intrinsic positive end-expiratory pressure elevated positive end-expiratory pressure and dynamic pulmonary hyperinflation caused by insufficient expiratory time or a limitation on expiratory flow. It cannot be routinely measured by a ventilator's pressure monitoring system but is measurable only using an ex...
The impact of PEEP on ventilator-induced lung injury depends on the extent of dynamic strain reduction. We hypothesized that R/I may reflect the potential for lung recruitment (i.e. recruitability) and, consequently, estimate the impact of PEEP on dynamic lung strain, both assessed through ...

At the start of an experiment, the umbilical cord was clamped and the animal was ventilated with a F r o , of 1.0 using a Harvard animal ventilator in a closed system with an O,-filled spirometer and calcium carbonate for CO, absorption. After an initial equilibration period, the animal ...
In this article, the authors review the basic mechanisms of PEEP, its effect on ventilator-induced lung injury, how it should be used at the bedside, how much PEEP is required in patients with acute respiratory distress syndrome, and the current knowledge on the effects of PEEP on the ...

Thus, a positive pressure breath may overstretch one lung area while failing to open another one, compromising gas exchange and causing direct mechanical injury to the lung (so-called ventilator-induced lung injury). Both the volume and pressure settings on a ventilator have been implicated in ...

In this study, ventilator-driven alveolar lung recruitment will be performed using the incremental PEEP method with the target PEEP set at 20 cmH2O and the target Ppeak set at 40 cmH2O. Individualized PEEP will be obtained by Cstat titration in obese patients. The effect of iPEEP on perioper...
We found that expiratory flow limitation was associated with both high and complete “PEEP-absorber” behavior, but our results also suggest that setting a relatively high respiratory rate on the ventilator can prevent from observing complete “PEEP-absorption.” Therefore, a simple evaluation of the...
