Pediatric Cardiac Arrest Algorithm - 2025 Guidelines Coming Soon

Bradycardia acls algorithm

When a child’s heart stops beating, every second counts. The pediatric cardiac arrest algorithm provides healthcare providers with a systematic approach to resuscitate young patients effectively. This evidence-based protocol can mean the difference between life and death for children experiencing cardiac emergencies.

Healthcare professionals who work with pediatric patients must understand this algorithm inside and out. Whether you’re a nurse, physician, or emergency responder, mastering these steps will prepare you to act quickly and confidently when facing one of medicine’s most critical situations.

The pediatric cardiac arrest algorithm follows specific guidelines developed by the American Heart Association. These protocols have been refined through years of research and real-world application, giving medical teams the best chance of achieving successful outcomes.

What is the Pediatric Cardiac Arrest Algorithm?

The Pediatric Cardiac Arrest Algorithm is a systematic guide developed by organizations like the American Heart Association (AHA) for managing cardiac arrest in infants and children. It prioritizes high-quality CPR and identifies the underlying cause of the arrest to guide treatment.

The algorithm is split into two main pathways based on the child’s heart rhythm:

  • Shockable Rhythms: Ventricular Fibrillation (VF) and pulseless Ventricular Tachycardia (pVT).
  • Non-Shockable Rhythms: Asystole and Pulseless Electrical Activity (PEA).

Promptly identifying the rhythm is crucial, as it determines whether defibrillation is needed.

The Core Components of Pediatric Resuscitation

Regardless of the specific rhythm, the foundation of the Pediatric Cardiac Arrest Algorithm is built on several key actions. These must be performed quickly and efficiently.

Start High-Quality CPR Immediately

As soon as you recognize a child is in cardiac arrest, start CPR. This is the single most important intervention. High-quality CPR for children involves:

  • Rate: 100 to 120 compressions per minute.
  • Depth: Compress the chest about 1.5 inches (4 cm) for infants and 2 inches (5 cm) for children.
  • Recoil: Allow the chest to fully recoil between compressions.
  • Minimizing Interruptions: Keep pauses in chest compressions as short as possible.

The compression-to-ventilation ratio is 30:2 for a single rescuer and 15:2 for two rescuers.

Attach the Monitor/Defibrillator

While CPR is in progress, another team member should attach a monitor or defibrillator to the child. This allows for a quick rhythm check to determine if the rhythm is shockable or non-shockable. This analysis should happen during a brief pause in compressions, ideally lasting no more than 10 seconds.

Managing Shockable Rhythms: VF and pVT

If the rhythm check reveals Ventricular Fibrillation (VF) or pulseless Ventricular Tachycardia (pVT), the immediate action is to deliver a shock.

Step 1: Deliver the Shock

The recommended initial energy dose for defibrillation in children is 2 joules per kilogram (J/kg) of the child’s weight. If a second shock is needed, the dose can be increased to 4 J/kg. Subsequent shocks can be administered at doses up to 10 J/kg or the maximum adult dose.

Step 2: Resume CPR Immediately

As soon as the shock is delivered, resume high-quality CPR for two minutes. Do not pause to check for a pulse right away. The goal is to maximize blood flow to the brain and other vital organs.

Step 3: Administer Epinephrine

If the child remains in cardiac arrest after the first two minutes of CPR post-shock, establish IV or IO (intraosseous) access. Administer epinephrine every 3 to 5 minutes. Epinephrine helps constrict blood vessels, increasing blood pressure and blood flow to the heart.

Step 4: Consider Advanced Airway and Antiarrhythmics

After the second shock, you may consider placing an advanced airway, such as an endotracheal tube. If VF or pVT persists, administering an antiarrhythmic medication like Amiodarone or Lidocaine may be necessary. These medications can help stabilize the heart’s rhythm.

Continue this cycle of CPR, rhythm checks, shocks, and medication until the child achieves Return of Spontaneous Circulation (ROSC) or resuscitation efforts are stopped.

Managing Non-Shockable Rhythms: Asystole and PEA

If the rhythm check shows Asystole (a flat line) or Pulseless Electrical Activity (PEA), the approach is different because shocks are not effective.

Step 1: Administer Epinephrine

For non-shockable rhythms, the priority is to administer epinephrine as soon as IV/IO access is available. Continue giving it every 3 to 5 minutes throughout the resuscitation effort.

Step 2: Continue High-Quality CPR

Resume CPR immediately after the rhythm check. Since defibrillation is not an option, continuous, high-quality CPR is the primary treatment. The cycle remains two minutes of CPR followed by a rhythm check.

Step 3: Identify and Treat Reversible Causes

While performing CPR, it is vital to search for and treat any reversible causes of the cardiac arrest. These are often remembered by the “H’s and T’s”:

  • Hypovolemia (low blood volume)
  • Hypoxia (low oxygen)
  • Hydrogen ion (acidosis)
  • Hypo/Hyperkalemia (potassium imbalance)
  • Hypoglycemia (low blood sugar)
  • Hypothermia (low body temperature)
  • Tension pneumothorax
  • Tamponade (cardiac)
  • Toxins
  • Thrombosis (pulmonary or coronary)

Addressing these underlying issues is often the key to achieving ROSC in cases of Asystole or PEA.

Post-Resuscitation Care

If the team successfully achieves ROSC, the work is not over. Post-cardiac arrest care is critical for improving the child’s chances of a good outcome. This includes optimizing ventilation and oxygenation, treating hypotension, and managing the child’s temperature to protect the brain.

Gain Confidence with Hands-On Training

Reading about the Pediatric Cardiac Arrest Algorithm is a great first step, but true competence comes from hands-on practice.
