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

Patients admitted to the ICU with acute hypoxemic respiratory failure often receive supplemental oxygen with a high FIO2, which results in a high PaO2 and may be associated with increased mortality. Guidelines give no recommended oxygenation targets for adults in the ICU owing to sparse evidence.
