Multimodal biosignal parameter observation

What is g.FEATUREmonitor?

The g.FEATUREmonitor is a high performance biosignal recording system with the ability of online parameter extraction and comprehensive visualization of the results. Video data can be stored together with the biosignals and the computed parameters.

The system is designed for long-term investigation and clinical research. It also allows to store the biosignal parameters without the raw data to save disk space.

The standard device is equipped with a g.USBamp (16 channels, 24 bit, 4 separated ground potentials, DC-coupled wide range inputs, sampling with up to 38,4 kHz). This amplifier is a CE and FDA approved medical device and can be used for EEG, ECoG, EMG, EOG, ECG and many other types of recordings.

The following parameter can be computed online:

CFM

Cerebral Function Monitor (amplitude integrated EEG (aEEG) with automatic classification of DLVP, DHVP, CVP, ISO, BSP, UDP)

The g.FEATUREmonitor is availabe as a convenient trolley system (with integrated isolation transformer, color printer and CCD camera on a swiveling holder) or as a portable notebook system with an optional battery supply.

 

 

Especially for neonatology g.FEATUREmonitor is the first system that provides investigations of brain activity (CFM, CSA) and heart activity (HR, HRV) together on a fully equipped video-EEG system.

The recorded parameter patterns can be viewed offline togehter with the synchronized raw signals and video data for precise and detailed interpretation.

The g.FEATUREmonitor automatic CFM pattern classification is used to monitor the ongoing brain function of premature infants in the neonatal intensive care unit. The system assigns class lables to data segments (e.g. epochs of 10 mintues). The following classes are used as default. DLVP (discontinous low voltage pattern), DHVP (discontinuous high voltage pattern), CVP (continuous voltage pattern), ISO (iso-electric pattern), BSP (burst supression pattern), and UDP (undefined pattern). Other classes can be defined according to special applications. In addition to the online classification there is also an offline CFM-toolbox as a part of g.BSanalyze (g.tec's biosignal analysis software package) availabe.


Highlights
     
continuous and non-invasive cerebral and autonomous nervous system observation
long term observation from hours to days combined with observing of sudden changes within seconds
fully equipped EEG and ECG recording system
tool to perform neurophysiological studies in high-risk patients/neonates
 comprehensive output can be also interpreted at the bedside
   
   

Valid for Research applications
Easy usage and interpretation of results
In many cases the time compressed output can be interpreted in a simple and effective manner even by non-experienced observers. g.FEATUREmonitor can be integrated very well into the ICU, interfering neither with the daily routines of patients care nor with therapeutic and diagnostic interventions.

High quality EEG and ECG recorder / video EEG
g.FEATUREmonitor is also a fully equipped digital EEG and ECG recorder. This allows to investigate the raw-data on-line on the monitor and to display trends, reactivity and sleep cycles. In this way seizure activity can be identified which is not obvious in the aEEG. Additionally, statistical analysis can be made from the recorded data.

Multi-channel recordings
g.FEATUREmonitor is equipped with multiple EEG channels to investigate EEG asymmetries between right and left hemispheres, to detect focal seizures and to act as fully equipped EEG recording system.

Comprehensive graphical report
The physiological parameters are presented to the expert in a comprehensive manner. This makes the interpretation easier and allows to present several hours of the recording on a single sheet of paper. The report can be printed or sent to other experts via internet.

User-extensions
Due to its flexible design g.FEATUREmonitor can record other biosignals like EMG, EOG, respiration and many more. Parameter extraction algorithms can also be added to the system.
