After ROSC, which statement best captures the oxygenation strategy?

• A. Always deliver 100% oxygen indefinitely
• B. Saturation target 88-92%
• C. Do not use supplemental oxygen
• D. Target approximately 94-98%

Answer: (D)

After ROSC, oxygenation should be carefully balanced to ensure adequate oxygen delivery without causing oxygen toxicity. Excessive oxygen can worsen injury through oxidative stress and impaired microcirculation, while too little oxygen risks tissue hypoxia. The preferred target is to maintain oxygen saturation in the mid-to-high 90s, typically about 94-98%. You adjust FiO2 based on pulse oximetry (and ABG as needed) to stay in that range; if SpO2 rises above 98%, reduce FiO2, and if it falls below ~94%, increase FiO2. The 88-92% range is used only in specific conditions like COPD to avoid CO2 retention, not as a general post-arrest target. Delivering 100% oxygen indefinitely is not recommended because of hyperoxia risks. Therefore, aiming for around 94-98% best captures the oxygenation strategy after ROSC.
