Arterial oxygenation during desflurane-remifentanil vs. propofol-remifentanil anesthesia for one-lung ventilation. Data points are mean; error bars are SD. PaO₂ during OLV was lower in the desflurane group than the propofol group. During desflurane anesthesia, PaO₂ was significantly lower at 15, 30, and 45 min of OLV compared to the TLV state. PaO₂, arterial partial pressure of oxygen; TLV, two-lung ventilation; OLV, one-lung ventilation; OLV15, 15 min of OLV; OLV30, 30 min of OLV; OLV45, 45 min of OLV; OLV60, 60 min of OLV. * p <0.01 between the two groups during OLV period (linear mixed model). # Adjusted p <0.01 when compared to the TLV state in the desflurane group (linear mixed model with Bonferroni’s correction)
