Final answer:
After an AED delivers a shock to an infant, you should resume CPR at a ratio of 30 compressions to 2 breaths.
Step-by-step explanation:
After an Automated External Defibrillator (AED) delivers a shock to an infant, you should resume CPR at a ratio of 30 compressions to 2 breaths. This is the same ratio used for adult CPR. It is important to deliver chest compressions at a rate of at least 100-120 compressions per minute and to allow for complete chest recoil after each compression. When delivering breaths, make sure to provide a gentle puff of air that results in visible chest rise.
