Fig. 4From: Effects of positive end-expiratory pressure on regional cerebral oxygen saturation in elderly patients undergoing thoracic surgery during one-lung ventilation: a randomized crossover-controlled trialEffects of PEEP on hemodynamics during thoracoscopic lobectomy. (A) HR, heart rate; (B) MAP, mean arterial pressure; (C) CI, cardiac index; (D) SVV, stroke volume variability. OLV, one-lung ventilation; OLV(0), OLV ventilation with 0 cmH2O PEEP; OLV(5), OLV ventilation with 5 cmH2O PEEP; OLV(10), OLV ventilation with 10 cmH2O PEEPBack to article page
