What is the oxygenation target you should maintain in suspected STEMI?

• A. Keep SpO2 greater than 94%
• B. Keep SpO2 greater than 88%
• C. Keep SpO2 between 90-95%
• D. SpO2 is not a consideration in STEMI

Answer: (A)

In suspected STEMI, the goal is to ensure adequate oxygen delivery to the ischemic myocardium by keeping the patient’s oxygen saturation from falling below a level that could worsen ischemia. The recommended target is to maintain SpO2 greater than 94%. This helps ensure the heart muscle receives enough oxygen during a critical event and can help limit further injury. If the saturation drops below this threshold, provide supplemental oxygen to bring it back above 94% and monitor closely to avoid letting it fall again. Keep in mind that while you want to avoid hypoxemia, you should use oxygen guided by oxygen saturation readings rather than administering it without need.
