Why YSK: TV has lied to you. If a cardiac arrest happens and you have an AED defibrillator at hand you might still need to do chest compressions.

1. When you open up the AED there will be instructions on how to apply the electrodes as well as any other procedure needed to get started.
2. The machine will first analyze the heart's rhythm to find out if a shock can restore the heart.
3. If the machine doesn't find anything it will instruct you to perform CPR. After a while it will then instruct you to stand by as it does another analysis.
4. It will once again either deliver a shock or instruct you to go back to CPR. Do this routine indefinitely until medical services has arrived. You will be tired. Switch out with another person if there are other people who can help.
5. Some AED's are automatic and will warn you to stand back and deliver a shock. Others will need you to press a button to deliver the shock yourself. Make sure not to touch the person as the machine delivers the shock.

Why YSK:

If you're planning to get an extinguisher for your home you need to know that not all extinguishers can put out all types of fire. There are many intricate details if you're interested but for the most part, a dry powder extinguisher can put out many types of fires at the cost of being incredibly messy. On the other hand, a carbon dioxide extinguisher is perfect for electronic fires and doesn't require much clean up. Make sure to get an extinguisher for your needs. Maybe consider getting multiple extinguishers.

As an addendum: If you use a fire extinguisher even just a little you need to either discard it or refill it depending on type. Never put the extinguisher back as is.
