El Tahan MR, et al. – Researchers presumed that the use of low tidal volumes (V_T) during one–lung ventilation (OLV) provides adequate gas exchange and improves postoperative outcome. In this current study, it was shown that use of low V_T during OLV attenuated airway pressure but worsened gas exchange. This strategy appeared to offer lung–protection, without apparently influencing postoperative pulmonary complications (PPCs) and hospital stay (HLOS).
