• Portable electroencephalograph for mobile application

EEG-recorder is used for short-term and continuous EEG studies – in a hospital room or at patient's home, including EEG-video monitoring for the differential diagnosis of epilepsy.

Portable electroencephalograph-recorder with SW EEG-studies "Encephalan-EEGR" allows safely and efficiently carrying out both short-term and long-term studies with topographic mapping and the use of modern methods of quantitative EEG data processing such as spectral, auto and cross-correlation analysis, the coherence function, mapping, identification of artifacts and seizure activity.

Automatic forming of EEG description and classification. Editor of conclusions, electronic Cardfile and print manager help to save and document the results of studies.

• Autonomous EEG-recorder (Holter EEG)

Continuous autonomous EEG-study is effective for:

• Evaluation of psychogenic disorders of not defined genesis, which are manifested under conditions of natural environment and behavior.

• Detection of pathological manifestations, such as paroxysmal epileptic states, transient ischemic attacks, and others.

• Differential diagnosis of epilepsy, types of seizure and syndromes, especially in irregular and illdefined paroxysm.
• Control in drugs administration.

Continuous record of electroencephalogram (over 48 hours) onto the memory card integrated into the patient transceiver-recorder ABP-26, and a special set of electrodes "Encephalan-ES" provide comfortable carrying out of autonomous EEG studies (Holter EEG) in natural patient environment, both in a hospital ward or at home, during active wakefulness and sleep.

During autonomous study, the device provides a unique opportunity for periodic functional tests in the telemetric mode required to induce controlled pathological manifestations.

The main modification of electroencephalograph-recorder "Encephalan-EEGR-19/26" in combination with "maximum" suite of software "Encephalan-PSG" and necessary sensors forms polysomnograph with telemetric and autonomous (Holter-type studies) record for diagnostics of sleep disorder (insomnia, hypersomnia, parasomnia, narcolepsy), breathing disorders (sleep apnea syndrome, alveolar hypoventilation, snoring) and heart rate disorders, ischemic heart disease, neurological and psychosomatic disorders (epilepsy, restless legs syndrome).

"Encephalan-PSG" software

Reports, which contain data in tables and graphical form, are formed according to common international standards (AASM). Report can contain fragments of raw signals, selected phenomena, video data and parameters trends.

Software "Encephalan-EEGR" is used for Full-valid EEG analysis.

Polysomnographs can be supplemented with autonomous, mobile or stationary kit for EEG-PSG videomonitoring

Portability of patient transceiver-recorder ABP-26, backup of all recorded data on the internal memory card and wireless data transmission to the computer provide high noise immunity from the effects of different equipment in the emergency room and intensive care units.

Neuromonitoring with optional software "Encephalan-NM" is meant for long-term multiparametric monitoring for continuous analysis of EEG dynamics and other physiological signals in order to control the current state, for timely diagnosis of central nervous, cardiovascular and respiratory systems disorders, assessment of the anaesthetic depth and decision making on the necessary therapeutic interventions, etc.

Cerebral functions monitoring with optional software "Encephalan-CFM" is used to assess the functional state of the brain and neurological status in patients with ischemic stroke and unconscious post-comatose states, to detect paroxysmal brain activity, its severity and frequency, and to control the dynamics of a patient state in therapeutic intervention and the states of asphyxia, low cerebral perfusion and brain damages in children (mainly newborns) as well as in adults.

"Encephalan-CFM" and "Encephalan-NM" can be used separately as optional software to the main software "Encephalan-EEGR", but the most informative and effective monitoring of parameters is provided in at their simultaneous operation.

The main features of the electroencephalograph, main modification, are:

• 12 or 20 EEG derivations providing greater possibilities for biofeedback and neurofeedback procedures by EEG and DC-potentials using quantitative methods of analysis (qEEG, aEEG).
