Conceptually we may break this apparent paradox down into the two opposite effects that <span class="elsevierStyleItalic">V</span><span class="elsevierStyleInf">T</span> and PEEP exert on the total energy delivered to the lung&#46; This energy and the response of the lung&#39;s parenchyma to it can be expressed through the mechanical power&#46;<a class="elsevierStyleCrossRef" href="#bib0130"><span class="elsevierStyleSup">8</span></a> Consequently&#44; in contrast to the obvious reduction in mechanical power achieved by lowering <span class="elsevierStyleItalic">V</span><span class="elsevierStyleInf">T</span>&#44; a high PEEP setting will mostly be associated with an increase in delivered pulmonary energy&#46; As recently shown in an animal model&#44; VILI is directly dependent on the delivered mechanical power&#46;<a class="elsevierStyleCrossRef" href="#bib0135"><span class="elsevierStyleSup">9</span></a> Interestingly&#44; the sensitivity analysis performed by Alapont and colleagues does indicate exactly towards this relationship&#46; Studies in which a high PEEP setting induced a higher mechanical power relative to the control group were associated with a disappearing protective effect of high PEEP&#46;</p><p id="par0025" class="elsevierStylePara elsevierViewall">The high collinearity between the mechanical power and the driving pressure shown by the sensitivity analyses of Alapont et al&#46; illustrates that the main mediator between PEEP increase and mechanical power reduction is a decreasing respiratory system elastance&#46; In other words&#44; only when an increase in PEEP leads to an effective distension of alveoli does it reduce the applied mechanical power&#46; However&#44; as Gattinoni et al&#46; showed in their landmark paper&#44; lung recruitability is highly heterogeneous&#44; and less than 40&#37; of patients seem to actively recruit a significant proportion of lung tissue during a recruitment manoeuvre&#46;<a class="elsevierStyleCrossRef" href="#bib0140"><span class="elsevierStyleSup">10</span></a> Most strikingly&#44; the authors observed that up to 24&#37; of the total lung tissue cannot be recruited at end-inspiratory plateau airway pressures of 45<span class="elsevierStyleHsp" style=""></span>cmH<span class="elsevierStyleInf">2</span>O&#46;<a class="elsevierStyleCrossRef" href="#bib0140"><span class="elsevierStyleSup">10</span></a> Hence&#44; one can speculate that more than half of the patients included in PEEP trials did not experience any alveolar recruitment and in the worst-case scenario experienced alveolar overdistension due to excessive PEEP settings&#46; This possibly induced VILI&#44; increasing mortality in the intervention group and drastically reducing statistical power&#46; Ideally&#44; we should fine tune <span class="elsevierStyleItalic">V</span><span class="elsevierStyleInf">T</span> according to elastance&#44; and PEEP according to lung recruitability&#46;</p><p id="par0030" class="elsevierStylePara elsevierViewall">But how do we recognize recruitable patients&#63; Performing two CT studies at different PEEP levels&#44; might be a very elegant option and the current gold standard&#44;<a class="elsevierStyleCrossRef" href="#bib0140"><span class="elsevierStyleSup">10</span></a> but is impractical at the bedside&#46; On the other hand&#44; recruitment assessment methods based on lung mechanics are generally limited in discerning between actual atelectatic tissue recruitment and overdistension of the baby lung&#46; The recently proposed recruitment-to-inflation ratio might provide guidance in balancing the risk of atelectrauma against the risk of overdistension during recruitment&#46;<a class="elsevierStyleCrossRef" href="#bib0145"><span class="elsevierStyleSup">11</span></a> Another emergent technique&#44; thoracic electric impedance tomography&#44; can enable to discern alveolar recruitment from overdistension in a more visual approach&#44; whilst concomitantly allowing assessment of regional pulmonary perfusion&#46;<a class="elsevierStyleCrossRefs" href="#bib0150"><span class="elsevierStyleSup">12&#44;13</span></a></p><p id="par0035" class="elsevierStylePara elsevierViewall">In a further sensitivity analysis&#44;

Conceptually we may break this apparent paradox down into the two opposite effects that <span class="elsevierStyleItalic">V</span><span class="elsevierStyleInf">T</span> and PEEP exert on the total energy delivered to the lung&#46; This energy and the response of the lung&#39;s parenchyma to it can be expressed through the mechanical power&#46;<a class="elsevierStyleCrossRef" href="#bib0130"><span class="elsevierStyleSup">8</span></a> Consequently&#44; in contrast to the obvious reduction in mechanical power achieved by lowering <span class="elsevierStyleItalic">V</span><span class="elsevierStyleInf">T</span>&#44; a high PEEP setting will mostly be associated with an increase in delivered pulmonary energy&#46; As recently shown in an animal model&#44; VILI is directly dependent on the delivered mechanical power&#46;<a class="elsevierStyleCrossRef" href="#bib0135"><span class="elsevierStyleSup">9</span></a> Interestingly&#44; the sensitivity analysis performed by Alapont and colleagues does indicate exactly towards this relationship&#46; Studies in which a high PEEP setting induced a higher mechanical power relative to the control group were associated with a disappearing protective effect of high PEEP&#46;</p><p id="par0025" class="elsevierStylePara elsevierViewall">The high collinearity between the mechanical power and the driving pressure shown by the sensitivity analyses of Alapont et al&#46; illustrates that the main mediator between PEEP increase and mechanical power reduction is a decreasing respiratory system elastance&#46; In other words&#44; only when an increase in PEEP leads to an effective distension of alveoli does it reduce the applied mechanical power&#46; However&#44; as Gattinoni et al&#46; showed in their landmark paper&#44; lung recruitability is highly heterogeneous&#44; and less than 40&#37; of patients seem to actively recruit a significant proportion of lung tissue during a recruitment manoeuvre&#46;<a class="elsevierStyleCrossRef" href="#bib0140"><span class="elsevierStyleSup">10</span></a> Most strikingly&#44; the authors observed that up to 24&#37; of the total lung tissue cannot be recruited at end-inspiratory plateau airway pressures of 45<span class="elsevierStyleHsp" style=""></span>cmH<span class="elsevierStyleInf">2</span>O&#46;<a class="elsevierStyleCrossRef" href="#bib0140"><span class="elsevierStyleSup">10</span></a> Hence&#44; one can speculate that more than half of the patients included in PEEP trials did not experience any alveolar recruitment and in the worst-case scenario experienced alveolar overdistension due to excessive PEEP settings&#46; This possibly induced VILI&#44; increasing mortality in the intervention group and drastically reducing statistical power&#46; Ideally&#44; we should fine tune <span class="elsevierStyleItalic">V</span><span class="elsevierStyleInf">T</span> according to elastance&#44; and PEEP according to lung recruitability&#46;</p><p id="par0030" class="elsevierStylePara elsevierViewall">But how do we recognize recruitable patients&#63; Performing two CT studies at different PEEP levels&#44; might be a very elegant option and the current gold standard&#44;<a class="elsevierStyleCrossRef" href="#bib0140"><span class="elsevierStyleSup">10</span></a> but is impractical at the bedside&#46; On the other hand&#44; recruitment assessment methods based on lung mechanics are generally limited in discerning between actual atelectatic tissue recruitment and overdistension of the baby lung&#46; The recently proposed recruitment-to-inflation ratio might provide guidance in balancing the risk of atelectrauma against the risk of overdistension during recruitment&#46;<a class="elsevierStyleCrossRef" href="#bib0145"><span class="elsevierStyleSup">11</span></a> Another emergent technique&#44; thoracic electric impedance tomography&#44; can enable to discern alveolar recruitment from overdistension in a more visual approach&#44; whilst concomitantly allowing assessment of regional pulmonary perfusion&#46;<a class="elsevierStyleCrossRefs" href="#bib0150"><span class="elsevierStyleSup">12&#44;13</span></a></p><p id="par0035" class="elsevierStylePara elsevierViewall">In a further sensitivity analysis&#44;
