[Ventilation in ARDS: respirator, prone position, NO or artificial lung]

This review discusses the treatment of impaired gas exchange in acute respiratory distress syndrome (ARDS) using conventional ventilation, the open lung approach, prone position, nitric oxide (NO) inhalation and extracorporeal membrane oxygenation (ECMO). It is concluded that ventilation with high inspiratory pressures or volumes should be avoided, and that the open lung approach should be used as the first step. If this does not lead to satisfactory results, prone positioning is recommended, and if life-threatening hypoxemia persists, ECMO could be considered. NO inhalation is not recommended.
