edema (prostacyclin to improve microcirculation) , and (5) the "cerebral ischemia model" (Robertson option), which relies upon the use of jugular venous oxygen saturation (SjVO2) monitoring to avoid global cerebral ischemia. These different options are summarized in Table 5.2. Although there is not a unified approach, with the exception of the Lund therapy, the consensus appears to be CPP at >60 mmHg  and MAP at >80 mmHg. Phenylephrine and norepinephrine are the most common agents used to support blood pressure in these patients. Both agents have negligible direct effects on the cerebral vasculature. Commonly used vasoactive agents are listed in Table 5.3.
