What is the recommended order of steps at the start of a pediatric resuscitation scenario?

• A. Check responsiveness, call for help, start CPR, call EMS, get IV/IO access, defibrillate if shockable.
• B. Call EMS first, then check responsiveness, start CPR, obtain IV access, defibrillate.
• C. Start CPR only after ROSC.
• D. Ventilate first.

Answer: (A)

The main idea is to maximize perfusion as quickly as possible while mobilizing help and preparing advanced care. In a pediatric arrest, you don’t wait to see if the child will respond—you act fast. Start by checking responsiveness to confirm the arrest, then immediately call for help so a code team and a defibrillator are en route. Begin high-quality chest compressions right away to maintain blood flow to the heart and brain; interruptions should be minimized because every second of delay reduces likelihood of return of spontaneous circulation and worsens neurological outcome. While CPR is ongoing, ensure that EMS or the code team is on the way and ready to provide advanced care. Establish IV or IO access during ongoing CPR so drugs can be delivered without pausing compressions. Finally, assess the rhythm and defibrillate if a shockable rhythm is present, since delivering a shock can restore a perfusing rhythm when appropriate. This order emphasizes rapid CPR, swift activation of help, timely vascular access, and defibrillation when indicated, all critical for pediatric outcomes.
