The Effects of Induction and Treatment of Intracranial Hypertension on Cerebral Autoregulation: An Experimental Study

Figure 4

CBFV and CVRi in the mild and severe ICH groups during the experiment; CBFV (p<0.002 for the comparison with ICH and p=0.04 for the comparison with saline solution) and CVRi (#p<0.02 for differences between the groups, p<0.02 for differences between the assessments in the same group, p=0.001 for differences between assessments 1 and 3, and §p=0.04 for differences between assessments 1 and 2). CBFV (cerebral blood flow velocity), CVRi (Cerebrovascular resistance index), and ICH (intracranial hypertension); 1 (basal), 2 (balloon inflation), 3 (saline solution infusion), and 4 (balloon deflation).
