TLV: two-lung ventilation; OLV: one-lung ventilation; PaO2: arterial oxygen tension; PaCO2: arterial carbon dioxide tension; SaO2: arterial oxygen saturation; Ppeak: peak inspiratory pressure; Pmean: mean inspiratory pressure; Pplateau: plateau inspiratory pressure. Data are expressed as mean (SD). denotes statistical insignificance.
