  1. What is the recommended compression-to-ventilation ratio for one-rescuer adult CPR?

    Answer: 30:2

    Single-rescuer adult CPR uses 30 compressions followed by 2 breaths.

  2. 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.

  3. What is the correct compression rate for adult CPR?

    Answer: 100 to 120 per minute

    The recommended rate is 100 to 120 compressions per minute.

  4. Where should your hands be placed for adult chest compressions?

    Answer: Center of the chest on the lower half of the breastbone

    Place the heel of your hand on the lower half of the sternum in the center of the chest.

  5. Why is allowing full chest recoil between compressions important?

    Answer: It lets the heart refill with blood

    Full recoil allows the heart to refill, improving blood flow with each compression.

  6. What should you do if you are untrained or unwilling to give rescue breaths?

    Answer: Provide hands-only (compression-only) CPR

    Hands-only CPR is recommended for untrained bystanders and is effective for sudden adult cardiac arrest.

  7. How long should you take to deliver each rescue breath?

    Answer: About 1 second, enough to see the chest rise

    Each breath should last about 1 second and produce visible chest rise.
