Zusammenfassung:[...]with OC the PbrO2 in the tissue of traumatic brain injury (TBI) patients without hypoperfusion reaches up to 123 [96–138] mmHg (supplement 2) [1]. [...]with OC in all groups of traumatic and non-traumatic brain injury patients, the PbrO2 reaches to arterial oxygen pressure (PO2) levels (i.e. 62 mmHg in hypoperfusion zones and 91 mmHg in no brain hypoperfusion zones). [...]the blood that is in said environment has to be arterial. [...]it favours to equally distribute PO2 among all cells by capillary length in homogeneous tissue.
