Outcomes
Primary Outcomes
To assess the feasibility of the neuromonitoring system and the accuracy of the measurement values.
Time Frame: Day 28 after removal of medical device
Feasibility: User acceptance: For NeMo Probes in comparison to conventional probes for intracranial pressure (ICP-) monitoring; for NeMo Patch in comparison to patches for electroencephalography (EEG) monitoring. Detailled evaluation of user acceptance: * Incidence of concerns of users in relation to the installation, function and removal of the NeMo System (= NeMo Probe, NeMo Patch, NeMo Control Unit and NeMo Software pre-installed on a Medical PC) * User-friendliness with a 3-graded scale (equal, better, worse) compared to conventional devices Accuracy of measurements: -Patients: Results from repeated measurements of mean transit time of ICG (mttICG), cerebral blood flow (CBF) and cerebral blood volume (CBV) Safety parameters: Incidence of complications (infections, brain tissue damage, haemorrhage) compared to historical series (patches for EEG and for BIS measurements; conventional probes for ICP monitoring)
Secondary Outcomes
- To demonstrate the ability of the neuromonitoring system to detect secondary ischemic events in patients with severe subarachnoid haemorrhage (SAH) or severe traumatic brain injury (TBI).(Day 28 after removal of medical device)
