This study's objective is to determine the safety, feasibility and efficacy of prolonged automated robotic TCD monitoring in critically ill patients with severe TBI across multiple clinical sites with varying levels of TCD availability and experience
Upon informed consent, patients will undergo daily automated robotic TCD monitoring sessions for up to 4 hours a day for a total duration of at least 3 days and up to 5 days whenever clinically feasible. TCD monitoring of bilateral middle cerebral artery cerebral blood flow velocity (MCA CBFV) will be performed using a robotic TCD system equipped with bilateral 2-MHz Doppler probes. This system allows for continuous bilateral extended duration recording of MCA CBFV, using robotically controlled TCD probes that allow automated angle correction to maintain optimal MCA insonation.

Inclusion Criteria: * Adults ≥18 * Blunt TBI with Glasgow Coma Score (GCS) ≤8 * Injury within 72 hours * Adequate TCD windows * Ability to obtain informed consent from a Legally Authorized Representative (LAR) Exclusion Criteria: * Catastrophic brain injury with grim prognosis (e.g.: GCS 3 with bilateral mid-position pupil) * C- spine fracture with evidence of spinal cord injury * Severe skull or scalp injury precluding device placement * Planned decompressive hemicraniectomy * Continuous fever for \>6 hours at the time of enrollment (despite treatment) * Lack of TCD window
