Dependent and non-dependent tidal volume distribution. Tidal volume distribution in the dependent and non-dependent regions are presented in relation to incremental PEEP levels. The dependent region consists of posterior and mid-posterior regions combined and non-dependent region consists of mid-anterior and anterior regions combined. During low PEEP levels the tidal volume is mainly distributed to the non-dependent region and as PEEP is gradually increased the tidal volume distribution is progressively shifted to dependent regions. During PEEP 9 cmH2O the distribution between dependent and non-dependent regions are closest to each other, representing the most homogeneous antero-posterior volume distribution. Further increasing PEEP caused an augmentation of dependent volume distribution dominance. Standard deviation is presented as error bars
