After ROSC, what oxygen saturation target is recommended to prevent hypoxemia without causing hyperoxia?

• A. 88-92%
• B. 92-96%
• C. 94-98%
• D. 100%

Answer: (C)

After ROSC, the priority is to ensure enough oxygen delivery without pushing oxygen levels too high. Hypoxemia can worsen brain and heart injury, while excessive oxygen can cause oxidative stress and vasoconstriction that may impair perfusion. Targeting a SpO2 in the mid‑90s—roughly 94-98%—provides a balance: it helps prevent hypoxemia but avoids the risks associated with hyperoxia. Adjust FiO2 to keep SpO2 within this range rather than aiming for 100%, unless there’s a specific clinical reason. This approach aligns with guidelines that advocate avoiding both hypoxemia and hyperoxia in the postarrest period.
