Brain Function Monitoring
A More Complete Picture Starts with More Complete Data
Brain Function Monitoring helps clinicians monitor the state of the brain under anaesthesia with bilateral data acquisition and processing of electroencephalogram (EEG) signals.

Why Monitor the Brain During Anaesthesia?
The brain is one of the most important organs in the body. By delivering greater insights into changes in brain function under anaesthesia, SedLine is designed to help monitor it before, during, and after surgery.
Deliver Balanced Anaesthesia
Titrating to the individual patient’s needs may help reduce oversedation,1 which has been linked to poor outcomes2
-
Clinical Evidence
Clinical benefit of processed electroencephalography (pEEG)
Patients may experience:
- Less burst suppression1
- Less over-sedation1
- Enhanced recovery and more rapid ventilation weaning3
Clinicians and hospitals indicate they benefit when technology impacts:
- Reduced length of stay (LOS)3
- Reduced cost per patient3
-
Clinical Evidence
EEG Patterns Associated with PACU Delirium2
“Conclusions: Specific EEG patterns were associated with PACU delirium. These findings provide valuable information regarding how the brain reacts to surgery and anaesthesia that may lead to strategies to predict PACU delirium and identify key areas of investigation for its prevention.”2
"...reasons why monitoring processed EEG may be of value: prevent awareness, save money by reducing anaesthetic cost, prevent excessively deep and unnecessarily deep anaesthesia..."

- 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
The Power of the Density Spectral Array (DSA)
SedLine offers the flexibility of choosing to display either an enhanced Multitaper Density Spectral Array (DSA) or a standard Hanning DSA.
- This provides the ability to see the symmetry of left and right sides of the brain.
- Clearly indicates incidence of burst suppression/isoelectric activity as a black line with blue tip.
- Spectral edge frequency represents where 95% of the brain power lies.
Understand the DSA
The DSA represents the power of the EEG on both sides of the brain, alongside other patient information provided by SedLine sensors. Watch the video to learn more.
Improved Depth of Sedation Monitoring with Patient State Index (PSi)
SedLine features an enhanced signal processing engine providing a better, more accurate Patient State Index (PSi), a processed EEG parameter related to the effect of anaesthetic agents. Learn how we’ve advanced this technology.

Enhanced Features
Parallel Signal Processing Engines
EMG is a common confounding factor that can interfere with EEG signals used in brain function monitoring.4 SedLine uses parallel signal processing engines to extract a clearer EEG signal for computing PSi.
-
Enhanced Features
Adaptive Signal Processing
Power across all frequency bands decreases with age.5 When computing PSi, SedLine uses adaptive signal processing with band-independent features to search for EEG features across many frequency bands.
