2015 AHA ECC Guidelines – Part 1
As a trusted provider of ACLS , BLS , and PALS certification, we keep a close eye on the latest recommendations for emergency cardiovascular care (ECC), which are updated by the American Heart Association (AHA) every five years.
If you’re wondering what’s changed in the 2025 AHA ECC Guidelines, look no further. Below, we’ll dive into some of the new and updated recommendations. We’ll explain the updates, the reasons behind them, and how they might change systems of care moving forward.
This is part 1 of a 2-part series, so keep an eye out for the next installment!

Continued Focus: Systems of Care and Continuous Quality Improvement
Two important concepts were introduced a decade ago in the 2015 AHA ECC update: systems of care and continuous quality improvement.
The basic concept was that for each patient to survive cardiac arrest, they depend on integrated systems of people, training, equipment, and organizations. A commitment to quality improvement across all of these systems is essential for a successful outcome.
These concepts remain a core focus in the 2025 AHA ECC Guidelines and are consistently threaded throughout the updated topics.
Update: Unified Chain of Survival
While the AHA’s 2015 and 2020 updates focused on separating chains of care based on adult versus pediatric and in- versus out-of-hospital (IHCA vs OHCA), the 2025 guidelines move toward a single unified chain of survival for everyone, as follows:
The goal of the unified chain is to simplify messaging and reinforce a consistent approach for populations like lay rescuers, EMS personnel, hospital staff, and system planners.
Update: A Clarified Role for Mechanical CPR Devices
As of 2025, the use of mechanical CPR devices is no longer universally recommended for adult resuscitation due to a lack of demonstrable difference in patient survival.
However, the guidelines do note that there may be specific circumstances where the use of mechanical CPR devices may provide logistical or safety advantages, such as during transport, in a hazardous environment, or with prolonged resuscitations where there are limited numbers of compressors. In these situations, care should be taken to strictly limit interruptions in CPR during the deployment and removal of the device.
Update: Community Rescuer Engagement & Technology Integration
The 2025 guidelines place an emphasis on the need for media campaigns and community training to improve lay rescuer response time.
They also suggest that one path to increasing willingness to aid as well as self-confidence to do so lies in early introduction to the concepts of emergency calls, CPR, and automatic external defibrillators (AEDs) to school children younger than 12.
Another piece of the community rescuer engagement recommendations involves leveraging technology. For example, using app notifications or text messages to alert willing lay rescuers to cardiac arrest events could improve response time to improve lay rescuer CPR and defibrillation response times.
Update: Improved Public Access Defibrillation (PAD)
Timely defibrillation is a cornerstone to effective resuscitation, so another area advanced by the 2025 AHA ECC guidelines is to improved public access to automatic external defibrillators.
There are multiple components to this goal. Resources for locating the nearest AED need to be developed, including public registration of AED locations with emergency services and integration into electronic mapping systems and mobile apps. Emergency dispatchers are also encouraged to direct lay rescuers to retrieve and use AEDs clearly and promptly.
The guidelines also advise against the common practice of locking public access AED cabinets, since these barriers can cause delays in AED use. If locks are used, they recommend that there are clear instructions for how to gain access available.
Update: Choking Response Enhancements
The 2025 guidelines also provide updated guidance for foreign body airway obstruction (FBAO) response.
For conscious adults, updated recommendations include alternating five back blows and five abdominal thrusts until the object is expelled or the person becomes unresponsive. This reflects research indicating that back blows can be more effective and less injurious than abdominal thrusts alone.
The algorithm is as follows:
For choking infants, updated recommendations involve five back blows then five chest thrusts using the heel of one hand. Abdominal thrusts are no longer recommended for infants due to the potential for abdominal organ injury but may still be used for older children.
Update: Special Circumstances of Resuscitation
The 2025 AHA ECC Guidelines have a new section for special circumstance resuscitations, whether they occur in adults or children.
Many recommendations fall under this new section. We’ll highlight some of the recommendation areas below.
Opioid Overdose
For the first time, the 2025 guidelines include public access to and instruction on naloxone use in a suspected opioid overdose, connecting resuscitation science with the broader public health and systems-of-care context.
The recommendation comes due to an association of naloxone use with decreased mortality and the lack of any known harm from naloxone administration to a person in cardiac arrest, as long as it doesn’t interfere with standard resuscitation.
The 2025 guidelines also call for public policies that allow for possession, use and immunity from civil and criminal liability for good-faith administration of naloxone by lay rescuers. The recommendations cite studies showing that legislation which protects lay rescuers, along with public access to naloxone, is generally associated with reductions in mortality.
The Use of Extra-Corporeal Life Support (ECLS)
The main recommendation of this section is that when cardiac arrest had a reversible cause that has not yet been reversed – asthma exacerbation, hyperkalemia, hypothermia, , or hyperthermia, to name a few – the use of extra-corporeal life support (ECLS) devices may be reasonable to improve survival rates or favorable neurological outcomes.
Different methodologies are recommended based on the circumstances.
Resuscitative Delivery
During cardiac arrest in a pregnant person, resuscitative delivery – which has replaced the term “perimortem cesarian delivery” – within the first five minutes of arrest can improve outcomes for the pregnant patient.
As a result, the 2025 guidelines recommend preparing for resuscitative delivery immediately at the recognition of cardiac arrest in a pregnant person.
The 2025 algorithm for cardiac arrest in pregnancy also accounts for other considerations and interventions, like ECLS and balanced massive transfusion for a suspected amniotic fluid embolism.
Unresponsive Patients with LVADs
Left ventricular assist devices (LVADs) cause the absence of a palpable pulse, which makes determining cardiac arrest in unresponsive adults or children with LVADs difficult.
The new recommendations suggest that for durable LVAD patients, chest compressions should be started immediately while a second rescuer attempts to restore LVAD function. This is because the potential benefit of CPR outweighs a theoretical risk of dislodgement.
