Brief Summary:
Many patients with Acute Respiratory Distress Syndrome or ARDS need breathing support that is provided by a machine called a ventilator or respirator. The purpose of this study is to find out if a new method of setting the ventilator for patients with severe ARDS is better than the standard, commonly used way of setting the ventilator.
Detailed Description:
The ARDSnet protocol is the current, standard of care for ARDS. Mechanical ventilation is managed using low tidal volumes, relatively high respiratory rates, with oxygenation managed according to PEEP and FIO2 relationships as defined in a table. This study compares the ARDSnet protocol with an open lung approach to mechanical ventilation. The open lung approach uses a technique to recruit collapsed lung areas and then uses the lowest PEEP level that prevents recollapse of recruited lung units. The best PEEP level is determined by a decremental PEEP trial involving a series of pressure measurements taken after the recruitment maneuver. Both the ARDSnet protocol and the open lung approach require low tidal volumes and plateau pressures.
Evidence suggests that using a mechanical ventilation strategy of recruitment maneuvers (to open the collapsed lung) followed by high PEEP (to prevent collapse of the opened lung) with control of transpulmonary pressure through lower plateau pressures would maximize homogeneity within the lung and as such, minimize shearing forces in the lung parenchyma, thus improving ventilation and outcome in mechanically ventilated ARDS patients.
