Figure 5

Trend plots of mean ICP/mean ICP wave amplitude of Signals 1 and 2 (PatID 1). The trend plots of mean ICP and mean ICP wave amplitude (MWA) of (a) Signal 1 and (b) Signal 2 of PatID 1 is shown [Average of mean ICP: 7.6 mmHg (Signal 1), 4.3 mmHg (Signal 2). Average of mean ICP wave amplitude: 4.1 mmHg (Signal 1), 4.0 mmHg (Signal 2)]. The vertical arrows indicate sudden changes in mean ICP without accompanying changes in MWA; mean ICP changed differently for the two signals, being more extensive for Signal 2.
