Advanced Monitoring · available in beta
Teach the signal behind the number.
NAP brings the raw trace, processed index, signal quality, muscle activity and suppression into one coherent teaching view—while making their limitations part of the lesson.
Interactive example · driven by NAP's processed-EEG core
A stable anaesthetic
A stable anaesthetic. A steady trace, a settled index and a low suppression ratio stay consistent.
A coherent general-anaesthetic picture: the raw trace, the processed index and the suppression ratio are consistent with one another. The 40–60 band shown here is a common reference, not a universal safe range — read the number alongside the trace and the clinical context.

What learners can see
These are related educational outputs generated together from one signal — not independent decorations, and no single one is a diagnosis.
- Raw EEG-like trace
- A generated frontal EEG waveform, drawn on an explicit microvolt scale.
- Processed index
- A vendor-neutral 0–100 index derived from the same signal — not a copy of any proprietary algorithm.
- Signal quality
- How trustworthy the current signal is; a poor signal changes what the monitor is willing to show.
- Simulated EMG
- A muscle-activity / high-frequency contribution that can influence the processed display.
- Suppression ratio
- The proportion of recent time the EEG spent suppressed, measured from the trace itself.
- SEF95 & a short trend
- Spectral edge frequency and a brief local trend of the displayed values.
- Density spectral array (DSA)
- A compressed colour heat-strip of the recent spectrum on a fixed scale — a generic depth/suppression view, never a proprietary signature, and it never back-fills history.
Four teaching moments
Each maps to a scene you can select in the interactive example above.
- 01
A stable anaesthetic
Introduce the relationship between the trace, the index and a common reference band — without calling the band universally safe.
- 02
Muscle activity confounds the picture
Show how EMG can influence the processed display, and why a number is read with context rather than alone.
- 03
Burst suppression
Show activity alternating with suppression and a rising suppression ratio — without implying one universal cause.
- 04
Poor signal or artefact
Demonstrate that bad contact or interference can make outputs unavailable or unreliable, rather than producing false certainty.
Built for teaching, not brand imitation.
The interface deliberately uses generic names and one coherent single-index model. Real depth monitors differ in their algorithms, parameters, electrode arrangements and response time — so NAP does not present vendor logos, enclosure designs, branded layouts or trademarked product names as selectable skins. What you teach here is how to read a processed-EEG picture, not how to operate one company's box.
Use it in a NAP session
- 1
Start a normal controller session.
- 2
Open the EEG tab and tap Enable processed EEG.
- 3
Choose Linked behaviour, a teaching preset, or a deliberate Manual state.
- 4
Present the processed-EEG surface while learners and read-only observers follow the same room.
Full step-by-step operation, including presets, signal conditions and advisories, is in the processed-EEG guide.
What NAP models—and what it does not.
What it models
- A shared model that coordinates the generated signal, its spectral content, suppression, signal conditions and display smoothing.
- Linked mode keeps those outputs coherent; manual mode lets an instructor construct a deliberate teaching contradiction.
- Device-authority rules: an untrustworthy signal freezes or invalidates the index instead of inventing a low value.
What it is not
- Not a reproduction of a proprietary clinical algorithm.
- Not a diagnostic or treatment device.
- Not proof of awareness, unconsciousness or anaesthetic adequacy.
- Not yet a multi-vendor device-familiarisation suite.
- Adult-modelled: in a paediatric room the adult model runs at paediatric rates and context — an informed instructor choice, not validated for paediatric patients (instructor-held caveat, not shown to learners).
