3. Fig 2
CVP in P5 and P15 groups during the surgery. BL, baseline; BLpeep, baseline after increasing PEEP to 15 cm H2O; BLpp, baseline after the establishment of pneumoperitoneum; POpp, postoperative values, before exsufflation of pneumoperitoneum. Depending on the varying lengths of surgery, most curves have a gap in the time interval before POpp. The top black line represents IAP (16 mm Hg) and the bottom black line PEEP (5 and 15 cm H2O). Every piglet is represented by one curve.
