No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here. This includes using AI responses and summaries.

If you have a stroke or stop breathing does it keep beating even if the rest of you is gone?

A cold, monotone voice can be heard: "this person has expired. Please contact the authorities."

I happen to have some experience with this, as I used to teach anatomy at university. Many of the corpses that we used, contained metal knees, and other improvements, you can, for instance, clearly see where open heart surgery was used to improve the heart. Now, all these corpses have been soaked in alcohol and formaldehyde to conserve them, so they are obviously dead. A few times however, the olde pumpe may start beating again, if it has artificial components. We tutors laughed our toupees off, as students would get the shock of their lives, when the corpses would sit up, or even chase them across the room!

That would completely traumatize me but I also want to see it myself

Most countries use brain death as the deciding factor.
Meaning you body can be held alive artificially, but if the brain isn't working, you are dead, and there is no chance of coming back.
Of course if the heart hasn't been beating for 5 minutes and you are not kept artificially alive, you are probably considered dead too.

Depends on how it's meant to work. If it amplifies the actual heart's movement, it might not do much. They usually have a power supply, which will make it keep doing what it does.

So, if it's a 100% artificial heart, it will do what it does. If it's there to force the heart to beat without the heart's natural movements, it will keep force it to beat the same as before, same as if you pass electricity through any muscle.

I would imagine that it would. The alternative is that it would not, which would mean that it would need some sensor to determine that you were no longer alive, at which point it would stop working. There's no real point for it to have a feature to stop working. It's probably better for it to be seen as 'creepy' by continuing to work inside of a dead body than for it to constantly be checking to see if you're alive, since the surgery to change the battery is probably pretty invasive, so they want to do it only every so many years, to maximise its efficiency. Also, false positives (negatives?) would be problematic. You'd just want it to keep working regardless.

EMTs probably have a way to shut it down, though. It's probably impossible or really difficult to do it accidentally, but I'm sure there's a way. Good question for an EMT if you happen to meet one. They aren't squeamish. It's just a matter if they feel like talking to you or not, I suppose.

This isn't what you asked exactly, but I know they can externally disable a pacemaker once the patient is determined to be deceased so it will stop trying to shock the heart back. Otherwise it will continue to try to save the person.

Your body is alive but your brain is dead and that makes Jesus sad.

But that’s fifty percent of the population.
