SOMNOscreen™ plus – Home & Ambulatory PSG


  • The SOMNOscreen Plus - the original portable PSG device.
    The SOMNOscreen Plus - the original portable PSG device.


SOMNOscreen Plus – portable polysomnography – The original & proven PSG device that has been constantly refined over the past 15 years. Field proven, robust and durable – why choose anything else?

In addition to PSG diagnosis our Home Sleep Camera is a innovative solution for synchronous video in an ambulatory setting – especially where reimbursement demands video e.g. for adult or paediatric ambulatory polysomnography in an environment where you need synchronous video, but can’t have online recording due to network restrictions.


Colour & Mechanical Coded

For easier sensor handling

Up to 58 Channels with excellent Signal Quality

For all PG, PSG & PSG + EEG Application with unique active sensors

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, allowing ambulatory & stationary applications

Cuffless Continuous Blood Pressure Measurement

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

Online Remote Signal Check

Allows signal quality and impedance check at patient’s bedside in an ambulatory setting


The SOMNOscreen™ plus is a compact PSG system with 33 channels that is upgradable to 58 channels. It offers the maximum flexibility in diagnostics. Whether according to the standard of Rechtschaffen & Kales, 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.

Thanks to the built-in data transmitter, the SOMNOscreen™ plus always works wirelessly – allowing for remote signal check – giving you peace of mind whilst doing ambulatory/home sleep test.

Adding video to this powerful device gives you new opportunities to offer HST to an exceptionally high standard.

Optional Video

The Mobile camera includes:

  • Tripod, case
  • Power supply
  • Built in Infrared-illumination
  • Video resolution of 800 x 600 pixel, in the H.264 format
  • Audio
  • Record up to 90 hours of video.
  • It’s small in size (137 x 124 x 71 mm) and light at only 460 g.
  • The accuracy of the synchronization between recorded data and video is ± 1 second

In the software the following can be achieved:

  • Synchronous play to physiological data.
  • Selectable speed (stepwise between 0.25 and 100x) with loop option.
  • 150 MB/h video size

Ambulatory Video Work Flow
  1. Initialise a recording with SOMNOscreen and the Home Sleep Camera.
    Both devices need to be connected to the same PC: The SOMNOscreen via its docking cable, and the Home Sleep Camera via LAN cable.
  2. Give SOMNOscreen Plus and the Home Sleep Camera to the patient.
  3. Patient set up camera at home in the evening: Assembles the tripod, connects to a power supply. The video recording will start automatically
  4. Patient packs up the video and tripod and gives the whole package back to the physician
  5. Transfer recording including video. Both devices need to be connected to the same PC: The SOMNOscreen Plus via its docking cable, and the Home Sleep Camera via LAN cable.
Optional Online signal check on a tablet or PC

Transfers the measured data to your tablet, PC or smart phone for instant signal check – right at the patient’s bedside or mobile as a screenshot. Transfer times and periods can be programmed individually.


Data analysis and report

  • Automatic & manual sleep staging
  • Synchronized video playback
  • Automatic event detection and immediate report printout
  • Additional respiratory analysis by effort-based phase angle analysis
  • Manual editing
  • Automatic detection of artifacts
  • Standard or user defined reports

Please visit our dedicated software page for more information.


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.



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.
