Brief Summary
After severe traumatic brain injury, adequate blood flow to the brain is essential for recovery. This depends on arterial blood pressure, yet intensive care units apply fixed targets to all patients - treating every brain and patient the same. This study aims to change that. With new technology, 'optimal' blood pressure can be determined for each individual brain and treatment can be tailored accordingly. This personalized approach to neurocritical care has never been tested in a randomized controlled study before. If effective in showing reduced brain damage biomarkers, it will fundamentally transform brain injury treatment and dramatically improve recovery outcomes for patients worldwide.

Study Arms (2)
CPPopt treatment
EXPERIMENTALThe CPPopt treatment group will receive management according to the Brain Trauma Foundation (BTF) guidelines, except for the targeted cerebral perfusion pressure. Here, the calculated "optimal cerebral perfusion pressure (CPPopt)" will be targeted, with updated CPPopt targets every 4 hours.
Control group
NO INTERVENTIONThe intervention group will receive standard brain trauma management according to the Brain Trauma Foundation (BTF) guidelines, including the standard cerebral perfusion pressure target of 60-70 mmHg.
Interventions
The intervention group will receive CPPopt guided management with updated CPPopt targets every 4 hours. All other parameters will be handled according to Brain Trauma Foundation (BTF) guidelines.

- Start randomization within 24 hrs after ICU admission.
You may not qualify if:
- Known pregnancy
