Effect of PEEP on rSO2 and PaO2 in elderly patients during thoracoscopic lobectomy. (A.) (B.)There were significant differences among TLV and three PEEP levels of OLV both in rSO2 and PaO2. * OLV(0) vs. OLV(10): p = 0.008. ** OLV(0) vs. OLV(5): p = 0.005;*** OLV(0) vs. OLV(10): p = 0.001; (C.) (D.) In the column chart, rectangles depict the mean differences, and the error bars signify the standard error. TLV, two-lung ventilation; OLV, one-lung ventilation; rSO2, regional cerebral oxygen saturation; PaO2, arterial oxygen partial pressure; OLV(0), OLV ventilation with 0 cmH2O PEEP; OLV(5), OLV ventilation with 5 cmH2O PEEP; OLV(10), OLV ventilation with 10 cmH2O PEEP
