EEG-studies at the patient's whereabouts

Conducted in a wireless mode in hospital rooms, at home, in the ambulance car, under field conditions. All equipment required for studies and PC can be transported kept in one shoulder bag.

The program ensures high-quality recording of 21 EEG/EP derivations and constant potentials that characterize extra-low brain activity, and also ECG, EMG, EOG and signals from respiration recursion and body position sensors.

Effective visual analysis and quantitative methods of EEG/EP processing allow conducting rigorous and full neurophysiologic diagnostics..

Neuromonitoring and Cerebral functions monitoring

Compactness of the patient transceiver-recorders ABP-26 and ABP-10, reliable back up data storage on a Memory Card and wireless transfer of information to the PC guarantee noise immunity and effective use of the Electroencephalograph as a neuromonitor under the conditions necessary for treatment of the patient.

Native neurophysiological data, current values and trends of monitored signals are conveniently represented on ergonomic LCD which can be distanced from the recording place (up to 6 m) for the purpose of effective neuromonitoring and convenience of manipulation and staff care for the patient.

Long-term EEG-videomonitoring

The "Gold Standard" for differential diagnostic of epilepsy type is ensured by the possibilities of ambulatory long-term EEG-monitoring in patient-friendly conditions and long-term EEG recording synchronized with video picture in hospital rooms or at home.

EEG videomonitoring sets "Encephalan - video" (stationary or portable) ensure accurate synchronization of EEG, video- and audio data, cues and markers, and include tools for quick searching of epiphenomena, video or EEG-data fragments, their autoview at different speeds (speeded up, slowed-down review, page scrolling and freeze-frame) and documenting.
Special option allows making video-clip or CD/DVD disk with study data.

Safe data storage is ensured both during the study conducting and on completion of the study.

Ambulatory EEG-monitoring

There is an original technology that provides EEG-monitoring (up to 72 h record to memory card) combined with periodic functional EEG-studies (phono- and photostimulation, hyperventilation) for differential diagnostics and for pharmacotherapy control (the dynamics of threshold of readiness for convulsions).

Polysomnographic studies

Wireless device for record of respiration parameters and motion activity, wireless pulseoximeter and "Encephalan PSG" software together with autonomous patient transceiver-recorders ABP-26 or ABP-10 ensure quality carrying out of the sleep study.

The results of PSG-study are hypnogram (built in automatic mode or manually), a report on sleep statistics, sleep stages diagrams and study description with a medical comment.

Compact wireless stimulation control block ensures conducting of functional tests for phono-, photostimulation at the patient's whereabouts.

The block has autonomous battery power supply, control is performed from the doctor's PC via telemetric channel. There is embedded lightemitting diode matrix for standard photostimulation.

"Encephalan-ES" set

Original removable electrode systems (for grown-ups and children) consisted of specially designed tubular (AgCl) electrodes (Click-tube™) and of a set of fixative elastic caps (15 sizes) ensure comfortable for a patient long-term EEG-studies and high quality of signal recording.

Digital event marker

Intended for keeping patient's journal, saving time event marks and voice comments on the patient's state during long-term ambulatory EEG-monitoring. The information is transferred after a study from a marker to the doctor's PC (USB interface) and synchronized with EEG-data for further analysis.

Wireless accessoiries

Used for determination of cerebral energy exchange intensity characteristics (metabolic alterations dynamics) in the process of study, including continuous.

Synchronized record of spontaneous EEG and extra-low activity (constant potential level) is performed. Signals of extra-low activity can be displayed in the form of a random circuit of referential wiring reconstruction and topographic mapping - neuroenergymapping (NEM). Some scientists consider the NEM - method an electrophysiological analogue to the Positron emission tomography according to its medical significance.

The study of evoked potentials

The results of EP studies as addition to the EEG-results help the doctor on the bases of quantitative indices to estimate functional state of a cerebrum, localization and severity of abnormalities, also help to detect abnormality of central nonspecific and nociceptive afferentation, possible cognitive disorders, etc.

Videostimulation study of evoked potentials (Audiovisual stimulator)

To investigate perception mechanism and to detect individually important information multimodal stimuli are presented to a test person while analyzing EEG/EP.
The important peculiarity is subsensory stimuli presentation mode with specified masking stimuli that help to distract attention of a person being tested onto other images concealing the true purpose of studies and the content of subsensory stimuli used.
EEG/EP recording and all stimuli and markers are absolutely synchronized (synchronization is ensured with the help of special sensor or net-operated).

To fix reaction (pressing a button) of a person being tested to various stimuli, the Patient Button Unit is used.

3D Localization of Sources "Encephalan 3D"

Designed for detecting focal manifestations of seats of pathological cerebral activity or functional seats using special EEG and EP analysis. 3D localization is used as an additional method, especially in cases when the seat of pathological cerebral activity has no obvious morphological changes and cannot be recorded with the help of the CT and MRI.
The results of the analysis are displayed in the form of the "cloud" of distribution of equivalent dipoles on the cerebrum cutoffs, and in the form of amplitude topographic maps of initial and reconstructed EEG.

Polysomnographic studies

Polysomnographic studies are the main method for sleep disturbances diagnostics (insomnia, hypersomnia, parasomnia, narcolepsy), sleep respiratory distress (sleep apnoea syndrome, alveolar hypoventilation, snore) and concomitant cardiovascular diseases (heart rate disturbance, coronary disease), and also neurological and psychosomatic disturbances (epilepsy, restless legs syndrome, bruxism, etc.) Studies can be carried out both in autonomous (at the patient's whereabouts, with record to the flash-card, like Holter type) and in telemetric (Bluetooth) mode.

Combined signal analysis

Used for scientific research in the case when a great number of different physiological signals (e.g. all signals obtained from APB-26, APB-10, adapters connected to them, and also from wireless sensors) has to be processed.
For convenience of visual analysis of multi-type physiological signals an original method of phased cardio-cyclic presentation and stage-by-stage dynamics is used (bound to functional tests, optional record fragments, or defined time periods with specified level of time compression).
Such compressed way of presentation in single time scale obviously shows the correlation between signals that characterizes different systems of an organism.

Heart rate variability

Designed for autonomic nervous system (ANS) state assessment on basis of heart rate variability analysis.
It can be additionally used for analysis of the dynamic of the patient's state using ECG recorded in the process of long-term EEG-studies as a result of pharmacotherapy, physical and psycho-emotional stresses, and also for controlling the treatment effectiveness. It allows detecting the dysfunctions of ANS during sleep and wakefulness.
