Recommendation:We suggest using PEEP within the range of plateau pressures less than or equal to 30cmH2O, without compromising hemodynamics (Grade 2B, strength of recommendation “weak recommendation” / Quality of evidence ”moderate”). We also suggest using higher PEEP levels in patients with moderate to severe ARDS (Grade 2B,Strength of recommendation “weak recommendation” / Quality of evidence “moderate”).

●Supplementary statements: Increasing PEEP levels may result in high plateau pressures, hypotension or a decrease in tidal volume. Close monitoring of hemodynamics and other parameters is necessary when high PEEP levels are used.
