" Software Suite for EEG and EP Studies Using Audiovisual Stimulation. Software provides flexible generation and playback of scenarios of cognitive stimulation using graphic images, audio files and text information as stimuli.
• "Encephalan-VLFA" Software for Analysis of Very Low Frequency Activity. Software provides analyzing of very slow EEG responses simultaneously with recording of EEG by the same derivations.
