The PCV-VCV group
During the PCV period, the inspiratory pressure will be adjusted to deliver a TV of 6 mL/kg (predicted body weight) to the patient's dependent lung. During the VCV period, the patient's dependent lung will be ventilated with a TV of 6 mL/kg (PBW). 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.
