Our SOMNOwatch Plus encases a digital triaxial accelerometer, ambient light sensor and event marker. Combined with other modules and sensors, the SOMNOwatch Plus can becomes one of the smallest somnographs or respiratory screeners. We can also offer longterm blood pressure recordering, longterm EEG recording (via a single sensor or a headbox) or even long term core temprature rescrording. Almost anything is possible – allowing you to gather specific data for your research.
With programable software allowing extensive customisation
Body Position/Movement (seperate acc for 3 axis), Ambient light, patient marker with acoustic tone
Allowing up to 25 day study duration (depending on number of sensors attached)
BP, Resp, 6 channel EEG, long term ear temp and much much more
Over the complete measurement day by day – double plot for improved circadian analysis
The SOMNOwatch™ plus is a powerful, miniaturised, multi channel recorder which is as comfortable and user-friendly as a watch.
As any multi-channel system, the SOMNOwatch™ plus can replace several common devices while providing excellent signal quality.
The high frequency acquisition of movement data enables the SOMNOwatch™ Plus to make a very accurate frequency analysis using FFT. The recording of tremor intensity and tremor frequency can be achieved over a long period of time. This parameter can be used for the medical diagnosis and treatment of Parkinson’s disease.
Applied to the ankle, the SOMNOwatch™ Plus can continuously record Leg Movement for up to 5 nights. It can differentiate between the standing and lying position by using the integrated position sensor. With adjustable parameters, the software automatically recognizes PLM movement patterns and evaluates the PLM index. For RLS-rating (Restless Leg Syndrome) the Motor activity is quantified.
For an extended diagnosis the correlation of PLMs and Cortical Micro Arousals can be detected by using the EEG Derivation (optional).
For the detection of PLM on both legs, an external movement sensor can be fixed to the second leg, and work simultaneously with the SOMNOwatch™ Plus.
The SOMNOwatch™ Plus is validated for the detection of periodic leg movements*.

SOMNOwatch™ plus can store the raw data from a single channel ECG for up to 250 hours. The correlation between Heart Rate, its Rhythm, Actigraphy and Body Position can give very interesting information for the diagnosis of cardiovascular disease and help in patients rehabilitation.

How does it work?
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.
