Type IV-Type I sleep studies devices (according to AASM)
A portable screening respiratory system with pulse oximetry for diagnosis of obstructive sleep apnea. (Type IV AASM)Sleep signals recorder "ApnOx"
4 channels record the following parameters:
Polysomnograph for cardiorespiratory disorders analysis (Type III AASM) Psychophysiological telemetric system "Rehacor-T" with "Encephalan-PSG" software for somnological studies
- oxygen saturation
- pulse rate;
- perfusion index;
- pressure airflow;
- respiratory rate;
- respiratory amplitude;
- body position;
- body movements.
Physiological signals (7-13 channels in various combinations) are recorded by using autonomous patient transceiver-recorder ABP-4, wireless pulse oximeter module, other modules, electrodes and sensors.
"Encephalan-PSG" software ("Basic" suite) generates reports on sleep statistics based on automatically detected sleep events:
Laboratory-based or ambulatory (mobile) polysomnographic system (Type II AASM)Electroencephalograph-recorder "Encephalan-EEGR-19/26", modification "Mini"(AT-Somno, AT-Somno-Video versions) with "Encephalan-PSG" software for somnological studies
- central apnea;
- obstructive apnea;
- tachycardia and bradycardia (by ECG);
- body position;
- limbs movement;
- critical SpO2;
- body movements
- autonomous arousal.
A system with an increased number of channels (18-24), including up to 6 EEG channels, provides telemetric and autonomous record of physiological signals using autonomous patient transceiver-recorder ABP-10, wireless pulse oximeter module, other modules, electrodes and sensors. This system provides the same functionality for cardiorespiratory disorders analysis as the polysomnograph based on "Rehacor-T" (type III).
"Encephalan-PSG" software ("Maximum" suite) displays brain rhythms power indices, EOG and EMG amplitude, parameters of respiration, movements, snoring and ECG in a form of trends for quick search of EEG patterns, identification of sleep stages, as well as for manual and automatic hypnogram building, and anlysis of various sleep disorders.
"Encephalan-PSG" software provides automatic calculation of such additional sleep statistical parameters by EEG as:
Laboratory-based (stationary) polysomnographic system. (Type I AASM)Electroencephalograph-recorder "Encephalan-EEGR-19/26", main modification (AT-PSG, AT-PSG-Video, AT-PSG-Video-Poly versions) with "Encephalan-PSG" software for somnological studies
- total sleep time;
- sleep stages duration;
- sleep efficiency;
- sleep latencies and stages latencies;
- number, indices and duration of EEG arousals;
- number and duration of awakenings (WASO).
Polysomnographs of type I are characterized by an increased number of EEG channels (20 and more) to diagnose sleep related forms of epilepsy and other neurological diseases.
The polysomnographs are suitable both for stationary application in expert class sleep laboratories and for mobile application.
The sales package includes autonomous patient transceiver-recorder ABP-26, wireless pulse oximeter module, other modules, electrodes, and sensors.
Polysomnograph’s software additionally provides analysis of multichannel sleep EEG, detection of epileptic patterns and classification of spike-waves in relation to sleep structure using various methods of EEG quantitative analysis.Kits of video equipment with "Encephalan-Video" software provide visual analysis of paroxysmal activity and symptoms of sleep disorders synchronously with electrical brain activity that is crucial in differential diagnosis of epilepsy.
