To the Editor In a large observational study of the incidence of acute respiratory distress syndrome (ARDS),1 the diagnosis was made in the analysis phase by a computer algorithm using raw data collected for each component of the Berlin Definition2 for all study patients with hypoxemia who were breathing with the aid of a ventilator. The authors concluded that ARDS is clinically underrecognized because the computer algorithm diagnosed more patients with ARDS than did clinicians.
