Question

What is the main difference between the CPR performed on teens, adults, and infants?

For teens and adults, alternate compressions and breathing.
For teens and adults, do compressions before calling 9-1-1.
For infants, perform chest compressions and rescue breathing.
For infants, check for signs of life and circulation first.

Answer 1

For infants only, perform chest compressions and rescue breathing.

Step-by-step explanation:

I took the same class.

Answer 2

For infants, check for signs of life and circulation first.
In infants and children, there's a more likely chance of airway blockage than adults. You should administer CPR FIRST, BEFORE CALLING 911.
Teens and adults are just the opposite: 911 FIRST!
