2026–2027 ACLS CLINICAL GUIDELINES UPDATES
ACLS training is dynamic, reflecting continuous advancements in resuscitation science. Below is a
high-yield summary of the core clinical differences between older protocols (such as 2010/2015
standards) and the modern 2026–2027 AHA Guidelines for CPR and ECC.
Key AHA 2026-2027 Guidelines Highlights
• Chest Compression Rate and Depth: Confirmed at 100 to 120 compressions/minute (with a hard ceiling at
120) and a depth of 2.0 to 2.4 inches (5 to 6 cm) to optimize perfusion without causing excess chest wall trauma
[4, 9, 21].
• Immediate Epinephrine for Non-Shockable Rhythms: For PEA or asystole, administer epinephrine (1 mg
IV/IO) immediately (within 5 minutes of arrest onset) rather than waiting until after the first CPR cycle [11, 19].
• TTM Duration & Target: Targeted Temperature Management is recommended for all comatose survivors of
cardiac arrest, maintaining a target between 32°C and 36°C for a continuous duration of at least 24 hours [23, 24].
• Oxygen Post-ROSC: Titrate FiO2 to maintain SpO2 between 92% and 98% (or PaO2 80-100 mm Hg).
Hyperoxia (excessive oxygen administration) causes oxidative stress and free radical production, worsening brain
injury [24].
• Rescue Breathing in Respiratory Arrest: Standardized to 1 breath every 6 seconds (10 breaths/minute) for
adults with a pulse to prevent hypocapnia-induced vasoconstriction [18].
Commonly Confused ACLS Concepts
• Defibrillation vs. Synchronized Cardioversion: Defibrillation is high-energy, unsynchronized, and
delivered immediately for pulseless rhythms (VF/pVT) [4, 8]. Synchronized cardioversion is synchronized
to the R-wave of the QRS complex to avoid the vulnerable refractory period (R-on-T phenomenon) and is
used only for patients with a pulse who are hemodynamically unstable [14, 15, 17, 20].
• Epinephrine Dosing: Epinephrine in cardiac arrest is 1 mg IV/IO push every 3 to 5 minutes [8, 9].
Epinephrine for post-ROSC hypotension support is given as an infusion at 0.1 to 0.5 mcg/kg/minute (or 2
to 10 mcg/minute), titrated to patient response. Never give an IV push of epinephrine to a patient with a
pulse [24, 25].

CHAPTER 1: BASIC LIFE SUPPORT (BLS) AND HIGH-QUALITY
CPR
Question 1
What should be done to minimize interruptions in chest compressions during CPR?
A. Perform pulse checks only after defibrillation.
B. Continue CPR while the defibrillator is charging.
C. Administer IV medications only when breaths are given.
D. Continue to use AED even after the arrival of a manual defibrillator.
ANSWER ■: B — Continue CPR while the defibrillator is charging.
Explanation: To minimize interruptions in chest compressions, the resuscitation team should continue CPR
while the defibrillator is charging. Interruptions in chest compressions decrease coronary perfusion pressure and
reduce the likelihood of return of spontaneous circulation (ROSC). Continuous chest compressions must be
maintained until the shock is ready to be delivered.
Why other options are incorrect:
• A: Pulse checks should not be routinely performed after defibrillation; instead, chest compressions must
resume immediately after shock delivery without waiting.
• C: IV/IO medications are administered rapidly during active chest compressions, not when ventilations are
being given.
• D: A manual defibrillator should replace an AED once available, as it allows for advanced rhythm analysis and
manual energy titration.
