Figure 8

Trend plots of mean ICP/mean ICP wave amplitude of Signals 1 and 2 (PatID 4). The trend plots of mean ICP and mean ICP wave amplitude (MWA) of (a) Signal 1 and (b) Signal 2 of PatID 4 is shown [Average of mean ICP: 8.6 mmHg (Signal 1), 1.5 mmHg (Signal 2). Average of mean ICP wave amplitude: 3.3 mmHg (Signal 1), 3.2 mmHg (Signal 2)]. The vertical arrows in (a) and (b) indicate shifts in mean ICP without accompanying changes in MWA; mean ICP shifted differently for the two signals, being more extensive for Signal 1.
