Attended Polysomnography

Ready-made solution for your PSG lab

For more than a quarter of a century, Neurosoft has been designing and producing various equipment for electrodiagnostics and neurophysiology. Advanced noise reduction technologies implemented in our systems ensure high-quality of the recorded signal making our products a popular choice among healthcare professionals worldwide.

Today, we offer our Neuron-Spectrum-65/PSG system — a ready-made solution for your PSG lab. The system is intended for long-term synchronous PSG, video and audio data recording as well as for analysis of sleep, cardiorispiratory events and limb movements.

Full-featured PSG recorder of expert class, Neuron-Spectrum-65/PSG allows performing any PSG study according to the latest international requirements. Routine PSG, multiple latency sleep test, maintenance of wakefulness test are possible with that multitask device and simple thanks to the automatic calculation of the parameters necessary for diagnosis.

Full range of PSG channels in compliance with AASM* recommendations

The system is provided with the full range of channels required to perform PSG studies.

Channels for sleep staging

• up to 32 EEG channels
• 2 EOG channels
• 3 EMG channels

Channels for analysis of sleep-related respiratory events

Channels to connect:

• oronasal thermal airflow sensor
• nasal pressure airflow sensor (cannula)
• thorax respiratory effort sensor
• abdominal respiratory effort sensor
• snoring sensor
• body position sensor

Built-in channels:

SpO2 and PPG (photoplethysmography)

• ECG
• 8 DC channels for the most demanding PSG studies

Channels for limb movement recording

• 2 EMG channels

Connection to patient unit

During the in-lab PSG study, the sensors can be connected to the recorder through the portable patient unit. This allows a patient to disconnect quickly from the recorder (for example in case of bathroom needs) and then connect the sensors back to resume the recording.

Synchronous video monitoring

According to AASM, video monitoring synchronized with PSG data recording is recommended during the routine PSG testing. The video image helps accurately determine sleep-related disorders and obtain a more complete clinical picture. Neuron-Spectrum-65/PSG supports synchronous video recording from up to 3 cameras simultaneously. HD network cameras with IR illumination, day/night mode, built-in microphone, and remote control using the software ensure maximum convenience for the medical personnel.

Sleep staging and analysis of respiratory events

Neuron-Spectrum-65/PSG is supplied with advanced software that ensures automatic sleep staging, arranges sleep stage duration markers, calculates apnea/hypopnea, snoring, desaturation, and heart rate variability indices as well as determines body position independently or considering sleep stage analysis data.

Identifying the exact causes of sleep disturbances helps to select an effective treatment and prevent disease progression. Ensured by Neuron-Spectrum-65/PSG, multichannel EEG monitoring performed simultaneously with PSG study facilitates detecting epileptiform activity which often occurs in patients during sleep.

Advanced analysis tools to speed up PSG data interpretation

PSG studies last for 7-8 hours that is why it is difficult to view and analyze the whole record manually. The advanced tools implemented in Neuron-Spectrum.NET/PSG module are particularly designed to speed up PSG data interpretation:

• automatic and manual sleep staging, hypnogram creation, automatic calculation of hypnogram parameters, creation of stage distribution histograms;
• automatic search and classification of apnea/hypopnea, desaturation, snoring, hypoventilation, limb movement and periodic limb movement events, creation of HR, body position, SpO2, ETCO2, and PPT trends.
• automatic generation of the detailed report including graphical data.

PAP titration under PSG control

Today PAP therapy is the main treatment for patients with moderate and severe obstructive sleep apnea (OSA). According to the international recommendations, CPAP/BiPAP therapy titration should be done under medical personnel supervision and within PSG study when treating OSA patients with significant comorbid medical conditions (chronic heart insufficiency, chronic obstructive pulmonary disease, central sleep apnea, or hypoventilation) or when PAP therapy effect is poor.

To transfer PAP titration data, an additional unit (PSG module) should be connected to DC channel inputs of the system. PAP pressure, airflow, leakage, and some other parameters depending on the unit type will be displayed on the screen during PSG testing. The software will automatically detect respiratory events, desaturation, and calculate PSG indices (including apnea-hypopnea index) in accordance with PAP pressure.

PSG sensors and units of third party manufacturers (for example, ETCO2 monitors) can be connected to the system.
