Adding Purpose to Pulse: 2025 Pediatric Life Support Update.

The American Heart Association (AHA) revised the Pediatric Basic and Advanced Life Support guidelines in 2025 to reflect on the current evidence and best practices. The key changes include a special emphasis on post-cardiac arrest care, prognostication, and survivorship. Other major changes include the elimination of 2-finger chest compressions in infants with a recommendation of compressing the chest with the heel-of-1-hand technique or 2-thumb-encircling hands technique; the preferential and immediate use of an automated external defibrillator with a pediatric attenuator, if available, for cardiac arrest; and in children with severe foreign-body airway obstruction repeated cycles of 5 back blows alternating with 5 abdominal thrusts.
