  1. T0 represents pre-injury phase in which craniectomies are not formalized. PtiO2 probes were inserted after trauma, recording PtiO2values only from T1
  2. T2 and T3 italic values represent PtiO2values below the theoretical critical ischemic threshold
  3. PtiO2 at T4 bold values were significantly increased when compared with pre-transfusion times
