Changes of PaO2, PaCO2, Ppeak, Pplat. A group: DLBT group; B group: BB group. T0: immediately after anesthesia; T1: at 20 minutes of OLV; T2: at 60 minutes of OLV; T3: 10 minutes after recovery from TLV. ?P < .05, compared with T0 in group A; #P < .05, compared with T0 in group B; ∗P < .05, compared with group A. BB = bronchial blockers, DLBT = double-lumen bronchial tubes, OLV = one-lung ventilation, PaCO2 = arterial partial pressure of carbon dioxide, PaO2 = arterial partial pressure of oxygen, Ppeak = airway peak pressure, Pplat = airway platform pressure, TLV = two-lung ventilation.
