    The SOMNOtouch RESP - our biggest ideas in our smallest PG device.


The SOMNOtouch™ RESP is the smallest full color touch screen Polygraphy device on the market today.

In addition to the standard signals for a screening (Flow & Snore, efforts, SpO2, pulse rate, plethysmogram, body position, CPAP/BiPAP pressure), the SOMNOtouch™ impresses with its standard integrated actigraphy sensor. On the basis of the body position and actigraphy, a detailed sleep-wake assessment can be made, so that it can be differentiated between sleep, wake and events.

The time in bed is determined by the patient via the interactive patient marker. Thanks to its color touchscreen and Intelligent Connect technology, the SOMNOtouch ™ RESP is easy and intuitive to use. Integrated sensors and the built-in Li-Ion battery keep the running costs per measurement low.

Below you will find further information as well as the technical data of the SOMNOtouch ™ RESP.


Small Compact Robust Design

Same footprint as a credit card allowing unparalleled comfort. Only 64g! Ideal for both adult & pediatric applications

Touch Screen Display

Allows PC independent set-up & signal quality check at the patient’s bedside

Low Running Costs

Reusable sensors and minimal disposables. Built in Li-Ion rechargable battery

Intelligent Connect

Automatic sensor recognition – making montages a thing of the past

Cuffless Continuous Blood Pressure Measurement

A new era in measuring blood pressure – without disturbing sleep (subject to FDA approval)



The SOMNOtouch™ RESP combines the highest comfort and the best technology in an extremely small device.  Even though it’s hardly larger than a credit card, real-time data is displayed on the high-resolution touch screen. Extremely light weight, only 64g including the battery, yet very powerful.

Miniaturized Polygraph

Integrated Sensors:

  • Pressure (Flow & Snore)
  • Effort (Thorax / Abdomen)
  • SpO2, Pulse rate
  • Body position
  • Movement (Sleep / Wake Determination)
  • CPAP/BiPAP – Pressure

Up to 16 additional channels can be connected via the two open auxiliary connectors, e.g. PLM, ECG, EEG, EOG, EMG.

Online signal check on a tablet, smartphone 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.

Docking Station for simplified handling

The docking station charges the Li-Ion battery of the SOMNOtouch ™ RESP and regularly loads free firmware updates. So your SOMNOtouch ™ RESP is always up to date.

The virtual docking station on the PC displays the current status of the device.

Intelligent Connect™

With the innovative Intelligent Connect™ technology all slots can be used for every sensor, the device automatically detects, which sensor has been connected to it. Therefore patients can not confuse any sensors when they apply the device themselves. Sleep technicians on the other hand do not have to pre-chose a montage. 

Data analysis and report

  • Computer aided event detection and immediate report printout
  • Additional respiratory analysis by effort-based phase angle analysis
  • Standard or user defined reports

Please visit our dedicated software page for more information.

Optional Sensors and Analysis

  • Simplified, ambulatory sleep scoring with combi electrode (1 EEG, 2 EOG, ambient light)
  • Sleep scoring according to AASM (4 EEG, 2 EOG, 1 EMG)
  • PLM detection
  • Blood pressure determination (via Pulse Transit Time, PTT)

Optional Continuous Blood Pressure Measurement with every heart beat

The Blood Pressure measurement function is not approved by the FDA and should only be used for research purposes.

  • Covers all max. and min. values, never miss an event (real max and min)
  • Detection of BP fluctuations during night time *
  • Detection of BP base line shift during REM stage*
  • No patient disturbance during the day or night
  • Minimized deviation caused by body position changes
  • Fits all sizes, no cuff size selection or disinfection required
  • Correlation with all sleep events

How does it work?

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.
