Chest compressions are a vital component of cardiopulmonary resuscitation (CPR), used to manually circulate blood when the heart has stopped beating effectively. They are performed by pressing on the chest to mimic the heart’s pumping action, helping to deliver oxygen to vital organs until advanced medical help arrives.
Key Steps for Performing Chest Compressions:
Positioning: Place the person on a firm, flat surface. For an adult or child, kneel beside them and position the heel of one hand on the center of the chest, between the nipples. Place your other hand on top, interlocking your fingers.
Depth and Rate: Compress the chest at least 2 inches (5 cm) deep for adults, about 1.5 to 2 inches (4 to 5 cm) for children, and about 1.5 inches (4 cm) for infants. Aim for a rate of 100 to 120 compressions per minute.
Technique: Push hard and fast, allowing the chest to fully recoil between compressions. Use your body weight to ensure effective pressure, keeping your arms straight and shoulders directly over your hands.
Chest compressions can be physically demanding, so switch rescuers every 2 minutes if possible. Proper training from certified organizations like the American Heart Association or Red Cross is recommended to ensure safety and effectiveness. Risks include rib fractures, but these are outweighed by the potential to save a life.

Part 2: 20 chest compressions quiz questions & answers
or
1. Question: What is the recommended depth for chest compressions on an adult during CPR?
A. At least 1 inch (2.5 cm)
B. At least 1.5 inches (4 cm)
C. At least 2 inches (5 cm)
D. At least 3 inches (7.5 cm)
Answer: C
Explanation: The recommended depth for adult chest compressions is at least 2 inches (5 cm) to ensure adequate blood flow to vital organs.
2. Question: What is the ideal rate for performing chest compressions during CPR?
A. 60-80 compressions per minute
B. 80-100 compressions per minute
C. 100-120 compressions per minute
D. 120-140 compressions per minute
Answer: C
Explanation: The ideal rate is 100-120 compressions per minute to maintain effective circulation without causing fatigue.
3. Question: Where should you place your hands for chest compressions on an adult?
A. On the upper chest near the neck
B. On the center of the chest, on the lower half of the sternum
C. On the abdomen
D. On the side of the ribcage
Answer: B
Explanation: Hands should be placed on the lower half of the sternum to compress the heart effectively between the sternum and spine.
4. Question: What should you ensure after each chest compression?
A. Hold the compression for 5 seconds
B. Allow full chest recoil
C. Apply additional pressure
D. Switch hands immediately
Answer: B
Explanation: Allowing full chest recoil ensures that the heart can refill with blood, improving overall CPR effectiveness.
5. Question: In CPR for an adult, what is the compression-to-ventilation ratio for one rescuer?
A. 15 compressions to 1 breath
B. 15 compressions to 2 breaths
C. 30 compressions to 1 breath
D. 30 compressions to 2 breaths
Answer: D
Explanation: The standard ratio is 30 compressions to 2 breaths for one rescuer, allowing for effective oxygen delivery and circulation.
6. Question: What is the primary purpose of chest compressions during CPR?
A. To provide oxygen to the lungs
B. To manually pump blood through the body
C. To clear airway blockages
D. To monitor heart rhythm
Answer: B
Explanation: Chest compressions mimic the heart’s pumping action, circulating blood to vital organs when the heart has stopped.
7. Question: How should you position the victim before starting chest compressions?
A. On their stomach
B. On their side
C. On their back on a firm surface
D. Sitting up
Answer: C
Explanation: The victim should be on their back on a firm surface to allow for effective and uninterrupted compressions.
8. Question: What is the correct hand position for chest compressions on a child?
A. One hand on the upper chest
B. Two hands on the lower chest
C. One or two hands on the center of the chest
D. Fingers only on the sternum
Answer: C
Explanation: For children, use one or two hands on the center of the chest, depending on the child’s size, to provide adequate compression.
9. Question: During CPR, how deep should chest compressions be for a child?
A. At least 1 inch (2.5 cm)
B. At least 1.5 inches (4 cm)
C. At least 2 inches (5 cm)
D. At least 2.5 inches (6 cm)
Answer: C
Explanation: For children, compress at least 2 inches (5 cm) or one-third the depth of the chest to ensure effective circulation.
10. Question: What could happen if chest compressions are too shallow?
A. Increased risk of rib fractures
B. Ineffective blood circulation
C. Faster fatigue for the rescuer
D. Over-ventilation
Answer: B
Explanation: Shallow compressions fail to generate enough pressure to circulate blood adequately, reducing the chances of survival.
11. Question: In what scenario should you stop chest compressions?
A. When the victim shows signs of life
B. After 2 minutes regardless
C. Only if another rescuer takes over
D. When emergency services arrive
Answer: A
Explanation: Stop compressions if the victim regains consciousness or shows signs of life, as continued CPR could be harmful.
12. Question: What is the minimum age for using two hands for chest compressions?
A. Infants only
B. Children under 1 year
C. Adults and children over 1 year
D. All ages
Answer: C
Explanation: Two hands are typically used for adults and children over 1 year to provide sufficient force for effective compressions.
13. Question: How can you minimize interruptions during chest compressions?
A. By checking for a pulse every 30 seconds
B. By switching rescuers every 2 minutes
C. By performing compressions continuously
D. By stopping to give breaths every minute
Answer: C
Explanation: Minimizing interruptions ensures better blood flow and higher survival rates during CPR.
14. Question: What feedback device might be used to guide chest compression depth?
A. A stethoscope
B. A CPR feedback device or metronome
C. A blood pressure cuff
D. An oxygen mask
Answer: B

A. With two hands on the chest
B. With two fingers on the chest
C. With the heel of one hand
D. With full body weight
Answer: B
Explanation: For infants, use two fingers to perform compressions on the center of the chest to avoid excessive force.
16. Question: What is the risk of performing chest compressions too quickly?
A. Incomplete chest recoil
B. Reduced compression depth
C. Ineffective ventilation
D. All of the above
Answer: D
Explanation: Performing compressions too quickly can lead to incomplete recoil, shallower depth, and poor overall CPR quality.
17. Question: In a team CPR scenario, how often should rescuers switch roles?
A. Every 30 seconds
B. Every 1 minute
C. Every 2 minutes
D. Every 5 minutes
Answer: C
Explanation: Switching every 2 minutes helps prevent rescuer fatigue and maintains the quality of chest compressions.
18. Question: What should you do if the chest does not rise during CPR?
A. Continue compressions only
B. Recheck airway and give another breath
C. Stop CPR entirely
D. Increase compression depth
Answer: B
