Need help with hyperventilation method

[n6htzd08cdtfght]

I've read that by hyperventilating, the CO2 levels in the system can be reduced to a point where there is no longer an urge to breath. When this state is achieved, the person can simply hold their breath until they pass out, and without CO2 in the system, the body does not automatically start to breathe and death occurs.

I found lots of resources for free-divers that explained the dangers of using this method, but I cannot find a specific method detailing the process itself. I have tried the wim-hof method, but this still results in a urge to breath.

Does anyone know of a specific method to do this and any thoughts on its effectiveness? thanks.

I want to learn hyperventilating too, but I only found out that you either have to shallow but quickly breathe or breathe deeply and quickly.
My last post didn't get any replies either and my question wasn't even that dumb, it wasn't even a question..

I have not personally heard of this method, but if this refers to free-divers specifically discussing this, it most likely has to do with the body reacting to the change in pressure when returning from the dive and should not be applied to just breathing regularly.

CO2 is constantly produced by your cells, so once you stop overbreathing, its level in the bloodstream will rise back to normal. In case if breathing is stopped completely, the CO2 level will eventually rise further to the point when hypercapnia typically occurs. If you lose consciousness due to either lack of oxygen or excess of carbon dioxide combined with lack of oxygen, breathing will likely be resumed automatically.

Deep inhales and exhales performed at the rate of 1 full cycle (inhale + exhale) per 1.5 - 2 seconds seems to work the best for me. A deep exhale removes a large volume of residual CO2 in the lungs, and a deep inhale dilutes the remaining CO2 with a large proportion of air, so that the partial pressure of CO2 should decrease significantly with each iteration and this should produce efficient removal of CO2 from the bloodstream.

In order to minimize the CO2 level in the bloodstream, it may be useful to stay as relaxed as possible, because any extra physical effort can increase the rate at which new CO2 is produced by the body, partially negating the efforts at reducing the CO2 level.

It may take 2 - 3 minutes to achieve significant hypocapnia which manifests itself by strong tingling sensations in the limbs and lightheadedness. I almost always get headaches in the profound hypocapnic state, so I don't find it a comfortable way of delaying the urge to breathe for very long periods that would suffice for fainting due to running out of oxygen during breath holding. I only use hyperventilation when I need to postpone the urge to breathe for time intervals of up to 2 - 2.5 minutes, while loss of consciousness can be much more easily and comfortably achieved via inhaling simple asphyxiants.

Thank you ^_^
I think you can pass out from both too much / too less oxygen and too much / too less carbon dioxide, isn't it? If I'm understanding everything correctly, if you hold your breath and walk around, your body converts the oxygen, that is in your lungs into carbon dioxide. So if you hold your breath too long you eventually pass out from too much co2 and too less oxygen.
I am trying to understand it, because I like diving and I want to make myself faint / feel dizzy without drugs.

You can't get too much oxygen by overbreathing with plain air at the usual atmospheric pressure. Too low CO2 level leads to constriction of the cerebral blood vessels, reducing blood flow to the brain (this is the cause of lightheadedness), but this effect is quickly reversible as CO2 builds up back to normal levels after you stop hyperventilating. Too high CO2 levels cause narcosis, but if you're conscious, you'd likely feel the urge to breathe before the narcotic effect takes place. Maybe low oxygen levels can inhibit the urge to breathe, I don't know. I was close to losing consciousness from long breath holding after hyperventilation only once. In that episode, I had strong urge to breathe which eventually disappeared and was followed by a tranquil feeling and a state of reduced consciousness with abstract thoughts. After that, there was a sense of impending fainting which I was able to recognize as the appropriate moment to get out of water, and then I left the water immediately.

ok, interesting, that your urge to breathe disappeared, because I tried holding my breath today after breathing out and it's sooo difficult to even hold your breath to the point dizziness sets in.
Wouldn't breathing into a bag be an option? You wouldn't have the urge to breathe I think, because you are breathing, only that it's no oxygen, but co2...

i saw another post about shallow water drowning (? i think it was called) where you hyperventilate then fall into water or whatever

Lots of people reported similar difficulties, so it's a very common problem. And I don't think that there is some wonderful breathing technique that would make it easy for everyone or at least for majority. My near-blackout experience appeared out of an attempt to beat my own best time of longest submerging. Bearing that urge to breathe wasn't easy at all, it was a rather unpleasant challenge that took a lot of willpower (perhaps it was more unpleasant than aspiration of water into the lungs could be).

Breathing air containing high concentrations of CO2 results in the sense of suffocation which can be considered an equivalent to the urge to breathe something specifically without excess of carbon dioxide.

Correct me if I'm wrong but this in and of itself is a non method because even if you lose consciousness your unconscious body will breath reflexively.

I could see this or something like "the pass out game" being useful when combined with another method like partial suspension where you essentially make yourself pass out into the noose. It's done by crouching down to the ground with your head down, breathing deeply for about 30 seconds, then standing up very quickly.

Update: I just tried breathing in a bag while running around to burn more oxygen and it actually worked, even to the point when my fingers started to tingle and my perception of the things around me became damped like someone put cotton around me.
At first, breathing into the bag was like you said, a little like suffocation, but after a few seconds I got used to it and it was less uncomfortable.
I used a 3 litre plastic bag (a freezer bag to be precise), wrapped it around my mouth and nose and then ran around in my flat, sometimes breathing through my nose, sometimes through my mouth, the one that was more comfortable for me at that moment. I don't recommend using a bag which volume is under 3 litres, as it's probably going to be too less space and you are going to breathe against the bag itself the whole time. And I wouldn't describe it as a life changing experience, but would take it in consideration as a coping mechanism maybe or an opportunity to escape reality for some time.
