Co2 Asphyxiation Questions

[Driftwoodau]

That's my planned cbt method due to the massive accessibility of Carbon Dioxide, though I have some questions reguarding it.

My plan:
Pitch a small tent in a secluded bit of forest and bring a 6kg/1000L CO2 gas cylinder in with me. After zipping it up, open the tank to fill the tent and just chilling out in there until hypoxia or hypercapnia takes me away
This is the one I will get...or something like it:

CO2 Gas Cylinders 6kg (full)

Our 6Kg gas bottles come full of CO2. With a cylinder shut off valve this little tank can dispense over 900 litres of beer. Up to 450L of carbonating and dispensing if used for homebrewing purposes. Australian Standard Approved.

If they ask what it's for, I can simply say it's for a fathers pub
Tent would be a small dome tent

So would that work? Is there anything you would improve or any suggestions at all.
I'm pretty new here, so any advice would be hugely appreciated
Cheers all <3

CO2 is what your brain uses to know when to breathe. Inhaling CO2 signals you need to breathe more which leads to panic. You will freak out and tear the zipper open to get air. This is exact same as putting a bag over your head and will not work.

CO2 wouldn't work but CO would.

Will it work? Yes. Will you suffer? Greatly. You see, as Forveleth mentioned, our bodies monitor CO2 levels in the blood, not O2 levels. That's why Exit bag or other inert gas methods use not only oxygen free atmosphere but also CO2 free one. For example, breathing pure nitrogen, you can freely expel CO2 from your body so no "i'm suffocating" alarm is triggered in your brain. You fall unconscious pretty quickly from lack of oxygen and die moments later. If you do that in pure CO2 atmosphere, CO2 from your blood has nowhere to go, starts building up in your bloodstream, triggering all the alarms and fight responses in your brain and even unconscious, your body will fight like hell to prevent suffocation, probably demolishing everything around you.

I think I was dumb and assumed CO and CO2 were the same...

My plan:
Pitch a small tent in a secluded bit of forest and bring a 6kg/1000L CO2 gas cylinder in with me.

6 kg of CO₂ expand to approximately 3000 L at atmospheric pressure. 1000 L is the estimated volume of beer that could be dispensed with the given amount of CO₂, which has zero importance in the context of asphyxiation.

After zipping it up, open the tank to fill the tent and just chilling out in there until hypoxia or hypercapnia takes me away

Chilling out is hardly possible with this gas. You'd experience shortness of breath and have strong respiratory stimulation.

So would that work? Is there anything you would improve or any suggestions at all.

For relatively quick sedation (approximately within 1 minute), you'd need a CO₂ concentration of at least 17%, and for sedation in about half a minute - 30% or more. Inhaling CO₂ at concentrations that are insufficient for achieving narcosis in 1-minute period could be very unpleasant. In case if you're an anxious person (like many forum users here), CO₂ can boost your anxiety/fear greatly. This effect can be mitigated by taking alprazolam.

I think I was dumb and assumed CO and CO2 were the same...

They're not the same. Both can be used for CTB, but CO₂ may cause some significant discomfort which you'd have to bear before narcosis is achieved. Shortly before LOC, you can see some colorful hallucinations.
