Incidence of Acute Lung Injury in Children

Acute lung injury in children is a syndrome of rapid onset of acute respiratory failure and require admission into intensive care units (ICU) for advanced life support. There are almost no information on epidemiology of acute lung injury. Published studies do not have information for an entire year and none of them have evaluated the degree of oxygenation failure under standard ventilator settings. The investigators will perform a 1-year prospective audit of all patients admitted with acute lung injury in a network of pediatric ICUs in Spain.
