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

👉👉　🇺🇸 All Posts 🇬🇧 / 🇯🇵 記事一覧 🇯🇵　👈👈

♦️ Introduction

The American Heart Association has just 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.

If you want the full details, you can check the official document 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 big conceptual change this year is 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.

Now, the 2025 update simplifies everything into one universal six-link chain for all patients and settings:

💡 Clinical Pearl: Think beyond ROSC.
The addition of “Recovery” as the sixth link means our responsibility doesn’t end when the heart starts beating again. From preventing arrest to supporting rehab — we’re part of the whole continuum.

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

🔷 Core Components: Depth, Rate, and Recoil

The basics haven’t changed — but the wording is clearer and more practical. Here’s what to aim for:

👉 Keep these numbers in your head — they’re the foundation of effective CPR.

⚠️ Practical Tip — Defibrillation and Clothing Barriers

A real-world issue: women are less likely to receive bystander defibrillation, often due to hesitation about chest exposure.
The new guideline is clear — adjust clothing to place pads properly rather than delaying to remove it completely.

💡 Clinical Pearl: In-hospital, we usually remove clothing entirely — but never let modesty or clothing slow down a shock.

🫁 Airway and Ventilation — Oxygenation Comes First

🚑 Airway Management in Trauma Patients

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

If jaw thrust (with or without an oral/nasal airway) fails to open the airway, you should proceed to head-tilt–chin-lift.

Key Point 💡: Hypoxic brain injury is an immediate, life-threatening reality. Worsening a potential spinal cord injury is only a theoretical risk. The guidelines now explicitly support prioritizing oxygenation when initial maneuvers fail — because worrying about neurological damage while the patient suffers prolonged hypoxia or dies defeats the purpose.

👉 Don’t hesitate to act when needed. Document your clinical reasoning. If jaw thrust doesn’t work, move to head-tilt–chin-lift.

🫁 Ventilation Strategy for Respiratory Arrest

If the patient still has a pulse but poor breathing — common after opioids, residual paralysis, or deep sedation — provide 1 breath every 6 seconds (≈10 breaths/min) with visible chest rise, not big volumes.

💡 Clinical Pearl: The most common mistake is overventilation. Going too fast (20+ per minute) increases intrathoracic pressure, reduces venous return, and cuts off brain and heart perfusion. Stick to that steady 6-second rhythm. Nothing groundbreaking here — but the 2025 update reinforces avoiding both excessive tidal volumes and too-frequent breaths.

♦️ Choking and Special Scenarios

🔷 Foreign Body Airway Obstruction — Back Slaps First!

Big change here: for responsive adults and children, alternate between:

This aligns adult/child management with infants (who already use back slaps and chest thrusts).
If the patient becomes unresponsive, start CPR immediately and check the mouth before rescue breaths.

---

🔷 Mechanical CPR Devices — Still Limited Use

Routine use? Not recommended.
RCTs show no survival benefit over high-quality manual compressions.

But you can use mechanical CPR when manual compressions are impractical or unsafe, such as:

⚠️ New for 2025: Head-up CPR is not recommended outside clinical trials.

🎯 Optimizing Post-Cardiac Arrest Care

🫀 Hemodynamic Management — Simplified MAP Targets

Post-cardiac arrest blood pressure targets have been streamlined:

Earlier guidelines mentioned both SBP and MAP for adults, but the 2025 update focuses on MAP — simpler and evidence-based (think BOX trial). The key point: avoid hypotension.

The guidelines also suggest considering temporary mechanical circulatory support (VA-ECMO, etc.) for cardiogenic shock, a common cause of cardiac arrest.

💡 Pediatric CPR tip: During CPR with an arterial line in place, target diastolic blood pressure ≥25 mmHg in infants and ≥30 mmHg in children to ensure adequate coronary perfusion pressure.

---

🌡️ Temperature Management — 36-Hour Standard

For comatose survivors, maintain temperature between 32–37.5°C for at least 36 hours. This includes both therapeutic hypothermia and active normothermia (fever prevention).

💡 The new guideline provides a clearer target than the previous “at least 24 hours” — now 36 hours is the explicit minimum.

---

🧠 Neuroprognostication — Always Multimodal

Never rely on one test alone.
Evaluate the patient ≥72 hours after ROSC, once sedation is off, using:

• An early EEG without epileptiform activity may suggest a better outcome.
• Don’t treat non-epileptic myoclonus with anticonvulsants unless seizures are confirmed — the sedation risk outweighs the benefit.

📚 Education, Training, and Quality Improvement

🔷 CPR Feedback Devices — Now Class 1

Real-time feedback on compression depth, rate, and recoil is now a Class 1 recommendation for all training, both healthcare and lay rescuers.
It’s no longer optional — it’s the new standard.

---

🔷 Addressing Disparities in Care

The 2025 guidelines explicitly call for reducing disparities in CPR access and training:

---

🔷 Virtual Reality — Know Its Limits

• Useful for: learning algorithms and conceptual understanding
• Not for: psychomotor skills like compressions or airway management

VR can support learning but never replaces hands-on training.
