  1. What rhythm is most commonly treated by an AED shock?

    Answer: Ventricular fibrillation

    AEDs shock ventricular fibrillation and pulseless ventricular tachycardia, which are 'shockable' rhythms.

  2. If an AED advises 'no shock,' what should you do?

    Answer: Resume CPR immediately

    A 'no shock advised' message means you should continue CPR, beginning with compressions.

  3. Why should rescuers switch compressors about every 2 minutes?

    Answer: Fatigue reduces compression quality over time

    Compressor fatigue degrades depth and rate, so switching every 2 minutes maintains quality.

  4. What is 'hands-only CPR'?

    Answer: Continuous chest compressions without rescue breaths

    Hands-only CPR uses continuous compressions and is recommended for untrained bystanders of adult cardiac arrest.

  5. What surface is best for performing effective chest compressions?

    Answer: A firm, flat surface

    A firm, flat surface ensures compressions actually compress the heart rather than the bedding.

  6. What is the first thing you should do before starting CPR on an unresponsive adult?

    Answer: Check responsiveness and call for help/911 and an AED

    Confirm unresponsiveness and activate emergency response to get help and an AED en route.

  7. What can happen if compressions are given too shallow?

    Answer: Insufficient blood flow to vital organs

    Shallow compressions fail to circulate enough blood to the brain and heart.
