Effects of 30% vs. 60% inspired oxygen fraction during mechanical ventilation on postoperative atelectasis: a randomised controlled trial

A study analyzed the impact of different oxygen levels (30% vs. 60%) during mechanical ventilation on postoperative atelectasis. The research included 120 patients, split evenly between the two oxygen groups. Results showed no significant difference in atelectasis volume between the groups. Other factors like aeration regions and oxygenation also remained comparable.


Conclusions: Using 30% oxygen during ventilation doesn't reduce postoperative atelectasis compared to 60%.
