In 2017, the neonatal acute respiratory distress syndrome(ARDS) Consortium Working Group has proposed diagnostic criteria for neonatal ARDS. The study consists of a prospective, multicentre, web-based,cohort study in China in which neonates who fulfil the new criteria definition are enrolled in order to: describe the epidemiology, clinical course, and prognosis of neonates affected by neonatal ARDS; identify a list of risk factors for neonatal ARDS, as it exists for adults and older children with ARDS; and guide future studies.
