Individual Pdi changes from the values during SBwith the two settings. The dashed and continued lines include the areasof theoretical physiologic target for Pdi (ie, a Pdireduction > 40% and < 90% of SB) for U and PHY, respectively.ΔPdi = change in Pdi.

Individual changes from the SB values in PEEPi,dynwith U setting (horizontal axis) and with PHY setting (vertical axis).The dashed and continued lines define the limits of the theoreticalphysiologic target for PEEPi,dyn (ie, a reduction>50% of SB). ΔPEEPi,dyn = change in PEEPi,dyn.
