Fig. 2

End-expiratory pressure–volume curves for atelectatic (solid line) and overdistended lung volume (dashed line) are depicted for healthy (a) and injured lungs (b). Fractional lung volumes are given as the difference between 5 and 27 cmH2O of positive end-expiratory pressure (PEEP). Median pressure–volume curves were derived, and lower and upper inflection points were calculated using the Venegas equation [30]. For atelectatic lung, lower and upper inflection points and for overdistended lung, lower inflection points are provided
