a.
true
b.
false

The given statement "An AED should only be used if a person is too tired to continue with chest compressions" is false.

Option B

Explanation:

Most people think that they are very tired after applying the compress for 2-3 minutes. When the compressor is tired, it tends to compress more slowly. For this reason, rescuers are advised to do compressions in every 2 min to prevent fatigue and optimise the compressions quality. This should only be done if the person does not show signs of life or is dead, does not respond and breathes normally.

For example, consider you come across the victim in a narrow place and you have two helpers: Rescuer 2 arrives with the AED (automated external defibrillator) and puts it on the opposite side from Rescuer 1, who does chest compressions. Rescuer 2 turns on the AED and fixes the electrodes to the victim's chest, connecting wires to the AED if necessary. Rescuer 1 can continue CPR (Cardiopulmonary resuscitation) by placing electrodes until the victim's heart rate has been analysed.
