shallow water blackout questions

[Widdershins]

Hi, I had some questions about the shallow water blackout method.

How long do I have to hyperventilate for? I have done up to 20 minutes and managed to hold my breath for up to 2 minutes and have only experienced light headedness.

I have had more success with putting my head between my knees then standing up quickly and then blowing on my thumb. I have gotten really dizzy, I think if I increased the time I would pass out. My second question is if anyone has had good results from this way of passing out for the water method. I tried looking this up on the forums and the first result I got was that it could cause brain damage. :P Is that why the other method of passing out seems to be preferred?

I am new here, so please excuse me if I missed the answers to these questions somewhere else on these forums. Thank you for your time answering.

How long do I have to hyperventilate for?

I wouldn't do it for longer than 2 minutes.

I have done up to 20 minutes and managed to hold my breath for up to 2 minutes and have only experienced light headedness.

What happened after lightheadedness?

I think, that doesn't make sense to do, because such a blackout would be just temporary, while you need a persistent knock-down effect which is achieved with lowering the amount of oxygen in the blood.

Hi Intoxicated,
The lightheadedness passes and sometime after that I can't hold my breath anymore so I breathe.

Was that lightheadedness induced by hyperventilation or long breath-holding?

I was close to SWB before, I went through the following stages:

1. hyperventilating until tingling in fingers was felt,
2. submerging,
3. no urge to breathe,
4. moderate urge to breathe (it was bearable and possible to overcome),
5. urge to breathe was abolished,
6. lightheadedness,
7. sense of impending fainting,
8. getting out of water and starting to breathe,
9. sense of weakness and strong sense of heaviness in the head,
10. perceptions went back to normal.

If you're hyperventilating for more than 5 minutes and still aren't seeing results, this method might just be impossible for you.

I spent about a week researching this method in detail and tried it countless times but it wouldn't work no matter what.

As for the second method of kneeling and standing up, even if it works you might just end up splitting your head open, so on the whole it's just not a great method.

I think, I never hyperventilated for 5 minutes or more. This is just too much time, I'd get headache if I were doing it for so long. It seems, multiple cycles of hyperventilation and breath-holding have a cumulative effect, so a big number of attempts done in a row can work.

It was induced by hyperventilation.
I'll try out what you said of multiple cycles of each, thank you.

 

[Widdershins]

I tried multiple cycles of hyperventilation followed by breath holding. For the first couple rounds it resulted in increased dizziness, but after continuing some more that didn't happen anymore. :(

Why not use gas asphyxiation instead of hyperventilation with air? It should be way more easy than the plain SWB method, since it causes almost guaranteed fainting in less than a minute if you follow a simple procedure.

Hey guys, I have a question about a CTB method that I hope someone could answer. I can get my hands on diflouroethane quite easily in the form of air duster. This rapidly replaces oxygen in the blood and causes unconsciousness. So the plan is as follows: book a hotel room with a tub. Fill the...

Thanks, I'll look into it.

Hey dear, i was considering swb for ctb. What are your thoughts on it so far? I just joined today

To be honest, I gave up on it because I wasn't able to pass out via hyperventilation. Have you been able to do so?

Same shoes :(
Last night, i tried hyperventilation and i felt the light headedness but didn't pass out as yet - i have tried hyperventilation in the past but never fainted.

Initially i was thinking of using HV to faint and then, using plastic bag to ctb.

But i never fainted, that's when I kinda shortlisted SWB as i can get the privacy in the bathroom. However, i only have a bucket and no bath tub to do that.

I tried to dip my head in the water to see how it feels. I felt suffocation without HV.

In another forum post, I consulted if my idea of using bucket is good - they said that, the risk is, bucket me tip over and i might end up vegetable.

I'm kinda stuck at this point as i do not have a big water body to use this. And a bucket might not be the best option. I have a low height bucket, may be that can help - but not getting the confidence.

Fainting from hyperventilation isn't helpful anyway. SWB is passing out underwater due to a lack of oxygen in the blood. Hyperventilation is only supposed to let you be submerged for a long time without a severe urge to breathe until your blood becomes oxygen-depleted. If you faint due to hyperventilation directly, you wake up shortly after the loss of consciousness, when the cerebral blood flow becomes normal again due to accumulated CO2.

The only challenge is i am not able to find a big water body accessible. Is there a way SWB could be used with a bucket in the privacy?

 

[Intoxicated]

I know that some people really drowned in small puddles, but never heard about cases of drowning in buckets before
Well, Google suggests that buckets can also be used.

I did try this method until I was exhausted I ended up relaxing in the bathtub
Sooo this happens suddenly-
1 . Old woman hit her head against the taps and fell unconscious to the water filled bathtub and died .( No intention of ctb)

2. Happens to drivers wanting to hold their breath under water
It requires so much practice to learn to hold your breath under water.

Either become professional at holding your breath after hyperventilation ( very tough...if you succeed consider being a swimmer...time 1-10 yrs) or take meds to be unconscious then go in or .....another method.
Caution - regular practice of hyperventilation, will cause brain damage.

If you balls of steel jump in a big water body from a good height. First you will be unconscious ( due to the height) and then you will hit sea with great force( same as concrete). You dead dead
Peaceful too .
