The incidence of ARDS varies widely, partly because studies have used different definitions of the disease. Moreover, to determine an accurate estimate of its incidence, all cases of ARDS in a given population must be found and included. Although this may be problematic, recent data are available from the United States and international studies that may clarify the true incidence of this condition.
