Table 1 Scoring system of amplitude integrated electroencephalography (aEEG)
Score | Curve variability | SWC | Lower boundary values | Narrow-band width and lower boundary voltage |
|---|---|---|---|---|
0 | No variation curve | None | Seriously inhibited (< 3 μV) | Amplitude suppression: low amplitude (≤15 μV) and low voltage (5 μV) |
1 | Some curve, no sinusoidal ariation | Starting occurrence period | Some inhibition (3~ 5 μV) | Immaturity amplitude: high amplitude (> 20 μV) or medium amplitude (15~ 20 μV) and low voltage (5 μV) |
2 | Sinusoidal ariation | No clear | No inhibition (> 5 μV) | Immaturity amplitude: high amplitude (> 20 μV) and high voltage (> 5 μV) |
3 | Clear period, but suspension | Gradually mature amplitude: medium amplitude (15~ 20 μV) and high voltage (> 5 μV) | ||
4 | Clear period, no suspension | Mature amplitude: low amplitude (< 15 μV) and high voltage (> 5 μV) | ||
5 | Rule and mature period |
