Masimo - Next Generation SedLine® Brain Function Monitor

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 anesthesia 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 anesthetic agents
  • 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 enhance visibility of EEG features

Improved Patient State Index (PSi)

 

Improved PSi Performace

Masimo - Improved PSi Performance Graph

Experts found an overall 17% improvement in Next Generation PSi performance.

Next Generation SedLine features an enhanced signal processing engine which provides an enhanced Patient Sate Index (PSi), a processed EEG parameter related to the effect of anesthetic agents.

EEG experts scored the improvement in PSi performance between SedLine PSi and Next Generation SedLine PSi.1

Parallel Signal Processing Engines

 

EMG is a common confounding factor that can interfere with EEG signals used in brain function monitoring.2 Next Generation SedLine utilizes Masimo’s Parallel Signal Processing Engines to extract a clearer EEG signal for computing PSi.

Adaptive Signal Processing with Band-Independent Features

 

Power across all frequency bands decreases with age.3 When computing PSi, Next Generation SedLine uses adaptive signal processing with band-independent features to search for EEG features across many frequency bands.

Multitaper Density Spectral Array (DSA)

 
Masimo - 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 customizable, easily-interpretable display offers multiple views of brain monitoring information expanding visibility in the operating room and intensive care unit.
