title: [Pressure-volume curves in acute pulmonary injury].
abstract: Static pressure-volume curves of the respiratory system from patients with acute lung injury have been extensively studied as a marker of aeration and recruitment phenomena and as a tool to set mechanical ventilation. The inflection points of these curves allow to identify both the pressures in which recruitment starts and finishes and those in which derecruitment starts. However, setting the ventilatory parameters based on these curves has some problems, derived from the fact that setting PEEP and plateau pressures in these patients must balance between the benefits of recruitment and the risks of overstretching caused by high pressures. It remains to be determined if new data derived from these curves are useful to optimize ventilatory settings or to predict the response of a patient to a change in the ventilatory settings.
