First Aid is the difference between you doing something and doing nothing; what you choose to do could save someone’s life. Even if you are fearful that your knowledge or abilities aren’t 100 percent, it’s still doing something to try and save a life.
The American Heart Association recommends that everyone — untrained bystanders and medical personnel alike — begin CPR with chest compressions.
An AED is an electronic device that analyzes the heart rhythm and if necessary delivers an electric shock. The purpose of this shock is to correct one of the abnormal electrical disturbances. Both CPR and AED can help save a life
