Things We Do For No Reason (TWDFNR)
Supplemental oxygen for normoxemic patients!
- Multiple studies have shown no benefit and potentially harm when administering oxygen routinely to patients whose SpO2 is >94-96% or in those with 88-92% but underlying risk of respiratory failure (eg COPD patients)
- Do NOT give supplemental oxygen to acute MI patients unless SpO2 < 90%
- Some conditions DO necessitate hyperoxemia (pneumothorax, carbon monoxide poisoning, air embolism, sickle cell crisis, cluster headache). Give O2 even if SpO2 is 100%
