Current stance on routine oxygen therapy for all ACS patients?

Oxygen acts as a drug and should be used only when needed in ACS. Giving oxygen to every patient with an acute coronary syndrome does not improve outcomes and can even cause harm in those who are not hypoxic. When SpO2 falls below about 90–92% or the patient is clearly hypoxic, administer oxygen and titrate to keep saturation around 90–92%. Routine high-flow oxygen in patients who are adequately oxygenated is not recommended because hyperoxia can worsen myocardial ischemia through coronary vasoconstriction and increased oxidative stress. In patients with ACS who are normoxic, no extra oxygen is needed beyond standard monitoring and treatment.
