INTRODUCTION
Until today, ambulatory 24-hour blood pressure measurement is carried out by means of a cuff device, which inflates and measures every 15 minutes during the day and every 30 minutes during the night. At night, however, the established cuff-based instruments have various weak points, since measuring errors caused by inflation of the cuff and resulting awakening reactions can lead to misdiagnosis. Due to the discontinuous measurement, blood pressure fluctuations and spikes can not be detected, especially during REM sleep. However, more accurate findings can be made with a continuous measurement of
the systolic and diastolic blood pressure, which accurately maps all the minima and maxima in the blood pressure curve.
The SOMNOtouch™ NIBP represents the latest generation of ambulatory blood pressure recording at SOMNOmedics. It measures blood pressure continuously, beat-to-beat, based on the pulse transit time (PTT), which is determined by a 3-lead ECG and the photoplethymogram from the finger clip. Our unique method is patented and clinically validated multiple times.

SOMNOtouch™NIBP in practice
The course of nocturnal blood pressure has a high diagnostic value.Continuous Blood Pressure Measurement with every heart beat
Continuous blood pressure determination without a cuff offers a multitude of advantages in nocturnal blood pressure measurements during sleep:
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 NIBP – From the left ventricle of the heart (defined by the ´R´peak of the ECG) – to 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 day and night. 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.How does it work?
In addition to the continuous, non-reactive long-term blood pressure measurement, further diagnostically relevant information are simultaneously recorded in one measurement: Due to the parallel recording, the measurement results can be correlated directly with each other, which allows a deeper insight into the nocturnal blood pressure behavior.5 Simultaneous measurements in one device
Long-term ECG
3 channel ECG
The following reports are offered as standard.
• ECG report
• Stress report based on HRV
• Export to different file formats (EDF, SCP, ASCII, etc.)
However for advanced analysis we offer a Schiller software plugin for our Domino Software (optional)
ECG Holter analysis: analysis of arrhythmias and ST-distance measurement.
Online signal check at patient´s bedside
The built in Bluetooth module makes it possible to transfers the data in real time. You can do a signal check both, on the high resolution touch display of the SOMNOtouch™ , as well as having a screenshot of the recording data sent to your tablet PC or mobile phone via e-mail. Transfer times and -periods can be programmed individually.
Intelligent Connect™
With the innovative Intelligent Connect™ Technology: Both AUX slots can be used for any sensor that fits, the devices automatically detects which sensor has been connected to it. Therefore patients can not confuse many of the sensors when they apply the device themselves; physicians on the other hand do not always have to pre-chose a montage.
