Recommendation: We suggest prone positioning in adult patients with ARDS (especially in patients with moderate to severe respiratory dysfunction). (GRADE 2C, Strength of recommendation “weak recommendation” / Quality of evidence “low”)

●Supplementary conditions: Experienced staff are required to perform prone positioning. The effect of prone positioning may be insufficient if performed for a short time, for example, if sufficient personnel are available only for a limited period of time. Knowing the capabilities of the treating facility, especially staffing levels, is required.
