Fig. 2.
Bar graph showing the proportion of patients with diffuse alveolar damage (DAD) according to characteristics of the patients and criteria for severity of acute respiratory distress syndrome (ARDS). After multivariate analysis, the four variables independently associated with DAD (indicated by black bars) were duration of evolution of ARDS (≥3 days), severity of hypoxemia, increased dynamic driving pressure, and radiologic severity with diffuse opacities involving the four quadrants. C RS Respiratory system compliance, PaO 2 /FiO 2 Ratio of partial pressure of arterial oxygen to fraction of inspired oxygen, PEEP Positive end-expiratory pressure, VE CORR Corrected expired volume per minute
