Fig. 1From: The effect of dexmedetomidine on cerebral perfusion and oxygenation in healthy piglets with normal and lowered blood pressure anaesthetized with propofol-remifentanil total intravenous anaesthesiaExperimental design. The experimental flow for the two groups (NBP normal blood pressure group, LBP low blood pressure group), with the median duration of each period (min–max range in brackets). Key time points are marked (arrows), and corresponding time points between groups are joined by dotted lines.
