🚨 AHA CPR/ECC Guidelines Updated! -What’s New Since 2020?🤔

👉👉　🇺🇸 All Posts 🇬🇧 / 🇯🇵 記事一覧 🇯🇵　👈👈

♦️ Introduction

The American Heart Association has released its comprehensive 2025 Guidelines for Cardiopulmonary Resuscitation (CPR) and Emergency Cardiovascular Care (ECC).

These updated recommendations reflect the latest evidence in resuscitation science and bring several important changes that matter for those of us working in the perioperative and critical care world.

For complete details, please visit the official guidelines at eccguidelines.heart.org.

Here, we’ll focus on what’s new compared to 2020, especially updates that affect your day-to-day work in the OR, PACU, or ICU.

As anesthesiologists, surgeons, and critical care nurses, we’re often the first in-hospital responders when a crisis hits. Cardiac arrest during surgery is rare — but how we respond makes all the difference. Let’s go through the 2025 updates that will help you provide fast, effective, evidence-based care👍

🔗 The Chain of Survival — Now Unified

One significant conceptual change is the approach to the Chain of Survival.

Previously, there were four separate chains — adult in-hospital, adult out-of-hospital, pediatric in-hospital, and pediatric out-of-hospital.

The 2025 update simplifies this into one universal framework applicable to all patients and settings. This unified approach encompasses the complete continuum of care from initial recognition through long-term recovery, emphasizing that resuscitation extends beyond return of spontaneous circulation.

For the specific components of this unified chain, please refer to the official guidelines.

💡 Clinical Pearl: Think beyond ROSC. The framework now explicitly includes recovery and survivorship, meaning our responsibility doesn’t end when the heart starts beating again. From preventing arrest to supporting rehabilitation — we’re part of the whole continuum.

♦️ Mastering High-Quality CPR — What’s Changed?

🔷 Core Components: Depth, Rate, and Recoil

The fundamental principles haven’t changed dramatically — but the wording is clearer and more practical. Key elements of high-quality CPR include:

👉 These principles form the foundation of effective CPR and should be thoroughly understood.For precise numerical targets and detailed specifications, please consult the official guidelines.

⚠️ Practical Consideration — Defibrillation and Clothing

A real-world issue that affects care: women are less likely to receive bystander defibrillation, often due to concerns about chest exposure.

The guidelines clarify that clothing should be adjusted as needed to place defibrillation pads properly, rather than delaying to completely remove garments. The priority is rapid defibrillation.

💡 Clinical Pearl: In-hospital settings typically involve complete clothing removal for full patient access — but the key principle is never allowing clothing concerns to delay defibrillation.

🫁 Airway and Ventilation — Oxygenation Comes First

🚑 Airway Management in Trauma Patients

The traditional approach emphasized “jaw thrust only when cervical spine injury is suspected” — but the 2025 guidelines add an important clinical qualifier.

If jaw thrust (with or without an oral/nasal airway) fails to establish an adequate airway, clinicians should proceed to head-tilt–chin-lift maneuvers.

Key Clinical Principle 💡: Hypoxic brain injury represents an immediate, life-threatening reality. The potential for worsening a spinal cord injury, while important to consider, is a theoretical risk that must be balanced against the certain harm of prolonged hypoxia. The guidelines now explicitly support prioritizing oxygenation when initial conservative maneuvers prove inadequate — because protecting against theoretical neurological harm while the patient suffers definite hypoxic injury or dies is counterproductive.

👉 Clinical Application: Don’t hesitate to escalate airway interventions when clinically indicated. Document your clinical reasoning. If jaw thrust doesn’t establish adequate ventilation, progress to head-tilt–chin-lift.

🫁 Ventilation Strategy for Respiratory Arrest

When a patient maintains a pulse but has inadequate breathing — commonly seen after opioid administration, residual neuromuscular blockade, or deep sedation — the recommended approach is approximately one breath every 6 seconds (roughly 10 breaths per minute), delivering sufficient volume to produce visible chest rise without excessive tidal volumes.

💡 Clinical Pearl: The most common error in this scenario is overventilation. Excessive respiratory rates (exceeding 15-20 per minute) increase intrathoracic pressure, reduce venous return, and compromise cerebral and coronary perfusion. Maintain a steady, measured ventilation rhythm.

The 2025 update reinforces the importance of avoiding both excessive tidal volumes and overly frequent ventilations — principles that remain critical to optimal outcomes.

♦️ Choking and Special Scenarios

🔷 Foreign Body Airway Obstruction — Updated Approach

A notable change for responsive adults and children with severe airway obstruction: the recommended approach now involves alternating between back slaps and abdominal thrusts (noting that abdominal thrusts are not recommended for infants, who should receive chest thrusts instead).

This approach continues until the obstruction is relieved or the patient becomes unresponsive. The updated algorithm aligns adult/child management more closely with the approach already used for infants.

If the patient becomes unresponsive, immediately begin CPR and visually check the mouth before attempting rescue breaths.

For specific technique details and the number of interventions in each cycle, please refer to the official guidelines.

🔷 Mechanical CPR Devices — Still Limited Use

Routine use of mechanical CPR devices continues to be not recommended based on current evidence. Multiple large randomized controlled trials have not demonstrated survival benefit over high-quality manual chest compressions.

However, mechanical CPR may be considered in specific situations where manual compressions are impractical or pose safety concerns, such as:

⚠️ New for 2025: Head-up CPR positioning is not recommended for use outside of clinical trials at this time.

🎯 Optimizing Post-Cardiac Arrest Care

🫀 Hemodynamic Management — Streamlined Approach

Post-cardiac arrest blood pressure management has been clarified:

Earlier guidelines referenced both SBP and MAP targets for adults, but the 2025 update emphasizes MAP as the primary target — a simpler, evidence-based approach informed by major clinical trials. The fundamental goal remains avoiding hypotension, which adversely affects outcomes.

The guidelines also suggest considering temporary mechanical circulatory support (such as VA-ECMO) for post-arrest cardiogenic shock, a frequent underlying cause of cardiac arrest.

💡 Pediatric CPR consideration: During CPR in children with arterial line monitoring, target diastolic blood pressures of approximately 25 mmHg in infants and 30 mmHg in children to help ensure adequate coronary perfusion pressure.

🌡️ Temperature Management — 36-Hour Standard

For comatose survivors of cardiac arrest, the recommendation is to maintain body temperature within the range of 32-37.5°C for at least 36 hours. This encompasses both therapeutic hypothermia strategies and active normothermia (prevention of fever).

💡 The updated guideline provides clearer duration guidance than the previous “at least 24 hours” recommendation — 36 hours is now the explicit minimum duration.

🧠 Neuroprognostication — Always Multimodal

Never rely on a single indicator for neurologic prognosis.

Evaluation should occur at least 72 hours after return of spontaneous circulation, once sedative medications have been discontinued, and should incorporate multiple assessment modalities:

Early EEG findings without epileptiform activity, when combined with other favorable indicators, may suggest better neurologic outcomes.

Important clinical note: Do not treat non-epileptic myoclonus with antiepileptic medications unless seizure activity is confirmed on EEG — the risks of sedation may outweigh potential benefits in these cases.

📚 Education, Training, and Quality Improvement

🔷 CPR Feedback Devices — Now Strongly Recommended

Real-time feedback devices that monitor compression depth, rate, and recoil are now strongly recommended (Class 1) for all CPR training, encompassing both healthcare providers and lay rescuers.

This technology has transitioned from optional enhancement to standard of care in training programs.

---

🔷 Addressing Disparities in Care

The 2025 guidelines explicitly emphasize reducing disparities in CPR access, training, and outcomes:

🔷 Virtual Reality — Understanding Appropriate Use

Virtual reality technology shows promise for specific educational applications:

• Appropriate use: Learning cognitive aspects — algorithms, decision pathways, conceptual understanding
• Not recommended for: Developing psychomotor skills such as chest compressions or airway management techniques

VR can effectively supplement traditional training but should not replace hands-on skill development.
