Healthcare professionals renewing Advanced Cardiovascular Life Support (ACLS) certification in 2026 may encounter updated recommendations that differ from the protocols they learned previously. The American Heart Association’s 2025 guidelines address several areas of advanced resuscitation, including vascular access during cardiac arrest, treatment of persistent shockable rhythms, and the use of point-of-care ultrasound.
Understanding the reasoning behind these recommendations can help experienced clinicians prepare for updated course materials without treating ACLS renewal as a simple review of familiar algorithms.
1. Intravenous Access Is the Preferred Initial Approach
One important change concerns vascular access during adult cardiac arrest. The 2025 AHA guidelines recommend attempting intravenous (IV) access before intraosseous (IO) access when administering medications.
Previous training may have presented both routes as options without the same emphasis on which to attempt first. Current guidance prioritizes IV access, while IO access remains a reasonable alternative when IV attempts are unsuccessful or IV access is not feasible.
This distinction matters in clinical practice because the preferred initial approach should reflect current evidence without delaying essential resuscitation. Healthcare providers should understand when to move to an alternative access route while maintaining attention to high-quality CPR and timely defibrillation.
2. Refractory VF and pVT: What the Evidence Says
Ventricular fibrillation (VF) and pulseless ventricular tachycardia (pVT) can persist despite repeated defibrillation attempts. In these situations, clinicians may encounter discussions of vector-change defibrillation and double sequential external defibrillation.
However, the 2025 AHA guidelines state that the usefulness of both approaches for shock-refractory VF or pVT has not been established. Their potential benefits remain uncertain, and further research is needed.
For ACLS candidates, the key takeaway is not to assume that these techniques are established solutions when standard defibrillation fails. Updated training should reinforce evidence-based resuscitation priorities and clarify the difference between an intervention being investigated and one supported by established recommendations.
3. The Limited Role of Point-of-Care Ultrasound
Point-of-care ultrasound (POCUS) can help experienced clinicians investigate potentially reversible causes of cardiac arrest. However, its use during active resuscitation requires careful judgment.
The AHA guidelines state that the usefulness of POCUS for diagnosing reversible causes during adult cardiac arrest is not well established. Its use may be considered by experienced professionals when it does not interrupt resuscitative efforts, particularly chest compressions.
This qualification is essential. Ultrasound should not create avoidable pauses in CPR or distract the resuscitation team from established priorities. Clinicians should understand both its potential diagnostic value and its limitations during cardiac arrest.
