Providing supplemental oxygen in the ICU often exposes patients to a high Fio2 and a higher-than-normal Pao2, which have been associated with increased mortality and fewer ventilator-free days. Studies have suggested that establishing regimens for limiting oxygen use could improve outcomes. New research findings are summarized in a short video. https://nej.md/2PZmFNA | The New England Journal of Medicine
