Eli5: I understand that CPR is given to a person that has no pulse then what is a defibrillator used for.

Often times in TV shows and movies defibrillator is used when someone has a slow or no pulse but isn’t that wrong? Could some explain what the purpose of defibrillator is used for? And do shows and movie even do research before shooting the scene?

CPR manually oxygenates the blood and pushes it through the body so that we can try to stop brain death for as long as we can. Essentially you are mimiking a heart beat through chest thrusts. But the heart is still not beating right, just beating on the chest won’t fix that. Thats where the defibrillator comes in – it shocks the heart in a way that makes it spontaneously beat again.
