Fig. 2

Representation of brain tissue oxygen pressure (PbtO2) and arterial blood partial pressure of oxygen (PaO2) during hyperoxia test at FiO2 100%. Each test is represented by two points united by one straight line. Depending on regional cerebral blood flow (rCBF) points and lines are black full circles united by black lines (normal rCBF) or grey triangles united by grey dotted lines (oligemia, i.e., regional cerebral blood flow < 35 mL/100 g × min). The blue line unit means of PbtO2 and PbtO2 at FiO2 100% in the group with normal rCBF and the red line units means in the group with oligemia
