PbtO2
Partial pressure of oxygen in brain tissue
Abbreviation: PbtO2
The oxygen content of the white matter of the brain. It is determined by inserting a small monitor directly into the brain parenchyma. Normal values are > 20 mm Hg.
Low brain tissue oxygen tension (PbtO2), or brain hypoxia, is an independent predictor of poor outcome 1)
