@Robby:
CPR does exactly that all the time.
the effectiveness of CPR is hugely exaggerated in most of the media sadly…of course it's still used because ,hell,no reason not to try,but the percentage of times CPR actually does something is kinda low,and only goes lower the more you wait from the time everything "stopped".
with the amount of time hisoka lied dead on the ground,right now he would at least have severe brain damage..it is pretty much the same problem i had with a certain part of assassination classroom and the revival of a certain character
of course this being a manga with superhumans it doesn't need to be scientifically accurate,but still a revival this late after death feels off
@sanji''s_dad:
People can get heart transplants as well which means they have no heart while it's being removed also people have been brought back to life after dying from extreme cold or people who have dead from heart attacks have been brought back to life with electric shocks as well.
the focus is oxygen,not the heart
the heart is just a pump,it makes your blood flow,what your body really needs is what it's inside the blood,mainly the oxygen when talking about such short period of times
during operation to the heart you are still attached to a pump that makes heart's work for it,the oxygen is either provided by a machine or the lungs themselves,depending on the conditions of the patient.
for the heart attacks and defibrillator shots,it's a common misconception for what i know.
just analyze the name, "de-fibrillator"..a fibrillation si an irregular heart beat,"de-" means to stop,or eliminate…basically what a defibrillator does is "restart" your heart if it is CURRENTLY STOPPING,basically if it's during the fibrillation that precedes the complete cease of its functions..it does so by "shocking" the heart to make it stop for a fraction,hoping that it will start beating regularly afterwards..it's the "turn it off and on again" you do with your computer when you don't know what else to do.
about the whole extreme cold thing i don't know much thou@Watch-man:
Sometimes people get brought back to life with CPR after more than 10 or very rarely even far more minutes.
source on that?
10 minutes without oxygen in your brain seems like an awfully long time
