Figure 6

Linear regression lines show that the hemoglobin volume (HVx) and cerebral oximetry (COx) indices were consistent with preserved autoregulation during induced hypertension. (A) Post-arrest, normothermic piglets (n = 8), and (B) post-arrest, hypothermic piglets (n = 8) displayed negative HVx with rising cerebral perfusion pressure (CPP), indicating intact cerebrovascular reactivity. (C) Post-arrest, normothermic piglets (n = 8), and (D) post-arrest, hypothermic (n = 8) piglets also had overall low COx values, indicating functional autoregulation. Data are shown with 95% confidence intervals.
