When ventilating an apneic patient post-return of spontaneous circulation, which oxygen saturation target should be maintained?

• A. 100%
• B. 92% to 98%
• C. 85% to 90%
• D. 95% to 100%

Answer: (B)

Maintaining an oxygen saturation target of 92% to 98% for an apneic patient who has just regained spontaneous circulation is crucial for optimizing oxygen delivery to tissues while avoiding potential complications of hyperoxia. In the context of post-cardiac arrest care, the emphasis is on balancing sufficient oxygenation with reducing the risk of oxygen toxicity. High oxygen levels, particularly saturations approaching 100%, can be harmful, as they may lead to vasoconstriction and potential lung injury, especially in the setting of pre-existing pulmonary issues. Setting the target range at 92% to 98% ensures that the patient is receiving adequate oxygen while minimizing risks. This range allows for good tissue oxygenation and is generally well-tolerated, supporting recovery without overloading the body with oxygen, which can lead to oxidative stress.
