Plastic bag method that might actually be great

[BlissfulEnigma]

So, not long ago I posted about a potential method which involves hyperventilating followed by taping your mouth and nose shut. The hyperventilation part SHOULD lower CO2 enough to experience a hypoxic blackout, but I realized that 1. The tape might move around and let air in due to unconscious conclusions, and 2. I don't have strong tape around anyways. But what's it you used a plastic bag instead? So you hyperventilate until your CO2 levels are extremely low, then you place the bag over your head and tighten it as much as possible. It might be bit more complex than that, but how would this not be effective assuming the bag is airtight and for the most part airless?

always poses the risk of brain damage if found, and it's hard to guarantee it would kill

I don't want to rain on your parade, but this is almost certainly not going to work. Passing out from hyperventilation, or holding your breath for a long time, only lasts for a few seconds. You will most certainly regain consciousness and begin to struggle - especially if you use a plastic bag. Once respiration resumes, the bag is going to fill with slowly rising levels of co2, which in turn is going to activate your body's hypercapnic response. Meaning you will tear the bag off of your head unless you have an extreme amount of willpower.

You would be better off introducing some type of asphyxiant to the plastic bag, which will induce unconsciousness and therefore bypass the hypercapnia.

Well I'd appreciate if you could elaborate. When you make the claim that unconsciousness lasts just a few seconds, can you explain how that happens? Because to me it wouldn't make sense for your oxygen to reach such low levels and then suddenly rise back up after a "few seconds". And again, the bag is ideally so tight that there is a negligible amount of air that you could theoretically breathe in. Maybe you're just criticizing the use of hyperventilation alone to cause unconsciousness , but what I'm saying is that if you also utilize a tight plastic bag around your head (AND very crucially, holding your breath as long as you can as soon the hyperventilation is done), then I don't see why you go from consciousness to unconscious and THEN back to consciousness.


Edit: looking back, I really should've added that it is CRUCIAL that right after you hyperventilate, you must exhale all the air out (or as much as possible) and HOLD it like that while securing/tightening the bag over your head. Obviously if you just hyperventilate and tighten a bag over your head, you will breathe in more oxygen as a result and I would not trust that.

If you do some searches on the forum, you will find a wealth of information about people who have tried this.

Unconsciousness is short lived because you have approx. 5 liters of oxygenated blood circulating throughout your body. It would take approximately 4 minutes, assuming you have no additional oxygen supply, to be in a state where you lose consciousness. As long as your heart is still beating, your brain is still getting oxygen.

Free divers hyperventilate and are able to hold their breath for a very long time. Typically, they only lose consciousness after several minutes and due to the depressurization of the lungs, ie., going from deep water to shallow water. If they simply passed out immediately due to not having the urge to breathe, they would die.

You can certainly do what you feel is best, just trying to offer my 2 cents. YMMV

Umm a normal person can hold their breath for 4 minutes with hyperventilation (or pass out before then, which is what you want). And shallow water blackout specifically does not depend on pressure change that compresses and decompresses the lungs. All kinds of people have died from SWB in accidental situations, so I don't see your point holding up. But if there are threads you can point me to that have tried to do something similar to what I'm suggesting, then I'm more than willing to look into those sources. I appreciate your comments though, so thank you for that. I'm gonna CTB in the next few days, so i need something that is quick and painless (i would use inert gas, but i don't have access to it)

You can hold your breath for 4 minutes after hyperventilating? That's pretty extraordinary and not something I would think most people could do.

I mean, it kind of doesn't make sense unless I'm misunderstanding you. If you are able to do that, did you pass out? Obviously you are still here, which would indicate you passed out and resumed respiration. All of that oxygenated blood is then going to convert to oxygen and carbon, or, co2, filling the bag with such.

We'll have to agree to disagree about swb. I was not saying that it relies solely on the depressurization of the lungs. It's a combination of factors and the initial pressure the lungs undergo at depth is one of several physiological components that enables the diver to even hold their breath long enough to cause hypoxia.
There have been many discussions here by people who have entertained using hyperventilation as a way to ctb - mostly in conjunction with drowning. To my knowledge, nobody has been successful with this.

I was simply offering my opinion based on what I've read here, which, as stated, been discussed from time to time. You certainly have the right to do what you feel is best.

I do hope you find the peace you are after, whatever that may be.
