مستخلص: To assess the hysteresis of the pressure–volume curve (PV curve) as to estimate, easily and at the bedside, the recruitability of the lung in ARDS patients. Prospective study. Twelve medico-surgical ICU beds of a general hospital. Twenty-six patients within the first 24 h from meeting ARDS criteria. A Quasi-static inflation and deflation PV curve from 0 to 40 cmH2O and a 40 cmH2O recruitment maneuver (RM) maintained for 10 s were successively done with an interval of 30 min in between. Hysteresis of the PV curve ( H PV) was calculated as the ratio of the area enclosed by the pressure volume loop divided by the predicted body weight (PBW). The volume increase during the RM ( V RM) was measured by integration of the flow required to maintain the pressure at 40 cmH2O and divided by PBW, as an estimation of the volume recruited during the RM. A positive linear correlation was found between H PV and V RM ( r = 0.81, P < 0.0001). The results suggest using the hysteresis of the PV curve to assess the recruitability of the lung.
