Effects of out-of-bed armchair positioning on oxygenation in spontaneously breathing ICU patients receiving respiratory support: a randomized controlled trial.
Intensive care medicine·June 1, 2026·PMID 42149248
Why it mattersOptimizing oxygenation in spontaneously breathing ICU patients is a daily clinical challenge with limited evidence on positioning strategies. This trial provides direct evidence that a simple, low-cost intervention—sitting patients out of bed in an armchair—can improve oxygenation compared to standard semi-recumbent positioning, potentially aiding weaning and recovery.
