  1. MAP mean arterial pressure, ICP intracranial pressure, CPP cerebral perfusion pressure, calculated as per MAP–ICP. T0 shows only values of MAP as ICP probe was inserted after injury (T1). Patients with high ICP indicated in bold, a = CPP below 50 mmHg requiring metaraminol infusion. Venous saturation of oxygen (Sv02) expressed in %. Continuous cardiac output (CCO) expressed in liters per minute (L/min). Bold values indicate ICP higher then normal. Italic values indicate the increase in Cardiac Output after transfusion
