To the Editor: The ARDS Definition Task Force1 presented a consensus draft definition developed by a panel of experts. They proposed 3 categories of ARDS based on degree of hypoxemia and, using a large database (4457 patients with 1256 deaths), reported increasing severity of ARDS to be associated with increased mortality and duration of mechanical ventilation. The Berlin Definition also predicted mortality marginally better than its predecessor, the American-European Consensus Conference (AECC) definition.
