I am glad it worked out but dude is going to get charged with homicide someday if he keeps this up and isn't as lucky with the results. And probably illegal practice of medicine even if nobody dies.
It's a damn good thing he's a minor. Otherwise he'd be slapped with Criminal Recklessness. No amount of Good Samaritan laws can weasel your way out of using a generator as a makeshift defibrillator. Were I him, I'd get used to the unlicensed clinic.
Dude’s hands were burned, he didn’t even treat those, and the old man probably had some too! They didn’t even expose the man’s chest when doing the makeshift defibrillation… sigh I guess I just have to deal with it…
