Baseline difference in the perfusion of two lungs is the cause of intra-operative shunt during one-lung ventilation (OLV). This study aimed to test the hypothesis that the gradient of end-tidal carbon dioxide (EtCO 2 ) between two lungs in lateral position (D-EtCO 2lateral ) would predict the quantity of shunt and hence the drop in the oxygenation during OLV.
