SOMNOscreen® HD – In-Lab Polysomnography


  • The SOMNOscreen HD - SOMNOmedics most powerful & advanced PSG system.
    The SOMNOscreen HD - SOMNOmedics most powerful & advanced PSG system.


A third smaller than the SOMNOscreen Plus, the new power-house SOMNOscreen® HD offers excellent signal quality of up to 4 kHz sampling rate per channel.

The high-resolution touchscreen allows a simple and intuitive operation.  In addition, the signal – and impedance – can be seen directly on the display at the patient’s bedside.

True Wireless Technology

Real time wireless data transmission. Wireless sensor enabled for patient comfort and mobility



The future is here – our most powerful and flexible sleep diagnostic system. The SOMNOscreen HD™ is a new generation of PSG with 55 channels (10 internal, 28 external, 17 EXG via the headbox) which can be upgraded to 70 channels, they are recorded at a resolution of up to 4 kHz per channel. Excellent signal quality goes without saying. The SOMNOscreen HD™ offers the maximum flexibility in sleep diagnostics in a in-lab setting. Whether 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 intelligent connect, the new montage free sensor recognition, you can connect any sensor to any slot and also change it during the measurement. If an installation on the PC has been selected before the cable is connected, the device will indicate any missing sensors. Incorrect measurements due to forgotten or incorrectly connected sensors are thus excluded. Even without assembly, the measurements can now be started directly on the device.

Thanks to the built-in data transmitter, the SOMNOscreen HD™ allows the full mobility of the patient – making the process of a PSG more comfortable for the patient.

In addition we have a full suit of stationary video options as well as other sensors and head boxes that will exceed your expectations.

Intelligent Connect™

The new Intelligent ConnectTM technology simplifies your day-to-day work in the sleep lab by automatically recognizing which sensor has been attached.

This allows the plug-in slots for the sensors to be freely selectable and sensors can even be changed or added during the measurement.  Faulty measurements, due to incorrectly attached sensors, are now a thing of the past.  If a montage is selected on the PC before the sensors are attached to the patient, the device will show an optical signal that a sensor may be missing.

Even without a pre-set montage, the sensor measurement can be started directly from the SOMNOscreen HDTM– simply plug in the desired sensor and begin the measurement.

Docking station for simplified handling

The docking station is used to charge the SOMNOscreen® HD Li-Ion battery and to install regular, free of charge firmware updates. This means your SOMNOscreen® HD is always up to date.

A virtual docking station also appears on your PC and shows the actual status of the device.

In addition to the telemetric data transfer in real time, the measurement data is stored on an internal memory card and can be transferred to a PC via the docking station at the end of the diagnosis. This system insures no measurements are ever lost.
