Recommendation: We suggest fluid restriction in the management of adult patients with ARDS. (GRADE 2B,Strength of recommendation “weak recommendation” / Quality of evidence ”moderate”)

●Supplementary conditions: It was considered that there is no evidence for optimal indicators or target values for fluid management, as well as methods of fluid restriction, in adult patients with ARDS. Two RCTs to evaluate indicators for fluid management comparing extravascular lung water and PAWP or CVP have been recently reported, but the mortality rate was not improved in these studies. In addition, although the duration of mechanical ventilation was shortened in one study [122], the usefulness was not particularly shown in the study [123].
