ReviewTherapy for late-phase acute respiratory distress syndrome.
Prolonged hypoxemic respiratory failure and evidence of lung organization and fibrosis are features of an ARDS subgroup that is variably identified as "late," "persistent," or "fibroproliferative" ARDS. Early reports suggested that patients with late ARDS had a high mortality unless treated with corticosteroids. ⋯ Additionally, there is no compelling evidence that persistent ARDS confers a higher mortality than that of ALI/ARDS. Observational and interventional studies are needed to increase understanding of the incidence, best management, and outcomes of patients with persistent ARDS.

ReviewNew modalities of mechanical ventilation: high-frequency oscillatory ventilation and airway pressure release ventilation.
Management of acute lung injury (ALI) and the acute respiratory distress syndrome (ARDS) is largely supportive, with the use of mechanical ventilation being a central feature. Recent advances in the understanding of ALI/ARDS and mechanical ventilation have revealed that lung-protective ventilation strategies may attenuate ventilator-associated lung injury and improve patient morbidity/mortality. High-frequency oscillatory ventilation and airway pressure release ventilation are two novel alternative modes of ventilation that theoretically fulfill the principles of lung protection and may offer an advantage over conventional ventilation for ALI/ARDS.
