1. Explain the step-by-step procedure of performing CPR

on an adult victim.

Answer: The step-by-step procedure for performing CPR

on an adult victim includes checking the scene for safety,

assessing the victim's responsiveness, calling for

emergency medical assistance, performing chest

compressions, giving rescue breaths, and using an AED if

available. This sequence ensures the best chances of

initiating effective CPR and increasing the chances of

survival.

2. What is the purpose of chest compressions in CPR?

Answer: Chest compressions are a critical component of

CPR as they help to circulate blood throughout the body.

By compressing the chest, blood is pushed out of the heart

and circulated to vital organs, including the brain, thereby

maintaining oxygen supply and increasing the chances of

survival.

3. Why is it important to use an AED during CPR? Explain

its role and benefits.

Answer: Automatic External Defibrillators (AEDs) play a

crucial role in CPR by delivering an electrical shock to the

heart in case of a cardiac arrest due to a specific type of

abnormal heart rhythm called ventricular fibrillation. AEDs

can analyze the heart rhythm and provide an electric shock

to restore a normal rhythm, which significantly improves

the chances of survival.
