Updated CPR Guidelines Introduce Major Changes to Choking Response and Opioid Overdose Treatment
The American Heart Association's 2025 CPR guidelines introduce significant updates including new choking protocols for all ages, expanded opioid overdose response with naloxone guidance, and a unified chain of survival system that could improve survival rates for the 350,000 annual out-of-hospital cardiac arrests in the U.S.
The American Heart Association released its 2025 Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care, marking the first comprehensive revision since 2020. Published in the Association's flagship journal Circulation, these updated recommendations address critical gaps in emergency response protocols that could significantly impact survival rates for common life-threatening situations.
Among the most notable changes are expanded recommendations for managing choking emergencies. The new guidance recommends alternating five back blows followed by five abdominal thrusts for conscious children and adults until the object is expelled or the person becomes unresponsive. This represents a significant departure from previous guidelines that did not include choking guidance for adults and recommended only abdominal thrusts for children. For infants, rescuers should now alternate between five back blows and five chest thrusts using the heel of one hand, with abdominal thrusts not recommended due to injury risks.
The guidelines also provide crucial new direction for treating suspected opioid overdoses, which account for 80% of all drug overdose deaths worldwide according to the World Health Organization. For the first time, the guidelines include public access instruction on when to use naloxone, a medication that reverses or reduces opioid effects. This addition comes as opioid-related emergencies continue to pose significant public health challenges globally.
Another fundamental change involves the consolidation of multiple chains of survival into a single system for all forms of cardiac arrest, whether adult or pediatric, in-hospital or out-of-hospital. This unified approach emphasizes the importance of performing both compressions and breaths, particularly for children and infants. The update reflects growing evidence that children as young as 12 can be taught effective CPR and defibrillation, potentially expanding the pool of trained responders in communities.
The timing of these updates is critical given current statistics. Approximately 350,000 people in the U.S. experience out-of-hospital cardiac arrests annually, with only about 41% receiving CPR before emergency medical services arrive according to the 2024 CARES Annual Report available at https://mycares.net/sitepages/uploads/2025/2024_flipbook/index.html. Early CPR intervention could double or triple survival chances, making improved public response essential.
Developed in collaboration with the American Academy of Pediatrics, the pediatric and neonatal guidelines include additional important updates. For most term and preterm infants not needing immediate resuscitation, delaying umbilical cord clamping for at least 60 seconds—double the previous recommendation—has been shown to improve newborn blood health and iron levels.
The guidelines recommend increased support for media campaigns, instructor-led training, and community education to improve lay-rescuer response to cardiac emergencies. These recommendations align with the Association's broader mission to train millions annually in CPR and first aid through programs implemented in over 90 countries worldwide.
