Figure 2

Brain tissue oxygen pressure (PtiO2) versus different cerebral perfusion pressure (CPP) thresholds. This box-and-whisker plot shows the PtiO2-CPP relationship at different CPP thresholds. Half of samples were hypoxic (PtiO2 ≤ 15 mmHg) for CPP values below 60, and were reduced to a quarter and 10% for CPP values between 60 and 70 mmHg, and above 70 mmHg, respectively (p < 0.01).
