Might be leaning toward asphyxiation 🤷‍♂️

What are your thoughts/opinions on helium inhalation as a means to catch the bus? Sound viable or no?

 

[imontheloose]

Definitely viable. Quite quick and painless in theory. You'll lose consciousness before you really process what's happening. Pretty sure you can lose consciousness within a minute or two: helium will rapidly replace oxygen. The body doesn't get panicked or scared from the lack of oxygen because them signals are specifically designed for CO2 buildup.

Just make sure your helium is pure (not mixed with oxygen) and you have a sealed environment to prevent oxygen from mixing with the helium, and ideally your arms restrained gently via a seatbelt or something. As long as you have a decently sized tank with a steady flow, the job'll be done within a few minutes and death will follow shortly after.

Thanks for the input . I'm assuming I'll need to buy a face mask system to attach to the helium tank. Is there anything else I should know/do once I've donned the mask and attached it's feed to the helium tank, or do I just loosen the tank's valve and sit back after that?

You're welcome!

A face mask or a hood/bag system connected to the tank is the core setup. The mask/bag would have to be securely fitted to prevent any air leakage. A simple plastic bag with a tight seal around the neck combined with a tube running from the helium tank is the common, theoretical setup and there's plenty suicides from it. See below.



A mask with straps will work too, obviously. If anything, it's a nice security of it being airtight. Your only worry should be that as hypoxia sets in, you might instinctively try remove the mask due to SI / fleeting panic, even though you don't feel suffocation per se. Maybe a soft restraint like velcro straps on a bed or chair would be fine without discomfort. We more just want to ensure the process isn't interrupted more than anything else. If you're committed and calm, this really shouldn't be an issue, but it's worth a thought.

Opening the valve onto a nice, steady flow is key. You want a flow rate high enough to fill the mask quickly and maintain a pure helium environment, something like 15-20L/min from any pure helium tank will do the job. Standard tanks are about 10 cubic feet I believe; more than enough gas to complete the process, even after unconsciousness sets in.

Like we discussed before, make sure it's 100% helium. You could maybe speed up the process by taking a few deep breaths of good ol' air before starting then exhaling fully to empty the lungs of oxygen, but this doesn't matter all too much; you may panic doing so as well. Within about 5 minutes, you'll likely be dead, so your tank needs to be flowing for at least that long to ensure the process doesn't get interrupted.

I'm trying to give just some food for thought here on ideas, but please let me know if you want anything further explained.

N2 type nitrogen is cheaper, the air everywhere on earth is 78% nitrogen and 21% oxygen and 1% of other gases, but instead of 78% nitrogen, you want to add 22% more nitrogen by volume in the 78% so it's 100% N2 nitrogen, N2 nitrogen is inert meaning it keeps the alveoli in the lungs inflated so that you won't get hypercapnia from collapsed lungs/collapsed alveoli and pnemothorax, the N2 nitrogen is actually good for the lungs, it actually is needed for life as 100% oxygen will be absorbed too quickly in the lung's that you will get absorption atelectasis without nitrogen, nitrogen doesn't get absorbed meaning it keeps your lungs and alveoli open to breathe again, all it does in 100% form is displace oxygen WITHOUT causing collapsed lungs/collapsed alveoli and pnemothorax.

This seems misinformed, honestly. Only true benefit is that nitrogen may be cheaper or more available for someone. Neither gas causes alveolar collapse or pneumothorax when inhaled through a mask/bag; lung inflation is maintained by breathing mechanics, not the actual gas. Both gases will achieve unconsciousness and death within minutes without distress. Nitrogen keeping alveoli inflated isn't unique to nitrogen, it's true for any gas inhaled at standard pressure.

Your claim that nitrogen is actually good for the lungs is just a strange statement. How is it good? It's fundamentally neutral and is just kinda there as far as the body cares. The lack of hypercapnia is true for both gases because neither introduces CO2 nor prevents its exhalation initially. Only valid difference is helium is much lighter than nitrogen so helium will disperse quicker in an open environment or leak faster from an unsealed mask, but that means nothing: we are talking about a controlled setup here.

It's a matter of convenience. Some find it easier to purchase a helium tank as far as explaining goes compared to nitrogen, whereas others can just take the cheaper option of nitrogen and be on their way.

I said it's cheaper but it's harder to get because it's not like you can search up where pure nitrogen is.

Perhaps, but your other claims are inaccurate.

Yeah I don't know what I am saying, my bad.

It's okay, love. Cuddles! No need to feel bad.

I think that's all the info I'll need to ensure I get the job done properly Thank you so much for all your help
