The American Heart Association has unveiled its most comprehensive update to CPR and Emergency Cardiovascular Care guidelines since 2020, introducing significant changes that promise to enhance lifesaving interventions for both medical professionals and everyday bystanders. Published on October 22, 2025, these evidence-based guidelines reflect the latest resuscitation science and address critical gaps in emergency response that have emerged over the past five years.
A Unified Approach: One Chain of Survival
One of the most notable changes is the consolidation of multiple chains of survival into a single, streamlined framework applicable to all cardiac arrests, regardless of patient age or location. Previously, separate chains existed for adults, children, infants, and for in-hospital versus out-of-hospital emergencies, creating potential confusion among responders and complicating training efforts.
This unified approach emphasizes five critical links: early recognition and prevention, activation of emergency response, high-quality CPR, rapid defibrillation, advanced resuscitation and post-cardiac arrest care, and recovery. By simplifying the framework, the AHA aims to make it easier for healthcare professionals and laypersons alike to remember and implement life-saving protocols during high-stress emergencies.
“The American Heart Association’s 2025 CPR guidelines represent gold standard science,” said Dr. Ashish Panchal, chair of the AHA’s Emergency Cardiovascular Care Science Committee and professor of emergency medicine at The Ohio State University. “As the science continues to evolve, it’s important that we continue to review new research specific to the scientific questions considered of greatest clinical significance.”

Revolutionary Choking Response Protocols
For the first time in AHA guideline history, specific guidance for responding to choking in conscious adults has been included. This addition addresses a common emergency that healthcare providers and civilians frequently encounter but for which clear, evidence-based protocols were previously lacking in official CPR guidelines.
Rescuers should now alternate five back blows with five abdominal thrusts in a continuous cycle until the obstruction is cleared or the person becomes unresponsive. This alternating approach has been shown to be more effective than relying solely on abdominal thrusts, as it utilizes different mechanisms to dislodge foreign objects from the airway.
For infants, the guidelines provide critical clarification that caregivers must use five back blows followed by five chest thrusts with the heel of one hand. Abdominal thrusts must be avoided in infants, as they can cause serious injury to fragile internal organs. This age-specific guidance helps prevent well-intentioned but potentially harmful interventions.

Mechanical CPR: A Nuanced Perspective
The 2025 update provides carefully nuanced guidance on mechanical CPR devices, which have been a topic of considerable debate in emergency medicine circles. While routine use of these devices is not recommended for adult cardiac arrest based on current evidence, the guidelines acknowledge specific scenarios where mechanical CPR may be considered as a reasonable alternative to manual compressions.
These situations include prolonged resuscitation during transport, in hazardous environments where manual CPR poses safety risks to healthcare professionals, or when consistent high-quality manual compressions cannot be reliably maintained. The key caveat: interruptions during device deployment and removal must be minimized, as any pause in compressions can significantly impact patient outcomes.
Numerous randomized controlled trials found no survival advantage with mechanical devices compared to high-quality manual CPR under normal circumstances. However, the guidelines acknowledge that unique clinical or logistical situations not fully represented in current research may justify their use, giving providers appropriate clinical discretion.
Routine use of mechanical CPR devices is not recommended, though they may be considered in specific scenarios such as prolonged resuscitation during transport or hazardous environments.
Neonatal and Pediatric Advances
In partnership with the American Academy of Pediatrics, the guidelines now recommend delaying umbilical cord clamping for at least 60 seconds—double the previous 30-second recommendation. This seemingly simple change can significantly improve newborn blood health and iron levels, providing benefits that extend well beyond the delivery room.
The pediatric updates also reflect new approaches to airway management and resuscitation timing. Dr. Javier Lasa, co-chair of the 2025 Pediatric Advanced Life Support Writing Group and associate professor at Children’s Health in Dallas, emphasized that “these guidelines underscore our shared commitment to protecting the youngest and most vulnerable lives.”
Remarkably, pediatric cardiac arrest survival rates have shown dramatic improvement, jumping from 18.9% to 45.2% between 2000 and 2023, thanks to early recognition of clinical deterioration and consistently high-quality CPR delivery.

The Critical Bystander Gap
Despite these advances in medical science and protocol development, statistics reveal a troubling gap: only 41% of adults who suffer cardiac arrest outside hospitals receive bystander CPR before EMS arrives. Yet research consistently demonstrates that early CPR can double or triple a person’s chances of survival.
The guidelines strongly emphasize expanded community training initiatives, media awareness campaigns, and accessible instructor-led courses to increase lay rescuer intervention rates.
Importantly, research shows that children as young as 12 can effectively learn CPR and automated external defibrillator (AED) operation, suggesting that CPR training should be integrated into school curricula nationwide.

Implementation Timeline and Training
The AHA and American Academy of Pediatrics are releasing updated training materials in multiple languages to accelerate global implementation of these guidelines. All AHA instructors must complete required science updates by February 28, 2026, ensuring these life-saving protocols reach healthcare providers and communities worldwide in a timely manner.
As Dr. Panchal emphasized, “We know high-quality CPR saves lives, and we need dedicated support to ensure that everyone who needs high-quality CPR receives it. That starts with learning it yourself. We encourage everyone to take a CPR class to learn the skills and techniques to provide life-saving care in an emergency. Everyone has a role to play in the chain of survival.”
