Timely administration of supplemental oxygen during cardiac arrest resuscitation efforts has been shown to significantly improve patient outcomes. Oxygenation, in conjunction with early defibrillation and cardiopulmonary resuscitation (CPR), plays a vital role in maintaining cerebral and systemic organ perfusion, thereby reducing morbidity and mortality.
Survival Outcomes With Oxygen Administration
When bystander CPR, automated external defibrillator (AED) use, and supplemental oxygen are provided in combination, survival rates to hospital discharge have been reported as high as 38%. The administration of oxygen during resuscitative efforts supports adequate arterial oxygen saturation, mitigating the risk of hypoxic-ischemic brain injury and improving the likelihood of favorable neurological outcomes.
Outcomes in the Absence of Oxygen
In contrast, the absence of supplemental oxygen correlates with significantly lower survival rates. Even when bystander CPR and defibrillation are initiated, survival may drop to approximately 9% if oxygen is not administered. This disparity underscores the critical physiological need for oxygen to support aerobic metabolism during and after resuscitation. Hypoxia remains one of the primary contributors to post-arrest neurological impairment and death.
Time-Sensitive Interventions: Oxygen and Defibrillation
Survival following cardiac arrest is time-dependent. The likelihood of survival decreases by an estimated 7–10% for every minute that defibrillation and adequate oxygenation are delayed. Early administration of high-flow oxygen, particularly in out-of-hospital settings, is strongly associated with improved clinical outcomes and is consistent with current resuscitation guidelines that emphasize the importance of optimizing oxygen delivery during cardiac arrest management.
Clinical Guidelines and Recommended Practices
Contemporary resuscitation protocols from organizations such as the American Heart Association (AHA) advocate for maintaining appropriate oxygen saturation levels in patients experiencing cardiac arrest. The use of high-flow oxygen delivery systems is recommended to ensure adequate tissue oxygenation and to minimize the risk of secondary organ injury during the post-resuscitation phase.

Conclusion
The evidence is unequivocal: the administration of supplemental oxygen during cardiac arrest significantly enhances survival rates and neurological outcomes. Incorporating accessible, user-friendly oxygen delivery solutions into public emergency response protocols has the potential to save lives and reduce long-term disability. Integration of devices such as the R15 into AED stations, public buildings, and first aid kits may represent a pivotal advancement in community-based resuscitation efforts.
