<unk>  <unk> , originally known as adult<unk><unk>  syndrome (to contrast with neonatal<unk><unk>  syndrome) is a serious and potentially life-threatening inflammatory lung condition that develops rapidly (usually within 24 to 48 hours) in the setting of sepsis, toxic exposures, adverse drug reactions, trauma, or other critical illnesses.<unk>  is characterized by inflammation of the lung parenchyma resulting in increased permeability of the alveolar-capillary membrane, non-cardiogenic pulmonary edema, impaired gas exchange, and decreased lung compliance.
The vast majority of patients with<unk>  are managed in an intensive care unit (ICU), where many will require mechanical ventilation at some point during the course of their illness and recovery.<unk>  may be categorized as mild, moderate, or severe based on the degree to which oxygenation is impaired; however, all levels of severity carry a high mortality rate if appropriate measures to improve oxygenation and minimize the risk of further lung injury are not taken.
