From: Effects of targeted mild hypercapnia versus normocapnia on cerebral oxygen saturation in patients undergoing laparoscopic hepatectomy under low central venous pressure: a prospective, randomized controlled study

Fig. 2

Changes from the Phase 1 until Phase 7. Figures 2–1 Changes in (a) left regional cerebral oxygen saturation (L-rSO2), (b) right regional cerebral oxygen saturation (R-rSO2), (c) mean arterial pressure (MAP), (d) heart rate (HR). Figure 2–2 (a) end-tidal carbon dioxide partial pressure (PetCO2), (b) central venous pressure (CVP) and (c) bispectral index score(BIS). Phase 1 = baseline before anesthesia induction; Phase 2 = post-induction; Phase 3 = post cutting the skin; Phase 4 = after the reverse Trendelenburg position; Phase 5 = parenchymal transection; Phase 6 = after parenchymal transection, fluid resuscitation; Phase 7: after endotracheal tube extubation. Groups: TN = targeted normocapnia; TMH = targeted mild hypercapnia. Data are expressed as mean ± standard deviation. *p < 0.05 compared between two groups; #P < 0.05 vs. Baseline in each group
