The pressure-volume loop (PV loop) obtained from intratracheal pressure measurement in a pilot animal. In the left graph, ventilation was performed without positive end-expiratory pressure (PEEP) and a peak pressure (Ppeak) of 25 cm H2O, showing a sigmoid shape of the PV loop. After compliance-guided pressure adjustment PEEP was set to 4 cm H2O and Ppeak to 18 cm H2O, resulting in an almost linear relation between pressure and volume (right graph)
