Figure 1

Simultaneous 6-s time windows of Signals 1 and 2 (PatID 2). A 6-s time window of the raw signal of (a) Signal 1 and (b) Signal 2 of PatID 2, showing the cardiac-induced ICP waves. For every cardiac-induced wave the amplitude (dP) and rise time (dT) were automatically determined (c). Mean ICP, mean ICP wave amplitude (MWA) and rise time (MWRT) were determined for each 6-s time window; for the 6-s time window shown in a-b, mean ICP was 21.3 mmHg (Signal 1) and 10.9 mmHg (Signal 2), MWA was 4.1 mmHg (Signal 1) and 4.1 mmHg (Signal 2), and MWRT was 0.21 sec (Signal 1) and 0.20 sec (Signal 2).
