Ok I've read through the vast majority of this thread and I just want to confirm, is possible or not to use a regular nitrogen regulator, the one with the round gauges, not the clickstyle litres per minute one. I don't think it's going to be possible for me to get a litres per minute regulator where I live and I can't just order online since the fittings are different by region/country. I want to combine exit bag with another method so precise flow doesn't matter to me too much. I just need to get some continuous flow going. Thanks for any advice!
Yes I've looked at online welding stores in my country. But they do not sell nitrogen regulators which measure litres per minute. The clickstyle regulators advocated here are for medical use, not welding.Have you looked for nearby welding stores? I'd be surprised if there is a country that doesn't have welding stores. I also didn't think to look there for the longest time, but when I did I found one a few towns over that sells almost every regulator imaginable; it was like finding the holy grail.
Have you sent any emails? I'm sure at least one of those stores will be able to source you a proper regulator with the right fitting. They might even have products that aren't mentioned on their website (if they have partners for example)Yes I've looked at online welding stores in my country.

No I haven't but it's worth a try.Have you sent any emails? I'm sure at least one of those stores will be able to source you a proper regulator with the right fitting. They might even have products that aren't mentioned on their website (if they have partners for example)
Wish I could help with your original question though.
1. Best to be in a reclined position with less chance of displacing the bag.I have a couple of questions:
1) How important is it to stay in a upright position, and why?
2) i have a regulator that says max 180 bar pressure. Is it dangerous to use 200 bar gas tank?
Is a higher flow rate necessary and would it cause unconsciousness faster?If you choose to use a higher flow rate than suggested, just make sure that you have sufficient gas. Best, G
@Greenberg if a higher flow rate is used will unconsciousness occur faster or does it not matter?If you choose to use a higher flow rate than suggested, just make sure that you have sufficient gas. Best, G
1. In the "Peacefull pill handbook" Hypoxia/exit bag section it says: "Do NOT lie down":1. Best to be in a reclined position with less chance of displacing the bag.
2. For safety reasons, I would not suggest using a 200 bar pressurized tank. However, 180 bar is equivalent to 2610 psi and 200 bar is almost 3000 psi. I doubt your supplier will fill the tank to the tank's maximum pressure. I would advise that you check with your supplier.
Of course it matters. It's almost impossible to crunch out all air from a bag. As more flow, as quicker the remaining O2 will be removed out of the bag. Unconsciousness depends on the level of O2 and so is directly connected to the flow rate. Also the positive pressure, which stands against new O2 from the neck, depends on flow rate.Is a higher flow rate necessary and would it cause unconsciousness faster?
if a higher flow rate is used will unconsciousness occur faster or does it not matter?
@FromGermany I don't see any videos or video links.Click on the triple-bar-menu-symbol at the video thumbnail. The videos in the playlist are shown there.
@Mors did you ever test your nitrogen set up?Theoretically yes, if the oxygen concentration is below 8% or so.
I believe that it will be low enough if the exit bag method is done correctly and it should certainly be be low enough if using a SCBA mask with demand valve for unconsciousness to occur very rapidly before hypoxic symptoms become noticeable or distressing.
I plan to test my SCBA mask/demand valve this weekend. I am very interested in determining what symptoms I experience, if any, and how long it takes for me to start becoming unconscious.
It's about this post.@FromGermany I don't see any videos or video links.
You should use Nitrogen 2.8 minimum. This has still 99 % purity. Regardless, which puritiy you have, 20 L/Minute should be the minimum flow.Thanks!
But I've read some resources and PPH but still not sure about my setup (because of not pure nitrogen, and my bad English probably)
Maybe somebody can give any advice? I'll be very thankful.
If my nitrogen is 97% pure (and I don't exclude the worst case in 95%) do I need to adjust the flow rate or bottom bag tightness to non-standard? Now the tightness is such that it leaves small marks on the neck, and the flow rate is 15 liters per minute.
@FromGermany not convulsions, but involuntary movement of the body arms moving ect .. it's just the brain shutting down.Exactly, and as I have pointed out, 15L/m is not optimal. It's the minimum only.
And there has to be gas for 60 minutes.
Very thick oven gloves, so that it's hard to rip off the bag or helmet when one loses consciousness. Many movements are directed towards the head. Most people have convulsions with Nitrogen as the study of RAF Institute of Aviation Medicine has proven.
The complete set must hold for 10 minutes, because then the death of the brainstem is imminent, and there is no way back to consciousness. Heart and lungs need more time to give up, perhaps 20 more minutes.
Even it all these things can happen quicker, one has to calculate, there is always an exception to the rule.
If one will be rescued within the first 10 minutes or something bad happens to the bag/helmet within the 10 minutes, then there is a very bad brain damage without any chance of recovery.
So higher flow rate than 15 L/min, enough gas for 60 minutes, oven gloves, sitting upper body taped in an armchair and some other things one has to think about.
@FromGermany you make it sound as if absolutely everyone has convulsions. They don't. Even the pig being euthanized with nitrogen didn't have convulsions.Scientists and professional gas suppliers, who are working for hundred years or longer in the gas industry, must be idiots when they claim, this are convulsions, because exit guides know it better.
This back and forth with that Exit guides narratives will lead to nothing. I will only say, don't twist my words. It's a proven fact, that I have wrote several times on the forum, that not everybody will have consulsions, but many and that I am writing for the worst case scenario, which includes convulsions, because I have a responsibility for my writings and I will not put the health of other people in danger due to Exit narratives, hearsay, dangerous superficial knowledge, 2-fingers-stories or handpicked information.@FromGermany you make it sound as if absolutely everyone has convulsions. They don't. Even the pig being euthanized with nitrogen didn't have convulsions.
