During respiratory or cardiac arrest, what oxygen target is recommended?

Explanation:
In arrest, the body’s ability to oxygenate and deliver oxygen to tissues is severely impaired, so the goal is to maximize the amount of oxygen carried by the blood that is circulating. Providing 100% oxygen during CPR ensures the highest arterial oxygen content is available to tissues despite the low perfusion, improving the chances of brain and heart protection during chest compressions. After return of spontaneous circulation, oxygen is then titrated to avoid hyperoxia, but during the arrest itself the priority is maintaining the maximum possible oxygen content.
