Potential risks of hyperoxemia

Potential risks of hyperoxemia:

  1. Detrimental effects due to vasoconstriction of the vasculature
  2. Generation of reactive oxygen species which could cause:

Earlier it was common practice to give supplemental oxygen for acute coronary syndrome and after percutaneous coronary interventions. This practice has been discontinued after publication of the DETO2X-AMI trial [1] and other similar studies which showed no benefit for supplemental oxygen in those with normal oxygen saturation.
