Lung Open Ventilation to Decrease Mortality in the Acute Respiratory Distress Syndrome
A Randomized Trial of a Lung-Open Ventilation Strategy in Acute Lung Injury
A multinational, randomized trial comparing two lung protecting strategies of respiratory life support among critically ill patients with severe lung injury.
To compare an innovative Lung Open Ventilation strategy with a proven low tidal volume strategy, hypothesizing that the Lung Open Ventilation strategy may reduce mortality, other organ dysfunction, and the duration of mechanical ventilation, intensive care, and hospital stay.
