What is the first link in the Adult Chain of Survival?✔✔ Immediate recognition and activation of emergency response.
How does the Pediatric Chain of Survival differ from the Adult Chain?✔✔ It includes prevention, early CPR, EMS activation, advanced care, and post-resuscitation care.
Why is early defibrillation crucial in the Chain of Survival?✔✔ It increases survival rates by correcting shockable rhythms like VF/pulseless VT.
What is the final link in the Chain of Survival for both adults and children?✔✔ Recovery and post-cardiac arrest care.
How can bystanders strengthen the Chain of Survival?✔✔ By learning CPR, calling 911 immediately, and using an AED if available. 1 / 4
2
What is the correct compression depth for an infant during CPR?✔✔ Approximately 1.5 inches (4 cm).
How does the compression-to-ventilation ratio differ for a single rescuer on a child?✔✔ 30 compressions to 2 breaths (same as adult).
What is the key difference in infant CPR compared to adult CPR?✔✔ Use two fingers or the two-thumb encircling technique for compressions.
Why is allowing full chest recoil important in high-quality CPR?✔✔ It allows the heart to refill with blood between compressions.
How do you ensure effective breaths during infant CPR?✔✔ Cover the infant’s mouth and nose and deliver gentle puffs.
What is the recommended compression rate for all age groups?✔✔ 100–120 compressions per minute. 2 / 4
3
How should rescuers minimize interruptions during CPR?✔✔ Limit pauses to less than 10 seconds.
What is the correct hand placement for chest compressions on a child?✔✔ One or two hands on the lower half of the sternum.
Why is it important to switch rescuers every 2 minutes during CPR?✔✔ To prevent fatigue and maintain high-quality compressions.
What is the first step when using an AED on an adult?✔✔ Turn on the AED and follow voice prompts.
Can an AED be used on an infant?✔✔ Yes, preferably with pediatric pads or a pediatric dose-attenuating system.
What should you do if the victim has a medication patch where the AED pad needs to be placed?✔✔ Remove the patch and wipe the skin clean before applying the pad. 3 / 4
4
Why should you avoid touching the victim during AED analysis?✔✔ Movement can interfere with the AED’s rhythm detection.
What should you do if the AED says "No shock advised"?✔✔ Resume CPR immediately.
What is the role of the team leader during a resuscitation attempt?✔✔ Assign roles, give clear instructions, and ensure smooth coordination.
Why is closed-loop communication important in team CPR?✔✔ It prevents misunderstandings and ensures tasks are completed correctly.
How often should compressor rotations occur in team CPR?✔✔ Every 2 minutes or when fatigued.
What should the airway rescuer do while compressions are ongoing?✔✔ Prepare to give breaths and monitor for chest rise.
