Somnotouch device

Manufactured by SOMNOmedics

Sourced in Germany

The SOMNOtouch device is a portable sleep monitoring system designed for ambulatory sleep studies. It is a compact and lightweight device that records various physiological signals during sleep, including respiratory signals, oxygen saturation, heart rate, and body position. The SOMNOtouch device is intended for use in sleep laboratories, hospitals, or in the patient's home environment to assist healthcare professionals in the diagnosis and management of sleep disorders.

, and did not smoke. PSG was acquired using the SOMNOtouch device (SOMNOmedics GmbH, Randersacker, Germany). Sleep scoring was performed with the validated Z3Score algorithm [31 (link)] and visually checked by trained technicians who were blinded to the Oura ring records. Wake, REM sleep, N1, N2, and N3 sleep were calculated based on 30-s epochs according to the standard criteria of the AASM. More details on the protocol for this study can be found in References [31 (link),32 (link)]. The Institutional Review Board of the National University of Singapore approved the study, which was in accordance with the principles in the Declaration of Helsinki. Informed written consent was obtained from participants and their legal guardians.

Polysomnography Protocol for Sleep Analysis

Cited 1 time

Check if the same lab product or an alternative is used in the 5 most similar protocols

Polysomnography (PSG) was performed using the SOMNOtouch device (SOMNOmedics GmbH, Randersacker, Germany). Electroencephalography was recorded from two main channels (C3 and C4 in the international 10–20 system of electrode placement) referenced to the contralateral mastoids. The common ground and reference electrode were placed at Fpz and Cz, respectively. Electrooculography (EOG; right and left outer canthi) and submental electromyography (EMG) were also recorded for sleep stage classification. EEG signals were sampled at 256 Hz and impedance was kept at less than 5KΩ for EEG and below 10KΩ for EOG and EMG channels.
Data was autoscored with the updated version of Z3Score algorithm (

), which has been previously validated and shown to be on par with expert scorers;25 (link) along with the FASST EEG toolbox (

http://www.montefiore.ulg.ac.be/~phillips/FASST.html

), and visually inspected by trained technicians who were blinded to the Oura ring and actigraphic records. Scoring of the sleep was performed based on the American Academy of Sleep Medicine Manual (AASM). WASO, REM sleep, N1, N2 and N3 were calculated based on 30-second epochs according to the AASM manual criteria.26

Comprehensive Assessment of Sleep-disordered Breathing

Check if the same lab product or an alternative is used in the 5 most similar protocols

For all children, sleep-disordered breathing was assessed using the SOMNOtouch device (SOMNOmedics, Germany) comprising: chest and abdominal respiratory inductance plethysmography; pulse oximetry (Bluepoint) yielding saturations (SpO2), plethysmography and pulse rate; nasal pressure flow with integral snore sensor; body position sensor; and actimetry. In addition, for the clinical cohort routine contemporaneous pulse oximetry (Masimo Inc., USA) and transcutaneous carbon dioxide (Sen Tec, Switzerland) monitoring was undertaken and a subgroup also had video monitoring. For study failures, families were given the opportunity to repeat the CRPG.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
