Podcast 570: Oh no no no to O2

Contributor: Aaron Lessen, MD

Educational Pearls:

• Supplemental oxygen is not a completely benign intervention.
• A recent meta-analysis found that O2 saturations above 96% while on supplemental O2 were associated with worse outcomes.
• Only start a patient on supplemental oxygen if absolutely necessary and aim for a goal of no higher than 96%
