Objectives: Hysteresis of the respiratory system pressure-volume curve is related to alveolar
surface forces, lung stress relaxation, and tidal reexpansion/collapse. Hysteresis has been …

Objective 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. Design Prospective …

Objectives: The impact of recruitment maneuvers on gas exchange, hemodynamics, alveolar
recruitment, and hyperinflation is highly variable among patients with acute respiratory …

Background Lung strain, defined as the ratio between end-inspiratory volume and functional
residual capacity, is a marker of the mechanical load during ventilation. However, changes …

Rationale: The assessment of lung recruitability in patients with acute respiratory distress
syndrome (ARDS) may be important for planning recruitment maneuvers and setting positive …

Selecting the ideal combination of positive end-expiratory pressure (PEEP) and tidal volume
has remained an unsettled issue in ventilatory management of acute respiratory distress …

Objective: The objective of this study was to assess the effects of positive endexpiratory
pressure on recruitment, cyclic recruitment and derecruitment and strain in patients with …

BACKGROUND: In acute lung injury, ventilation avoiding tidal hyperinflation and tidal
recruitment has been proposed to prevent ventilator-associated lung injury. Information …

Mechanical ventilation may promote overdistension-induced pulmonary lesions in patients
with acute respiratory distress syndrome (ARDS). The static pressure-volume (PV) curve of …

In normal subjects breathing spontaneously, complicance has been shown to be influenced
by the lung volume from which deflation started. We wondered whether this would also be …
