Method Exit bag and inert gas megathread

[Justnotme]

If you can't get a nitrogen regulator/reducer with LPM on it, then the Argon one with LPM flowmeter is fine to use, I've seen other posters on previous pages use it. There's a slight difference in between nitrogen and argon, but from what I saw on this thread, setting it to 15lpm on the argon flowmeter gives just under 20lpm of nitrogen. So it's fine to buy the argon reducer/regulator, and set it to 15lpm.

Here's previous posts from @DyingToDie123, who used a regulator that measured both argon and carbon dioxide(CO2):

Thank you for answering me!

 

[Tears in Rain]

Thank you for answering me!

No problem, I found a couple of other previous posts that mention using an argon regulator with Nitrogen:

Correct but its not a huge difference. Argon is a heavier gas anyways so 15LPM on an argon-calibrated regulator is closer to ~20LPM for nitrogen

Okay great thank you so much for your help, I was also thinking of using this regulator but I think it's an argon regulator with carbon dioxide. It can connect to a nitrogen tank so I'm wondering if I could use it and replace of a nitrogen flow meter and regulator.

Amazon product ASIN B01I67VKFW

Yes you should be able to use it.

For the LPM flow it just makes a small difference.

 

[Intoxicated]

Guys, please tell me what should I do if in my country the nitrogen reducer does not have a rotameter where liters/minutes should be indicated?

How about trying to find other regulator, like А-30-КР1-М?

 

[Justnotme]

How about trying to find other regulator, like А-30-КР1-М?

Are we from the same country? I just don't know very well yet which regulator are supplied to different countries.

Anyway, thanks for the tip... For some reason, I didn't notice this regulator. I do not know why

I'm telling you, my brain is already not functioning well. Stress, eternal stress, pills have already eaten half of my brain

Thanks again

My experience was that I soon began to feel tingling in my hands, as if they were falling asleep. A short moment later I began to get dizzy, and my vision went grey around the edges. Each of the three times I have attempted this method, that's as far as I got before I flinched and removed the bag.

I did not experience any pain whatsoever, and no real discomfort aside from the mild tingling in my hands.

I do not believe I have suffered any ill effects from three aborted attempts. I had a bit of a cough for a couple days after my third attempt, but I can't say for sure whether that was attributable to the N2. It concerns me only in that this method demands that you be able to breathe freely in order for it to be effective, and I don't want to have ruined my chances to use it later, when I have summoned my courage.

My greatest difficulty is that I have been very stressed during my attempts, and could not keep my breathing steady and deep. This undoubtedly lengthened the amount of time it should have taken for me to black out.

In the stress of the situation, I experienced time dilation —in other words, I can't tell you how long it took for me to feel dizzy; it might have been five seconds, it might have been a minute and a half. It wasn't very long —but it was long enough for me to flinch.

From my experience, this is as painless, comfortable, and potentially peaceful a way to ctb as it is rumored to be. The only drawbacks that I can see are that it requires a lot of equipment —cylinder, regulator, hose, bag— and that there is a surprising amount of time for your survival instinct to kick in, or for second thoughts.

As I wrote at the beginning, I hope other forum members can fill in some of the blanks I have left —specifically, I have seen a lot of questions about tank sizes outside the US that I cannot answer.

I don't wish anyone good luck at catching the bus. I wish we could all find our way to a joyous and satisfying life that would make death an unfortunate reality rather than a longed-for relief. But all of us here know that the Fates aren't always that kind, and so I wish you all the most peaceful relief from your pain that you can find, and if that peace is brought by Death, I hope Death comes gently.

Hello, I am a new member so apologies if my questions are dumb:
one thing I can't understand is how to fit a regulator to the specific cylinder + which "hose" should be connected to the cylinder and go into the bag?
If it is an oxygen tube you're talking about (oxygen tube=hose?) than it is hard to find an oxygen tube that delivers 15Lpm... I only found ones that deliver up to 10.
Plus if I do find one oxygen tube, then how is the oxygen tube connected to the cylinder???
I've read about using a hose clamp, but I am not sure about how to connect a hose clamp to an oxygen tube???
Can anyone please explain this part? I will be very grateful... that is what I'm mostly have trouble with comprehending.
In the Max Dog brewery video it looked easy to connect the plastic tube to the regulator but they are no longer active from what I'm seeing...

Hi, your questions aren't dumb.
If you're going with the exit bag, regulator and cylinder, then you first connect the gas regulator to the cylinder (you just screw on the nut). Then you attach one end of the oxygen tube to the regulator (they usually come with a thing called a barb, to attach a tube to). Then you tape the other end of the tube to the inside of the exit bag.

You'll need a regulator that has readings of litres per minute (LPM). It's usually a regulator with a flowmeter that has LPM.


But some people were able to get regulators called nitrogen click-style regulators, where you twist a knob at the end to adjust the LPM:


You just adjust a nut on the regulator to connect it to a cylinder. Here's how your setup will go together:

After attaching the regulator to the cylinder, you put the end of the oxygen tubing through the hose clamp, and then attach the tubing to the regulator. Then slide up the hose clamp to where the tube is on the regulator barb. Then tighten the clamp with a screwdriver.
Here's a photo of oxygen tubing connected to a regulator (but not yet connected to the exit bag):



You'll need small mini hose clamps. See post below and posts on previous page for info about small hose clamps:.

Use two clamps at the connection, if two will fit; If only one fits then that's fine.
And you'll need to get small hose clamps, sometimes called mini hose clamps. Your tubing is only 6mm, so you'll need either 6mm or 8mm hose clamps. Buy a couple of each size, and see what fits best. You can also buy a set of hose clamps, that come in a few different sizes.

Just make sure the tube is tight on the regulator.


Good spot, I hadn't thought of that. But on looking it up, you can get hose clamps, sometimes called mini hose clamps, as small as 6mm. Given that the external diameter of a 6mm tube could be 8-9 mm, a clamp of maybe 8mm diameter might be ok. @FailerQt. should try the different size clamps to see what fits best.

I don't know anything about the oxygen tubing LPM, maybe PM posters from previous pages who are using tubing and the Exit bag.

Once you have the setup:


In a previous post I posted, @GasMonkey linked pdfs and videos on making an exit bag. Some people buy turkey bags or oven bags. I'll repeat his post below:

Read the inert gas chapter on the PPeH and PPH Essentials.
There is a PDF with instructions to craft an ExitBag. There is also a couple of videos: Doing it with Chi and Doing it with Betty.

I'm going to leave home with a helium balloon tank. According to the seller, the content is 99% helium and not 80% helium and 20% air. I'm going to check the gas purity of the content with a meter. If the content is not suitable for this purpose, then argon

You are right to test the helium purity.

You may already know this, but you cannot attach a gas regulator to those helium balloon cannisters, and there doesn't seem to be an adaptor that goes between a regulator and a cylinder like that. There was another thread a couple of weeks back where the person was doing this method with a helium tank without a regulator, and several people urged them to use a regulator, as you can control the gas flow.
Is your helium tank connection the same as that posters?

However, if you have no other option but to use helium balloon cylinders, maybe you should at least use 2 of those cylinders hooked up to a t-joint, as some people advised on that thread I mentioned. At least then you will have more gas

I came across a piece where two elderly women allowed their ctb to be observed by a person for research purposes. Both were using the helium cannister exit bag method, but one used one helium cannister, while the other used two connected to one tube using a t-joint(or y-shaped barb joiner). I suggest you do the latter if you are unable to get a cylinder that takes a regulator.

Y-shaped and T-shaped 3-way joiners

I'll attach the piece below if you want to download it, it shows how the two women accepted their death(but be warned, it contains graphic images of the deceased women at their passing).

I found the same article and was wondering about the following passage: "While there was no evidence that the decedents experienced any pain, it was disturbing to witness preterminal gasping in both cases. In adults, gasping is witnessed in 30% to 40% of cardiac arrests" (p. 160).

I don't quite know what to make of this passage. Was the researcher simply disturbed by the sight of this or is this gasping a sign of something else, like pain? Are they having a cardiac arrest?

The researcher was simply disturbed. The person looks like they are on their way out, then all of a sudden the body seems to be gasping for air. I'm sure it's strange to watch, especially if you haven't seen it before.
From looking it up, gasping like that is not a sign of pain:

'In various animal species, gasps only occur with deep hypoxaemia when the partial pressure of oxygen drops to below 5 to 15 mmHg. Gasping indicates approaching death. Scientifically, everything suggests that gasping patients do not feel pain or respiratory discomfort since clinically there is no objective evidence of residual' consciousness'.

I don't get this perfect seal thing w7th an exit bag ... I thought it has to have some whole so the co2 can leave... When using nitrogen the gas flow will lead to co2 (which is heavier) to be able to leave through the whole

If a small hose is connected to the bag... Shouldnt the co2 be pushed out there? I dont get how it leaves if its snug fit but i havr no experience with the flow rate...


Another question.... If i sit on a chair under a big sack (enclosed) ... And the Sack is full and gas still flowing... Shouldn't i die? Even if the co2 would rise in there i guess it would take too long to breath that co2 (should be at the bottom) and you should be unconscious anyway? The co2 ist only bad because you get the feeling to suffocate and that will endanger the attempt...
Does someone have experience with these eebd hood from drager?

I don't really understand how this all works despite reading for EEBD hood.

First, I need to find a place that sells a Drager hood.

Then I need a ACU-200 Regulator. The only one I found is argon/co2. Will that be a problem?

Then I need two couplers: CEJN, 1/4NPT, Series 344, and a male-male CGA-032 to 1/4".

The regulator connects directly to the nitrogen tank? Then one of those couplers connects to the regulator, and another to the mask hose? Then you connect the coupler coming out of the regulator to the one at the end of the mask hose?

Am I even in the right ballpark? I've never worked with any of this stuff.

What the heck are these connections? If i have a nitrogen cylinder with g1/4 outlet.... What would i need if I want to connect it to the dräger masks? Are they all the same for ctb? I found the panorama mask but without filter.... What is this filter? Is it required? Why is this so complicated. :(

 

[Intoxicated]

Another question.... If i sit on a chair under a big sack (enclosed) ... And the Sack is full and gas still flowing...

I don't understand the idea. If gas flow is present, then the exit bag has to be open or semi-open. If there is no gas flow, then the exit bag has to be completely sealed.

Even if the co2 would rise in there i guess it would take too long to breath that co2 (should be at the bottom) and you should be unconscious anyway? The co2 ist only bad because you get the feeling to suffocate and that will endanger the attempt...

I haven't seen any evidences that people who passed out from hypoxemia can wake up due to accumulated carbon dioxide, except maybe when fainting is caused by a synergetic effect of hypocapnia (induced by hyperventilation) and hypoxemia (induced by low O2 in the lungs), so a sealed exit bag of a sufficiently large size should be a viable option.

Thanks for the quick reply... I am just thinking about alternatives to the small exit bag because i am afraid that the co2 won't displace...
Just so desperate... It has to work...

And i thought with a big bag there's more room... I stick the hose to the inside of a bag, prefill it and hold it... Gasflow still on and than pull it over me... It will still be open at the bpttom of the chair...know that i rethink about it...
If i can get a bag where i can fit in, it would even be sufficient to just fill it completely... I just realized i won't be able to close it once inside... I want a sarco :(

 

[Intoxicated]

Thanks for the quick reply... I am just thinking about alternatives to the small exit bag because i am afraid that the co2 won't displace...

I think, the effect of CO2 is commonly overrated. I didn't notice any symptoms of hypercapnia within a minute at all even with a small bag. One minute should be sufficient for losing consciousness, so what's the point to care about CO2 then? The main reason of using a large bag is prevention of getting a high concentration of O2 in it after some amount of air enters the bag from the ambient atmosphere and from the lungs. Bigger space for CO2 is just a small bonus that doesn't play a big role. Besides, if you want to defer hypercapnia effects even more, you can just hyperventilate before putting the bag over the head, so you'll have 2+ minutes with nearly zero urge to breathe with fresh air.

I stick the hose to the inside of a bag, prefill it and hold it... Gasflow still on and than pull it over me... It will still be open at the bpttom of the chair...

You should consider holding breath during the period between putting the bag over the head and sealing it completely, otherwise you can pass out before sealing is done. One minute should be more than enough for sealing the bag. Hyperventilation can help at long breath-holding.

Hey people
I want to know the how many litres we require to kms and also I'm a student and i live with my friends so i need to sneak the container and hide it, so i think it would be better if the container is small, is that even possible? Also I'm from India. Anyone here from india?

 

[Tears in Rain]

IfIf a small hose is connected to the bag... Shouldnt the co2 be pushed out there? I dont get how it leaves if its snug fit but i havr no experience with the flow rate...

The bag will be filled with nitrogen/argon/helium before you pull it down over your head. When you pull it down, you will start to exhale CO2. The heavier CO2 will be purged down to the bottom of the bag by the lighter nitrogen, and out the small gap in the bottom(there'll be a tube going into the bag). You will be unconscious in 30-60 seconds. Any CO2 that hasn't been purged out the bottom won't be enough to cause hypercapnia (excessive CO2 in the lungs). You will be inhaling the inert gas.

Another question.... If i sit on a chair under a big sack (enclosed) ... And the Sack is full and gas still flowing... Shouldn't i die? Even if the co2 would rise in there i guess it would take too long to breath that co2 (should be at the bottom) and you should be unconscious anyway? The co2 ist only bad because you get the feeling to suffocate and that will endanger the attempt...

I don't get why you would use a big sack instead of a smaller bag. The smaller the enclosed area, the easier it is to fill with the inert gas.

Does someone have experience with these eebd hood from drager?

From what I saw going back over the thread, people used to recommend the Draeger EEBD hood, but then some people said there was no exhalation valve on the Draeger hood they got. I'm not sure what type of Draeger hood it was, have a look over the older posts.

What the heck are these connections? If i have a nitrogen cylinder with g1/4 outlet.... What would i need if I want to connect it to the dräger masks? Are they all the same for ctb? I found the panorama mask but without filter.... What is this filter? Is it required? Why is this so complicated. :(

If you go for the EEBD hood, just get one without an air cylinder attached, which they are sometimes sold with. (Some people here before have gotten them fairly cheap on Chinese shopping sites, one beginning with A in particular). Then all you need to do is cut the metal connection off the end of the EEBD hood hose, slot it through one or two hose clamps, then attach it to a gas regulator flowmeter, that has litre per minute readings. That regulator will be attached to the cylinder.
(Like I said in a post above, some people have used exit bags connected directly to helium balloon cannisters, without a gas regulator, but it's advised to use a regulator to control the gas flow).

The connections you linked above are not needed. When I went back over the thread, I saw that one poster, @GasMonkey, found a way of connecting two brands of EEBD hood(one a Draeger hood, one a Scott ELSA hood) directly to a gas regulator without the need to cut off the metal connection at the end of the hood hose. He found a connector, called a coupler, that those two types of hood hoses could be directly plugged into, and then the coupler can be screwed onto the regulator. So it avoided the need for any cutting of the hose.

The hood hose, with the end connector cut off, and connected to a gas regulator with hose clamps looks like this:


Whereas a hood(certain Draeger or Scott hoods only) connected to the regulator with a coupler looks like this(no hose clamps needed):


Like I said, it seemed that the coupler connections you mentioned only worked for certain hoods. As well as that they were expensive, and seemed difficult enough to source.
From my point of view there's no need to go buying those couplers. Just cut the end connector off the hood hose, and connect it directly to the regulator with hose clamps. It's cheaper, and less hassle.

THANK YOU very very much @Tears in Rain for this information, it is very helpful. I am slightly technophobic so stressed about the installment . I have another question if that's okay: in Israel they don't measure tanks by cu ft, (from my understanding, the cylinder needs to be 40 cu ft to make sure), but, by liters. In google they say 40 cubic feet = 1132 liters or something, but in Israel the cylinder comes 40-50 liters.... does that even make sense?
In terms of the gas purity, there is up to 99.99999 purity which I think is okay, but I'm confused about the measurements ...

also, does anyone have a good cover story? I told that my family is opening a beer brewery and put me in charge on contacting suppliers... but I'm worried they will ask more questions....

It's recommended you get at least a 5 litre cylinder, which are usually sold at 200 bar for nitrogen, which gives roughly 1000 litres of compressed gas. If you're in a region that advertises them in cubic feet, get a 40cu/ft one.(gives roughly 1100 litres of nitrogen).

Thanks for the reply... I checked the old posts but its so much.... Scba positive pressure, scuba negative, which is not good..eebd mask even more complicsted and the eebd hood... Looks like an expensive professional exit bag.... My issue, i cant find the hoods with an already attached hose in my area...and also without the o2 cylinders... And then its too pricey for the benefit it gives... Which currently i can think of is no exit bag preparation and exhalation through valve bit even that seems to be not reliant...

Eebd mask
And these couplers seem to be required for the other eebd mask like drager, they have no hose outlet...the connection is called rd40 and seems to be for filters (font know what kind and if necessary if used off label) ... But from there... I dont understand how to connect this to the hose of the cylinder... As you said difficult to source..
And as you said there seemed to be differences regarding the types and exhalation capacity... I guess exit bag will be safer without references in my country... Would love to have a system already working for my country...


The regulator i want to buy is only in bar and has no hose attached... Just theinfo 6,3mmx6mm... Have to get a hose for that...

So there's a seller with 6l cylinder for 700 rupees (which is less that 1 dollar) will that be enough? The other sellers are only selling 7 cubic meter and i think it's very huge

No problem.

I just posted about that above, before I saw your response. 40-50 litres is a lot, that's gonna be a big, heavy cylinder. Get a 5 or preferably a 10 litre. But obviously a 40-50 litre is fine if you can't get smaller and can transport it ok.

It can be confusing alright. They advertise the cylinders as litres in water volume in some countries, e.g. 5 litre, 10litre, 40 litre etc. To get the rough amount of compressed gas in litres, you multiply the water volume by the bar pressure. So a 5 litre cylinder at 200 bar pressure gives roughly 1000 litres of compressed gas. Confusing, I know!

That purity is fine. If you wanna be sure, you can test the purity yourself using an oxygen detector(but most people probably don't bother testing) Here's what @GasMonkey used:


They probably won't ask questions. Just say you or your partner are using nitrogen to make home brewed beer, if they do. Or for your uncle/brother/ father who's a welder.

plus will the oxygen tube fit the regulator for certain? how do I know where to fit it into inside the regulator?

The tubing goes on the outside of the regulator connection, on a thing called a hose barb that usually comes with the regulator. Here's a photo of @FailerQt.'s tube on the regulator hose barb, from the previous page on this thread.

You just need to get small mini hose clamps to secure the tubing (see their posts on the previous page).
Hose clamp:


I just noticed today that the PPH recommends using tubing with soft connectors at each end, because it makes a thicker connection for any hose clamp used:

It's recommended you get at least a 5 litre cylinder, which are usually sold at 200 bar for nitrogen, which gives roughly 1000 litres of compressed gas. If you're in a region that advertises them in cubic feet, get a 40cu/ft one.(gives roughly 1100 litres of nitrogen).

These are the details

My issue, i cant find the hoods with an already attached hose in my area...and also without the o2 cylinders... And then its too pricey for the benefit it gives... Which currently i can think of is no exit bag preparation and exhalation through valve bit even that seems to be not reliant...

You can get relatively expensive hoods, with only the hose attached, on a certain U.S. auction/ bidding website. But some posters here have bought them far cheaper on Chinese shopping sites ( like I said previously, one beginning with A seemed popular). And the Chinese ones come with an exhalation valve.

Eebd hood source for nitrogen gas method (Inert gas method)

Guys anyone looking for a eebd hood to buy for their nitrogen gas method (inert gas method), let me know I can help you to buy it for cheap as it is expensive to buy and many sellers won’t sell to the individuals buyers It doesn’t matter anywhere in the world and if you need only one piece, my...

The regulator i want to buy is only in bar and has no hose attached... Just theinfo 6,3mmx6mm... Have to get a hose for that...

You need to get a regulator with a flowmeter, the flow meter will have litres per minute readings on it. ( Or look for a click-style nitrogen regulator).
You don't need to get a regulator with a hose; either get the EEBD hood with the hose already attached, or if you go with the exit bag, use oxygen tubing.

So there's a seller with 6l cylinder for 700 rupees (which is less that 1 dollar) will that be enough? The other sellers are only selling 7 cubic meter and i think it's very huge.

I can't tell how many litres of compressed gas it has without knowing what bar pressure the cylinder is. (You multiply the cylinder water volume by the bar to get the rough compressed gas amount).
Less than 1 dollar? That seems very cheap for nitrogen.

Yes less than a dollar that's why I'm worried and to that he didn't mention bar pressure
I attached a picture of details hope it helps to figure

Sorry, but without the bar pressure, I can't work it out. I thought first, given that it's so cheap, that they may be selling a cylinder without the gas in it, as some sellers do(leaving the buyer to refill it themselves). But they are advertising the purity, so there must be gas in it.
I can't help you with that one. Try and find one that advertises both the litres and bar, then multiply to get the total litres of compressed gas. Aim for at least 1000 litres of compressed gas.

Ill go with the exit bag... As the hose attachment states 6mm diameter i am not sure.. Should i buy a hose with an inner diameter of 6mm or can it be 4mm? https://amzn.eu/d/2YFk5UZ do you think this could work or do you have a link?

I googled the oxygen tubing but i find no info on the diameter (found some for nose with way too little diameter though... and they seem to have something attached to them... That i can just cut off i guess? Its difficult to source stuff if communication is between two different languages...

 

[Tears in Rain]

From what others have said here, I think the standard oxygen tubing inner diameter is usually 6mm inner diameter. That will fit on fine to a regulator hose barb.


Then just use mini hose clamps to fasten it. Can you not get oxygen tube like that mentioned in the PPH?:


Look at @FailerQt. posts on the previous page about oxygen tubing. They are using an exit bag also.
