inert gas pain: debate

[Old Friend]

"Thrashing around" is not unusual for any body nearing death. It doesn't suggest pain.

Also, you cannot be "poisoned" by inert gas.

With respect, I feel you simply don't know enough about the subject matter.

 

[Kasumi]

dont you think it's possible they notice but they cant act becaise they're too impaired?

bodies poisoned by inert gas have been known to thrash around

Yes and it's common to experience seizures through chemical methods f.e. cardiac switch method, but they aren't a problem when you properly sedate yourself into unconsciousness.

Muscle movement close to or during death isn't uncommon and it doesn't mean you feel it as those things are an automatic reaction.

 

[doneforlife]

You totally pinpointed what I am thinking and failed to explicate. I think exactly this is the reason why people always start threads with the same questions like "is SN really peaceful" or something like that because they wish for a swift death and want reassurance, whereas the reality is that most deaths, natural and unnatural ones, are violent. The thing is this case you ultimately never know whats inside the box so to speak before you open it.



I am with you and it's my position at this point of research. And yes, of course, the initial process of breathing N2 is peaceful because there is no hypercapnic reflex induced by CO2. I'm more concerned of what happens when I am unconscious. Will I really don't experience anything? Or will I experience my brain shutting down, my heart stopping and so on while I am not able to move? A lot of inert deaths come with pulmonary edema for instance which is pretty bad. But in theory, your higher brain functions should have ceased before the heart stopped.


Of course they have an agenda, but the same goes for the right to die scene that downplays the drawbacks of the methods and often claim it's just like falling asleep while the reality is different. Here are some collected cases where euthanasia with drugs didn't go as planned. Yes, it's a pro life site, but that doesn't change the facts of the collected cases:

11. Not a rapid or peaceful death

www.australiancarealliance.org.au

So not even N and similar drugs guarantee a peaceful death. And you also have to keep in mind that most of the subjects were probably old and terminally ill, so it migth even be worse for younger persons.

What about anesthesia? I am not talking about an overdose. People get cut , operated , stitched back all the while feeling nothing. So , use anesthesia and then remove a vital organ , so that one never gets back consciousness. Ofcourse this will not come under DIY and one can't team up with docs . Just speaking from a pain vs painless perspective. Will this also be painful ?

It's simple - the more expensive the method, the less pain it will be. It is also about accessibility. If it's hard to get, then it's easy and painless for CTB.

I've already spent $700 on my nitrogen/Scuba equipment and will probably need to spend another $100 (expensive). N is impossible to obtain (accessibility). Inert gas and N are both quick and painless.

Why do you think that SCUBA will be less painful than the exit bag? Overall I can see no correlation between the costs of a method and their painfulness.

I think Scuba and exit bag are equally painless. I just don't believe I can put a bag over my head like that to do it. Scuba is a mask you put on. I can do that.

Guns are also expensive; and if done right, quick and painless. Cheap methods (jumping, jumping in front of a train, poisoning, etc.) are a fraction of the price of guns and SCUBA. Even SN comes with discomfort and no guarantee it will work...but is relatively cheap.

Being unconscious generally means you'll be unable to feel anything, ultimately we cannot ask those who went unconscious if they experienced any pain since they don't remember anything.
But consider people that throw up while being unconscious and then suffocate from that.
If they would in any way be able to realise they were suffocating they would wake up or at least unconsciously move / cramp to clear up the airways.
Which I'm sure is pretty much exactly what happens when you're just asleep or lightly sedated, but if you're deeply unconscious like due to strong sedatives or severe lack of oxygen then no you won't react anymore which suggests that your body doesn't even notice.

There should be no difference, so long as no oxygen gets in. The exit bag is cheaper but it's easier to get wrong. We've had a few on here who've unsuccessfully attempted with an exit bag. They simply didn't pass out as they were still getting oxygen. The bag is nearly always the culprit. EEBD masks are also becoming more popular with this method.

it's unlikely from all observations and experiences but since we cant ask anyone that went unconscious with inert gas you cannot be 100% sure.
I mean if you're worried about it then don't do it, its as easy as that imo.
If you don't 100% want to die then you shouldnt.

inert gas does not damage the body in any way, its not a poison.

Inert literally means chemically inactive. A poison is an active chemical. What you say is a contradiction.

 

[Andrew10]

No need to debate

I am a very lucky survivor of this method, I can assure you that it was painless and I was lucky that the consequences were a headache for 3 days and that my vision was permanently damaged I felt like I was a robot and they turned me off temporarily I felt absolutely no pain. I just didn't do the method correctly and out of fear I did self sabotage, I was lucky because I probably could have ended up being a vegetable. But after going through this experience I can assure you that it is completely painless

It scared me a little but I'm gaining courage to try again and I know I'll make it, there's just a strange feeling that stops me but I know I'll defeat it

Can someone with medical knowledge walk me through how CO2 might build up with SCUBA?

Do you guys think vomiting into the scuba mask could cause you to wake up?

 

[Old Friend]

No it doesn't.

I'm not quite sure what the deal is with you, honestly. You appear to be on some sort of campaign and show little interest in what others have to say about the matter.

Edit: and now you've edited your post to go on about the hypothetical risk of CO2 build up in equipment used in a hypothetical judicial execution. This is a suicide forum, not a capital punishment forum.

I'm doing some research into unconsciousness and pain and it seems like it is not an straightforward answer.

In a brochure on "Understanding the dying process" it states: "The unconscious person may still feel pain as they did when they were awake. For this reason pain medication will continue to be administered but perhaps by another method such as the subcutaneous route (through a butterfly clip in the stomach, arm or leg). [link]

There simply isn't much medical data on pain and unconsciousness, they did a study on people with brain damages:

"Little is known about pain perception in unconscious patients, says Steven Laureys, a neurologist at the University of Liège in Belgium and the senior author of the new study. As a result, whether to provide drugs is up to individual doctors. Some doctors withhold medications, Laureys says, assuming that these patients are unable to feel pain." [link]

"Now a study finds that the brains of some patients with brain injuries respond to an unpleasant electrical shock much as do the brains of healthy people, suggesting that these patients may feel pain even though they're unable to show it." [link]

They came to the following conclusion: "But the minimally conscious patients exhibited levels and timing of brain activity that were very similar to those in healthy people, the researchers report online this week in The Lancet Neurology. Although PET scans and other neuroimaging tools won't ever reveal what people actually feel, Laureys says the new findings suggest that minimally conscious patients may have a greater capacity to register pain compared with those in a vegetative state--and a greater need for drugs to treat it. The capacity to feel pain may be another factor for patients' families to consider when weighing end-of-life decisions, he adds." [link]

Another article also describes it as likely that unconscious people experience pain: "Given the data, it's likely that unconscious individuals (specifically, people in the minimally conscious state) do experience pain. However, there still isn't enough research being done on pain, at least, not enough to comfortably compare degrees of pain or even detect it in some cases." [link]

A neuroscientist on quora writes the following on the question of pain and anesthesia:

"This is highly debatable, however anesthesia awareness, for example, is a serious concern during medical procedures and is an ongoing point of major research interest.

It is easy to say that, without conscious awareness then "you" do not "feel" pain, and it's most certainly theoretically plausible for the pain-sensing receptors in your body to respond to noxious stimuli and have an effect but never enter your cortex (and thus your consciousness).

One possible effect of anesthesia awareness is that you have no conscious memory of a painful event, but your have symptoms of having experienced a traumatically painful event, such as signs of post-traumatic stress, anxiety, panic, etc.

Actually, now that I've read the wikipedia page for Anesthesia awareness
, I'd suggest checking it out. It's quite good." [link]

Thanks. But this is scary. Is there a way to destroy the pain center in brain . I had heard of a patient who couldn't feel any pain because that part of brain which perceives pain was damaged. Why are researchers not focusing on that for painless exits.

this has nothing to do with nitrogen CTB, and i'm wondering why you posted it?

Your second link is about Terri Schiavo, which US media have been using her as a marketing tool for "don't commit suicide" for years.

If you're unconscious, then you have no perception as to what's going on around you. You're not conscious. Being unconscious is not a dream. Unconscious means you know nothing that's happening around you.

Seems like you are a suicide hotline agent. And that's cool. But just disclose that.

 

[Glandular]

I'm more concerned of what happens when I am unconscious. Will I really don't experience anything? Or will I experience my brain shutting down, my heart stopping and so on while I am not able to move?

Maybe you should look into general anesthesia research then? I don't know if there are differences between being unconscious because of an inert gas or because of some chemicals. I just assume that once you're out you experience nothing.

It scares me too. But note that these studies talk about people with a minimaly conscious state, it doesn't mean that they are fully unconscious. And just because there is an electrical pattern in the brain, it doesn't mean that the pain is experienced:

"Stuart Derbyshire, who studies the connections between neural activity and pain at the University of Birmingham in England, cautions that the brain activation patterns don't necessarily mean the patients actually experienced pain. "We cannot read subjectivity from activation patterns any more than we can read it from changes in breathing, heart rate or blood pressure," he says.

"Patients undergoing procedures with sedation might also activate cortical regions during noxious intervention, but one might hesitate before calling that pain," says Derbyshire." [link]

I'm neither a pro lifer nor an suicide hotline agent, I'm just concerned if, and when yes, what I might experience after falling unconscious. Of course the sources have nothing to do with nitrogen CTB. There aren't any, that's why I did not post one. The first source simply states that at the end of life, unconscious people might experience pain.

If you read the second source carefully, it has nothing to do with Terri Schiavo at all, she is just mentioned two times in the article. The article is about a study with 15 healthy people and 15 in a vegetative state.

The studies I quoted were done with people in a minimally conscious state or a vegetative state, one might argue that being fully unconscious is something different. But I didn't find studies to confirm any of that. In my next post, I specifically pointed out that electrical impulses don't necessarily mean that the person experiences pain.

exit bag or scba/scuba?

Exit bag, I tied a bag around my neck with tape. I didn't see the need for me to use scba/scuba although I think that there is a greater chance that it could go wrong with the bag than with the scba/scuba. But I highly doubt that varying between the bag or the mask will feel anything. In my case I felt absolutely no pain in the process and it could have worked if I hadn't self-sabotaged.

 

[Kasumi]

I mean yall can believe what you want, this thread was answering if N2 is painless and the answer is "as far as we are able to tell, no, generally no, no."
Only because we cannot look into the brains of unconscious people (or people in general) and we cannot ask about what no one remembers, for all we know your consciousness could be teleported to mars where psychic aliens experiment with your consciousness.

If you wanna believe in the little remaining uncertainty go ahead.
If you don't wanna take this method, there's plenty of other options and honestly if you do not want to die cause you're afraid of the possible pain,.. then don't die.
Yk, we're not here because we have to die, we're here because we want to, and if you don't want to then you obviously shouldn't, why do I even have to say that.
Plenty of people find one reason or the other to continue living after all.

All we know for a fact is that people who breathe inert gas and survive don't report about any pain at all.
And that people who pass away generally seem to do so peacefully.

Idk what the talk about CO2 buildup is but it's impossible for CO2 to build up without breathing oxygen.
Additionally you're continously exhaling the CO2 already in your body.
Also regarding pets, usually you fully exhale before taking the first breath to minimize O2 available in your body, you can't tell a pet to do that.
That aside, hypoxia is a bad thing that shouldnt happen to healthy people but it's not painful.
That also aside, I don't think that quote is in any way representative of the general experience, there are plenty of reports of people passing out on accident from breathing helium or other inert gas for whatever the reason, completely without any warning and any signs of hypoxia while still being conscious.

Make of that what you want, I'm leaving as I do believe op's questions were repetedly answered already.

Yes, they suffered. But if you read carefully then you see that they weren't placed in a 100 % nitrogen environment from the start, but the nitrogen was introduced gradually. In this case it is obviously that they experienced hypoxia before falling unconscious. In an oxygen free environment they would pass out before feeling distress. With the inert gas method you breath N2 right from the start.

View attachment 126677
Can someone with medical knowledge walk me through how CO2 might build up with SCUBA?

Do you guys think vomiting into the scuba mask could cause you to wake up?

With SCUBA CO2 cant build up because it is exhaled. And I guess when you are unconscious you won't wake up from vomiting, a lot of OD deaths are because they asphyxiate on their own vomit.

View attachment 126704

Seizures with N2 are likely to happen, the study quoted here is also quoted in the wiki article on inert gas asphyxiation, you should read the quote here. Unfortunately, the participants of the study weren't asked how they felt or if or what they experienced. Throwing up can happen, but it seems to be a rare possibility, I just found it in one article that I read. I also found one case of barotrauma to the lung, this happened because the person didn't use a regulator.

If you want to know what the process of ctb'ing via inert gas looks from the outside, I can only stress to read the two articles posted here. As far as I know these are the only recorded observations of humans using the inert gas method. All the bodily changes are described an one can form their own picture if it is peaceful. From the outside it doesn't look that bad. In another paper I can't remember, one guy even made a medical experiment out of himself and recorded himself and an oxymeter and stated that he wanted the data released. But they authorities of course didn't do it.

There was a video somewhere of a pig eating from a trough with pure nitrogen pumping into it. The pig passes out in seconds, wakes back up and goes to the same trough. If nitrogen was painful it wouldn't return to the trough without hesitation.

The fact that you do pass out readily and your brain is starved of the fuel it needs to function would indicate to me you'd not feel pain or at least as much as any other way of dying from the brain being hypoxic which arguably is the most common form of death.
