SOMNOscreen™ plus - For the Sleep Laboratory


  • The SOMNOscreen Plus - the original portable sleep laboratory PSG device.
    The compact PSG is comfortable to wear on the body.


The established and proven SOMNOscreen plus – stationary polysomnography. Over 5,000 devices sold and permanently refined for 15 years: The SOMNOscreen™ plus stands for proven and reliable quality in polysomnography. In addition to the standard features, the SOMNOscreen ™ plus can be flexibly and modularly upgraded with a variety of additional sensors and up to 32 EEG channels. We find the right solution for every requirement in your sleep laboratory.

Shortest EEG Electrode with Continuous Impedance Check

Lower noise, higher signal quality & with confirmation of proper electrode hook-up during and after study

Small Compact robust Design

One device fits all making it easier to fit to all shapes and sizes of patients

Cuffless Continuous Blood Pressure Measurement

A new era in measuring blood pressure in a sleep laboratory – without disturbing sleep

Wireless Data Transfer

In real time – for patient comfort and mobility


SOMNOscreen plus – stationary polysomnography is a compact In-Lab PSG system with 33 channels that is upgradable to 58 channels. It offers the maximum flexibility in diagnostics. Whether you are analyzing the measurement according to the AASM standard or configurations for specific studies, it is always you who decides what you would like to measure and with which configuration you would like to start with. The SOMNOscreen™ plus can be upgraded at any time and offers in one device the possibility of performing polygraphy screenings, outpatient and stationary PSGs up to the neurological application with complete EEG 32 derivation – all this with the highest patient comfort.

Thanks to the built-in data transmitter, the SOMNOscreen™ plus always works wirelessly – allowing your patients to move around freely. In addition, the measurement is saved on the memory card of the SOMNOscreen ™ plus – no data is lost!

We also have a full suit of stationary video options that will ensure you can offer reliable, industry leading sleep studies night after night.

Cuff-Less Continuous Blood Pressure Measurement (optional)

  • Systolic / diastolic blood pressure (in mmHg), beat-to-beat, records all maxima / minima
  • Recording of nocturnal blood pressure fluctuations *
  • Recording of the rise in baseline blood pressure during REM *
  • No annoying inflation of the cuff during the night, no disturbance of the patient
  • Minimized deviation due to body position change (minimization of the hydrostatic effect)
  • Suitable for all sizes, no different cuff sizes or cleaning necessary
  • Correlation of blood pressure with sleep-related events
SOMNOmedics uses an innovative patented algorithm to measure blood pressure via the Pulse Transit Time (PTT). The PTT is the time required for the pulse wave to propagate along the vessel wall between two defined points. In the case of the SOMNOtouch RESP – From the left ventricle of the heart (defined by the ´R´peak of the ECG) – to the detection of the pulse wave at the finger tip (detected by the plethysmograph).

Taking a one point calibration at the beginning of the sleep study allows us to `set` the software‘s algorithm – and measure blood pressure continuously throughout the measurement. Because every single pulse wave is detected, a continuous “Beat-to-Beat”- recording and analysis is possible. Reduce artifacts and increase the number of reliable data points – all in a continuous, non-invasive and non-reactive way.


Additional Options

  • Sidestream Capnometer
  • Transcutanious CO2
  • Pneumotachograph for flow determination under PAP therapy
  • Intercostal EMG for for better differentiation between central and obstructive sleep apnea
  • Core Body Temperature
  • High frequency analysis of snore

The above is a small selection of our most popular options. We have a wide range of other items and accessories – please contact us should you require anything that is not listed here.



Our devices are only as good as the reports that are produced. That is why our sleep diagnostic reporting tool is powerful and configurable. To see a sample report please click below where you will be able to see full report.
