Next Generation SedLine® Brain Function Monitor
A More Complete Picture Starts with More Complete Data
Root® with Next Generation SedLine Brain Function Monitoring helps clinicians monitor the state of the brain under anaesthesia with bilateral data acquisition and processing of electroencephalogram (EEG) signals.
Next Generation SedLine Features:
- Four simultaneous channels of frontal EEG waveforms
- An enhanced Patient State Index (PSi), a processed EEG parameter related to the effect of anaesthetic agents
- Next Generation PSi offers less susceptibility to EMG interference and improved performance in low power EEG cases
- A Density Spectral Array (DSA) display, which contains left and right spectrograms representing the power of the EEG on both sides of the brain
- An optional Multitaper DSA, which may improve visibility of EEG features
Reducing Electromyography (EMG) Susceptibility
Next Generation SedLine utilises Masimo’s Parallel Signal Processing Engines to extract a clearer EEG signal and compute a processed EEG parameter (PSi) less influenced by EMG. EMG can interfere with EEG signals used in brain function monitoring. Researchers have found that EMG interference existed in up to 38% of monitored patients.1
This image captures a moment when Next Generation SedLine detects EMG in the two engines depicted.
Improved PSi Performance in Low Power EEG
Power across all frequency bands decreases with age. Low power can present a challenge for conventional brain function monitors.2 Next Generation PSi uses adaptive signal processing with band-independent features to offer improved PSi performance in cases of low power EEG.
The subjects above were administered Propofol and were in a comparable anaesthetic state.3
Next Generation PSi Searches For EEG Features Across Many Frequency Bands
Multitaper Density Spectral Array (DSA)
Next Generation SedLine offers clinicians the flexibility of choosing to display either an enhanced Multitaper Density Spectral Array (DSA) or a standard Hanning DSA. The DSA contains left and right spectrograms representing the power of the EEG on both sides of the brain.
When using a Multitaper DSA, EEG data are transformed into the frequency domain, which may provide a better display of EEG features.
Next Generation SedLine on the Root Platform
The Next Generation SedLine module easily plugs into the Root patient monitoring platform via Masimo Open Connect® (MOC-9®) ports. Root’s customisable, easily-interpretable display offers multiple views of brain monitoring information, expanding visibility in the operating theater and intensive care unit.
Next Generation SedLine can be used simultaneously with O3® Regional Oximetry on the Root platform for a more complete picture of the brain.
SedLine EEG Sensor
- Four active EEG leads collect data in the frontal lobe
