How deep should chest compressions be on an average adult?
Answer: At least 2 inches (5 cm)
Adult compressions should be at least 2 inches but no more than 2.4 inches deep.
What is the correct compression-to-ventilation ratio for one-rescuer adult CPR?
Answer: 30:2
A single rescuer gives 30 compressions followed by 2 breaths for an adult.
Why is allowing full chest recoil important between compressions?
Answer: It lets the heart refill with blood
Full recoil allows the heart to refill so the next compression can pump effectively.
Where should your hands be placed for adult chest compressions?
Answer: On the center of the chest, lower half of the sternum
Hands go on the center of the chest over the lower half of the breastbone.
How long should interruptions in chest compressions ideally last?
Answer: Less than 10 seconds
Pauses in compressions should be limited to less than 10 seconds to maintain blood flow.
