Fig. 2

Representative volume-based capnograms during incremental PEEP with 1 cmH2O (ac) and 0.2 cmH2O (d, e) steps to determine the etCO2D PEEPi. The previously determined occlusion method yielded a PEEP value of 5.4 cmH2O. a A full normal capnogram is represented. b When the expiratory pressure in the ventilator is increased from 5 to 6 cmH2O, the end-tidal dilution becomes visually evident. c When the end-expiratory pressure is increased further to 7 cmH2O, the capnogram becomes diluted at an earlier point during expiration
