| Research Abstract |
Acute respiratory distress syndrome (ARDS) is characterized by acute pulmonary edema secondary to increased pulmonary vascular permeability. Although diagnostic criterion of ARDS reflecting the pathophysiological features of this condition has not been defined, we established a novel quantitative criterion of ARDS, using pulmonary vascular permeability combined with increased extravascular lung water content by a prospective, multi-institutional, observational study. We also demonstrated that the stages of ARDS by the Berlin definition predict increases in both the amount of extravascular lung water and the degree of pulmonary vascular permeability. The Berlin stages of disease progression are also associated with the severity of physiological derangements and damage-associated molecular patterns may be involved in the pathophysiology of ARDS.
