CPR Basics
What does CPR stand for?
Cardiopulmonary Resuscitation
What is the age range for an infant in CPR?
Under 1 year old
What is the first step when you find someone collapsed?
Check if the scene is safe
What does an AED do?
It analyzes heart rhythm and delivers a shock if needed to restore normal rhythm.
You see someone collapse at the mall. No one else is around. What’s the first thing you do?
Check if the scene is safe and assess responsiveness
How many compressions should be given per minute during adult CPR?
100–120 compressions per minute
What is the recommended compression depth for a child?
About 1.5 - 2 inches
After checking for responsiveness, what do you do next?
Call 911 or ask someone to do so
Where should you place AED pads on an adult?
One pad on the upper right chest and one on the lower left side.
You start compressions on a child and someone brings an AED. What do you do?
Stop CPR only to turn on and use the AED
How deep should chest compressions be for an adult?
At least 2 inches (5 cm)
How many fingers do you use for infant compressions?
Two fingers
If a person is gasping but not breathing normally, should you begin CPR?
Yes, start CPR immediately
Can you use an adult AED on a child or infant if no pediatric pads are available?
Yes, but place the pads so they do not touch (one on the front, one on the back).
You begin CPR on an unresponsive adult. After two cycles, the person vomits. What should you do next?
Quickly roll the person onto their side to clear the vomit from their mouth. Once the airway is clear, roll them back and resume CPR starting with chest compressions.
What is the compression to breath ratio for one rescuer CPR?
30 compressions to 2 breaths
What is one key difference in checking responsiveness in an infant versus an adult?
Tap the foot for infants instead of the shoulder
How long should you check for a pulse before starting compressions?
No more than 10 seconds
What should you do immediately after the AED delivers a shock?
Resume chest compressions right away.
During CPR on an adult, someone shows up with more training. What should you do?
Let them take over if they're more qualified and provide info on what you've done
You are performing CPR on an adult who suddenly starts showing signs of movement and begins to breathe normally but remains unresponsive. What is your next step, and why?
Stop CPR immediately and place the person in the recovery position (on their side) to keep the airway open and prevent choking. Continue to monitor breathing and responsiveness until EMS arrives.
Describe how the hand placement differs when performing compressions on adults, children, and infants.
Adult: two hands center of chest; Child: one or two hands center of chest; Infant: two fingers or two thumbs on sternum
What are the steps of CPR in the correct order (CAB)?
C: Compressions, A: Airway, B: Breaths
What safety step must you take before pressing the AED shock button?
Make sure no one is touching the victim—loudly say "Clear!"
You are giving CPR to an infant and a second rescuer arrives. How does the technique change?
Use the two-thumb encircling hands technique with a 15:2 compression-breath ratio
