What action is recommended early on in a pediatric cardiac arrest?

• A. Ventilation
• B. Chest compressions
• C. Defibrillation
• D. Epinephrine administration

Answer: (A)

In pediatric cardiac arrest, the most common trigger is respiratory failure leading to hypoxia, so getting ventilation started early is the most effective initial step. Providing rescue breaths helps re-oxygenate the blood, which supports brain and heart tissue and makes subsequent chest compressions more effective. While chest compressions are essential, addressing the airway and oxygenation first tackles the root cause in most kids and improves the chances of successful resuscitation. Defibrillation is less likely to be immediately useful because pediatric arrests are frequently non-shockable rhythms, epinephrine is important but comes after initiating CPR with ventilation, and chest compressions alone won’t be as beneficial without oxygen delivery.
