He is intubated without medications in the field, and on presentation, the Glasgow Coma Scale (GCS) score is 4. CT scan of the neck does not reveal bony injury to the cervical spine. A fiberoptic intracranial pressure (ICP) device is placed, and ICP, cerebral perfusion pressure (CPP), and brain tissue oxygen tension (Pbto2) are monitored. On hospital day 5, the GCS is 5, ICP, 18 mm Hg; CPP, 70 mmHg; and Pbto2 in the right frontal lobe near a contusion, 24 mm Hg. His cardiopulmonary status is stable. A rigid cervical collar is in place, and he is maintained on CMV mode ventilation at a set rate of 14 × 550 cc (actual RR is 21), Fio2, 0.35; and PEEP, 5.
