Pressure – Volume loop (P/V curve) sketch summarizing findings of the study: Anesthetized children with ZEEP (panel a) and after setting PEEP at 5 cmH2O (panel b). PIP, PPL and Paw increased after addition of PEEP of 5 cmH2O (PIP’, PPL’,Paw’), but dP decreased (dP'). Given the same VT, CRS, represented as the angle of the diagonal line between PEEP and PPL, increased (CRS’). All of them are sign of a more efficient working pressures of the respiratory system better position in P/V curve. On (panel b) respiratory mechanics with ZEEP was added in gray tone as reference
