The VT 4 ml/kg group
the dependent lung will be ventilated with a TV of 4 mL/kg (predicted body weight), respectively, whereas FiO2, I: E ratio, PEEP, frequency, Ppk, and a FGF will be maintained as during two-lung ventilation (TLV) and the lumen of the nondependent lung will be left open to air. Dependent lung recruitment maneuvers will be repeated at 30-minute intervals by raising the inspiratory pressure up to 35 cmH2O for 10 seconds.
The VT 6 ml/kg group
the dependent lung will be ventilated with a TV of 6 mL/kg (predicted body weight), respectively, whereas FiO2, I: E ratio, PEEP, frequency, Ppk, and a FGF will be maintained as during two-lung ventilation (TLV) and the lumen of the nondependent lung will be left open to air. Dependent lung recruitment maneuvers will be repeated at 30-minute intervals by raising the inspiratory pressure up to 35 cmH2O for 10 seconds.
The VT 8 ml/kg group
the dependent lung will be ventilated with a TV of 8 mL/kg (predicted body weight), respectively, whereas FiO2, I: E ratio, PEEP, frequency, Ppk, and a FGF will be maintained as during two-lung ventilation (TLV) and the lumen of the nondependent lung will be left open to air. Dependent lung recruitment maneuvers will be repeated at 30-minute intervals by raising the inspiratory pressure up to 35 cmH2O for 10 seconds.
