Full-term infant, age 8 days.

Background activity: medium amplitude constant pattern, absence of “burst-suppression” pattern, presence of epileptiform bursts, theta-activity on the spectral indices trends is evident, there are signs of short-term transition to deeper sleep stages (sinusoid extension of aEEG zone on EEG)
Pattern relates to nominal normal because it has no pathological signs.

Pattern with flat EEG (< 5 µV) with periodical bursts of high – amplitude activity shows the most severe brain damages with poor prognosis and high possibility of significant neurological defects forming when a patient survives.

Continuous pattern with low amplitude (< 10 µV) often goes with hypoxic-ischemic encephalopathy (HIE) (severe or of moderate severity), meningitis etc.

Continuous pattern with normal amplitude. High aEEG value > 10 µV, low values > 5 µV. If there are no pathological signs (see other examples) this pattern is considered to be normal.

"Burst-suppression" pattern often goes with severe neurological diseases of neonatal period, comatose states, heavy asphyxia, encephalomeningitis, metabolic disturbances.

"Saw-tooth" pattern corresponding to status epilepticus.

Preterm infant, 7 days hypoxic-ischemic encephalopathy and jaundice

On the left there are controlled physiological signals (EEG, ECG and PPG SpO2).
On the right there are results of study analysis (from top downward: compressed spectrum, aEEG, spectrum indices).
Additional window contains videorecord.
EEG signals and aEEG trends contain the pattern "burst-suppression" with low values of EEG amplitudes and periodical bursts which is characteristic of neurological diseases of neonatal period, heavy asphyxia and metabolic disturbances. Low-frequency slow-wave activity within delta-1 range predominated on range Power spectrum index trends.

Patient with episyndrome

Against the background of significantly disorganized non-regular alpha-activity the discharges of epileptiform activity are recorded (the left picture) which indicates that the patient has episyndrome.
Evident bursts (the right picture) correspond to epidischarges and speak for the frequency and duration of epileptiform activity manifestation on the continuous record fragment.

Analysis of polygraphic channels signals combined with
EEG signals "Encephalan-CA"

Neuromonitoring and Videomonitoring allow simultaneous displaying of recorded physiological signals, indices trends, which represent the state of CNS and cardiorespiratory system in the neuromonitoring trends window.
In addition to that - compressed spectrums trends, aEEG, rhythm spectral power indices are shown in "CFM" window.
In neuromonitoring beside EEG rhythms indices and powers the following diagnostically important indices are used: median and weighted average frequency, effective bandwidth, etc.
Various indices can be shown in compressed view: ECG, EMG, pneumogramma, respiration rate, SpO2 etc. Videomonitoring, synchronized with other recorded data, gives additional diagnostically valuable information.
