What SpO2 target should be maintained during the non-diagnostic 12-lead ACS protocol?

• A. SpO2 > 98%
• B. SpO2 > 90%
• C. SpO2 > 92%
• D. SpO2 > 94%

Answer: (D)

Maintaining adequate oxygenation is crucial in acute coronary syndromes because enough oxygen delivery to the heart muscle helps limit ongoing ischemia and tissue damage. The non-diagnostic 12-lead ACS protocol sets a target to keep SpO2 just above the 94% mark. This level provides reliable oxygen delivery to cardiac tissue without exposing the patient to unnecessary high concentrations of oxygen, which can have drawbacks like oxygen toxicity or vasoconstriction in some patients. In practice, you’d monitor SpO2 continuously and administer supplemental oxygen if it falls below 94% or if the patient shows signs of respiratory distress or hypoxemia. If SpO2 is already above 94%, you avoid overtreatment and let the patient remain on the minimum oxygen to sustain that level. So, the best target is to keep SpO2 greater than 94% to balance adequate oxygenation with minimizing potential oxygen-related risks.
