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.

    I’ve heard this before and looked it up, but I found this article from the NIH that contradicts what you’re saying.

    Defibrillators are devices that send an electric pulse or shock to the heart to restore a normal heartbeat. They are used to prevent or correct an arrhythmia, an uneven heartbeat that is too slow or too fast. If the heart suddenly stops, defibrillators can also help it beat again.

      There are certain devices that do do that, but it’s not a defibrillator. A defibrillator will stop/prevent an arrhythmia by stopping the heart, and letting it restart on its own (hoping that it goes to a normal rhythm), and delivering further shocks if it gets back into one.

      The device you’re looking for to help a heart beat again would be a pacer, or a pacemaker, which will shock the heart to force it to pump, and restore rhythm that way. They’re commonly used for conditions like heart failure, if the heartbeat generation systems/internal pacemaker can’t generate a heartbeat quickly enough to sustain life.
