Position of esophagus between open and closed lung units in adult respiratory distress syndrome. Position of esophagus in relation to the interface between open and closed lung units in a patient with early-stage adult respiratory distress syndrome. Regional pressure recorded within the esophagus (Pes) and along the sagittal and coronal planes that intersect it may be representative of pressures relevant to the stress-focused and relatively unstable units at the aerated and airless interface. VILI, ventilator-induced lung injury.
