A Critical Review of the 2025 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care

The Utstein Formula for Survival, the ethos of the American Heart Association's 2025 guidelines for cardiopulmonary resuscitation and emergency cardiovascular care, is a conceptual model for survival of out-of-hospital cardiac arrest that equally weighs medical science, educational efficiency, and local implementation. With this formula in mind, the American Heart Association has put forth new guidelines that emphasize not only high-quality chest compressions and early defibrillation but also robust systems of care, equitable access, advanced resuscitation techniques, and postcardiac arrest recovery. The 2025 updates carry significant weight for health policy, clinical practice, education, and ethical discussions. In this review, we highlight the major changes, discuss their implications, and propose directions for future research and implementation.
