What is the recommended oxygen saturation target during post-resuscitation care?

The recommended oxygen saturation target during post-resuscitation care is set at 94-98%. This range is based on evidence suggesting that maintaining oxygen saturation within these levels optimizes oxygen delivery to tissues while minimizing the risk of hyperoxia, which can lead to oxidative stress and potentially detrimental effects on cells.

Studies have shown that excessively high oxygen levels (above 98%) can be harmful, especially after resuscitation, as they can lead to oxidative injury. Conversely, targeting a saturation lower than 94% could indicate inadequate oxygenation and increase the risk of tissue hypoxia. Therefore, aiming for the range of 94-98% strikes a balance, ensuring that patients receive sufficient oxygen and reducing the risk of complications associated with both hypoxia and hyperoxia. This approach aligns with guidelines from resuscitation councils and best practices in managing patients post-cardiac arrest.
