9 August 2013	Amended	Acknowledgement section updated.
10 July 2013	New search has been performed	This review is an update of a previous Cochrane systematic review of the same title (Davies 2004) that included only one study. The literature search for this current version was extended from May 2004 to November 2012, with preservation of the original criteria for study inclusion and review objectives. The abstract, background, plain language summary, methods, results and discussion sections were rewritten to take account of relevant new information on acute lung injury and partial liquid ventilation and current guidance for the completion of Cochrane reviews (Higgins 2011). Risk of bias assessment with tables and figures was included. One new eligible study was identified and included (Kacmarek 2006), yielding a total of two eligible studies. Pooled estimates of effect of partial liquid ventilation on mortality, days free of mechanical ventilation at 28 days and adverse events were calculated.
10 July 2013	New citation required and conclusions have changed	This update was conducted by four new team members (IMG, AS, NDF, RP) working together with one of the original review authors (MWD). The findings of this updated review differed slightly from those of the original review (Davies 2004) in that previously no evidence was found to support or refute the role of partial liquid ventilation in adults with ALI/ARDS; new evidence suggests that it is not superior to conventional mechanical ventilation and may be associated with a higher incidence of adverse events.
2 August 2008	Amended	Converted to new review format.
