Appropriate Blood Pressure in Cerebral Aneurysm Clipping for Prevention of Delayed Ischemic Neurologic Deficits

Figure 1

The ROC curve (a) presents the optimized cutoff point of mean of the lowest point of blood pressure and end-tidal carbon dioxide, whereas the optimized cutoff point of the mean difference between the lowest point and the baselined point at initial procedure is shown as the ROC curve. (b) The recommended optimal cutoff point of each line is presented with a red dot (LP, the lowest point; Δ, mean difference; SBP, systolic blood pressure; DBP, diastolic blood pressure; MAP, mean arterial blood pressure; ETCO₂, end-tidal carbon dioxide).
