Administration of oxygen to ischemic patients improves medical outcomes
the verdict
CONTESTED
the evidence cuts both ways
confidence 30/100
The administration of supplemental oxygen to ischemic and critically ill patients is increasingly contested, as recent large-scale clinical trials and systematic reviews indicate that conservative oxygen targets often yield equivalent or superior outcomes compared to liberal oxygenation, which carries risks of hyperoxic injury.
