Study hypothesis
In the acute respiratory distress syndrome (ARDS), the right level of positive end-expiratory pressure (PEEP) may decrease ventilator-induced lung injury by opening the lung and keeping it open. We evaluated whether setting the PEEP using decremental PEEP titration after alveolar recruitment manoeuvre (ARM) affects the clinical outcome in patients with ARDS.
Ethics approval
The study protocol was approved by the Institutional Board of the Ethics Committee of Asan Medical Center on the 14th August 2006 (ref: 2006-0286)

Condition
Acute respiratory distress syndrome (ARDS)
Intervention
Control group:
The FiO2-PEEP strategy has been used in previous ARDS Network studies. PEEP and FiO2 were set according to the table of lower PEEP/higher FiO2 combinations, with the goal of obtaining a lower PEEP level compatible with an oxygenation target.
Decremental PEEP titration group:
The alveolar recruitment manoeuvre (ARM) was performed immediately after enrolment in the study and was applied once a day in the morning for 1 week. After ARM, the decrease in PEEP was continued until a decrease of greater than 2% of the saturation from the previous SaO2 and drop of static compliance was identified (decremental PEEP titration).
Total duration of treatment: 1 week
Total duration of follow-up: from enrolment to leaving the hospital
