I wish to explore a method and get the community's take on it. I have a method and then a 2ndary back up method.

Method 1:
  1. Sturdy plastic bag around head
  2. Insert tube into the bag
  3. Seal the bag up with drawstring & duck tape
  4. Put ANOTHER (a 2nd bag) over my head and seal that one with duck tape
  5. Turn on helium tank
    1. The tank I bought is only 106L - https://shopbvv.com/products/0-95l-130g-hp-helium?variant=41364077314144. The valve I bought with it is just a normal valve with no readings/guages. Do I turn it like 2-3 turns only to have a steady stream? Or Do I crank open all the way?
  6. Fall unconsious and suffocate/aphyxiate

The problem with method 1 is I am afraid my tank is not enough. I read the sticked helium thread and it suggested 600L.... That's a lot and expensive...!

Therefore, I have a 2nd backup method.

Method 2 (backup):
  1. Sturdy plastic bag around head
  2. nsert tube into the bag
  3. Seal the bag up with drawstring & duck tape
  4. Put a noose around my neck
  5. FSH myself while standing on a flimsy stool
  6. Turn on the helium tank
  7. Fall unconsious and let hanging finish the job

I would love feedback and thoughts on my methods, please. What flaws do you see? What could go wrong? Chances of success? Which method has better chance of success?

My main goal is to work with what helium I have. I want to go as peaceful and painless as possible.

Thank you!

Not sure what exactly you want to achieve with helium. A correct execution of FSH should produce unconsciousness in <20 s, so if you expect it working as intended, then maintaining helium asphyxiation for several minutes doesn't look necessary. If your windpipe is blocked, you won't even be able to inhale the gas anymore, and if your arteries are properly blocked, it shouldn't really matter how much oxygen is present in the blood below the neck, since it physically can't reach the brain in amounts necessary to keep you aware of the situation. If the only goal is to minimize discomfort before loss of consciousness, a few deep breaths of helium should be enough for that. The sedation likely won't be complete at the moment when the FSH begins, because the loss of bodily control happens before LOC, but partial sedation is better than nothing, and the duration of discomfort (if it's perceived) should be significantly shortened.

If you assume that your FSH can be done improperly and you consider helium asphyxiation as an additional method that ensures death with minimum discomfort, then planning could be different. In case of thinking this way, you could prepare for the worst-case scenario when FSH doesn't work at all and helium asphyxiation plays the role of the sole working method.

It's precisely as you assumed in the 1dt paragraph. I want to minimize any effects I feel from FSH by inducing unconsciousness via helium. But I am just scared 106 liters of helium is not enough to induce loss of consciousness. And that is what I really want to check.

Idk. But I do know that nitrogen is cheaper than helium… is there any reason why you can't just wait until you have enough $$$ for a larger tank of inert gas? Or pay with credit… it's not like you'll ever have to pay it off, you know?

106 liters should be enough for passing out multiple times, so this amount could be used for testing and sedation before CTB. As little as 2 inhalations of helium filling the vital capacity of the lungs or nearly so should be enough for inducing unconsciousness in many people. 3 or more such deep inhalations would likely work for almost everyone.

For example, this girl started fainting after 5 breaths, but since there is a time lag between each inhalation and its effect on consciousness (a few seconds is needed for the blood to move from the lungs to the brain), she could have passed out without making the last two breaths as well, although the average volume of gas per a single inhalation didn't look nearly as big as the vital capacity:

I've tried to describe some theoretical and practical aspects of sedation via gas asphyxiation before drowning in this thread. Many of them are applicable to sedation before FSH.

Discretion. It's harder to hide a giant tank. The tank I got is only 12" x 3".
And the nitrogen wasn't that much cheaper unfortunately.
But as another response said, a few breaths of helium should be enough to sedate me and then FSH will finish the job. Hopefully this is true.

Sedation is just the brisge - FSH is the main method.

Thank you!

I have everything I need to CTB. Just waiting for the right time.

1. Polyurethane bag with draw string - which I'll sealing up with duck tape
2. Rope
3. Sturdy trash bag as a 2nd seal
4. The pain/suffering relief: 99.99% pure helium - 106 liters/19
5. Small stool
6. Tubes
7. Last but not least, the determination

If I wanted to CTB via FSH, I'd use nitrous oxide instead of helium because of the additional analgesic effect and perform inhalations from balloons through the mouth instead of using a plastic bag over the head to ensure that no air is mixed with the inhaled asphyxiant gas.

I've seen your posts about that… is nitrous going to be your method? I'm becoming increasingly curious about it.

I don't think nitrous oxide is that readily available or easy to get. Is it ?

It depends on where you live. Food-grade nitrous oxide is used for making whipped cream and can be legally purchased by individuals in many countries. In some locations, cartridges or canisters with this gas are sold mainly via online market and rarely can be seen in offline shops; in some other locations, they can relatively often be found in offline shops too.

I easily purchased a few packs of 8g chargers together with a dispenser, which provides a handy way to release the gas from such chargers. A single pack of 10 x 8g chargers (each giving about 4 L of gas at atmospheric pressure) costs approximately 6 USD and a cheap dispenser costs 20 - 25 USD here. These prices look fair to me.

Wealthy people could consider the possibility to obtain xenon, which is a stronger anesthetic than nitrous oxide, but insanely expensive.

Say I am able to get my hands on nitrous oxide, is it still the same concept?

Disperse the gas in to bag over my head?

Helium should be better than nitrous oxide for the purposes of displacing air from a bag when it's turned upside down, because helium is much lighter than air and easily builds up at the top, whereas nitrous oxide is heavier than air and goes downwards. I think, the easiest way to produce profound hypoxemia before FSH would be making 3 - 5 deep breaths of the gas from 1 - 2 balloons. A plastic bag over the head can also work, but this method is technically more difficult to implement, and I don't see significant benefits from using it.

Although the onset of analgesia from nitrous may happen in about 30 seconds, in order to achieve a really good degree of analgesia, 2 - 3 minutes of inhalation of Nâ‚‚O with air or oxygen may be needed prior to the planned gas asphyxiation followed by FSH. During the preliminary stage, adding medical oxygen is probably better than adding air, because air doesn't completely prevent hypoxia due to insufficient percent of oxygen in the resulting mixture. Hypoxia may incapacitate the person and introduce the need in periods of recovery. In some people, multiple episodes of hypoxia within a short time interval may provoke nausea.

I am curious about this method because they do sell those cartridges in my country, but I might be dumb and I don't understand a thing. Don't you need to in FSH to make sure you're suspended by kicking the stool/chair? Or will your body fall from the chair when it loses consciousness? it also kinda works with PH but feels more risky

I plan on standing on a very small stool and carefully at the height where I'll be tiptoeing on the stool.

Once I pass out from the helium, I'd just fall over and out of the support of the stool.

However, I am kinda considering death by carbon monoxide via charcoal burning right now ..... Seems easier and less painful. Sounds like you just drift off to sleep?

Some people kick a chair, others just go off a ledge. Holding the rope by hands is also common, f.e., see
Or will your body fall from the chair when it loses consciousness?
Loss of consciousness from gas asphyxiation happens after loss of body control, which happens after the sense of impending fainting occurs. So a possible plan could be grabbing the rope and going off the ledge (or kicking the chair) right after noticing the sense of impending fainting and then reducing the pressure on the neck by holding the rope for as long as this remains doable.

Oh, thanks! I get it now. So, you have a short amount of time to react based on a feeling before you lose consciousness. I probably had my doubts because I had never lost consciousness before
