Impact of high versus low fraction of inspired oxygen for anaesthetic washout and extubation on postoperative pulmonary atelectasis formation and oxygenation: a randomised controlled trial.
British journal of anaesthesia·August 1, 2026·PMID 42297665
Why it mattersAvoiding pure oxygen during emergence is a simple, low-cost strategy that may reduce atelectasis and improve early postoperative oxygenation, directly relevant to anaesthesiologists managing extubation.
