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

The PPeH says that the bag should make a snug, but not tight fit around the neck:

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. :(

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 :(

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?

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?

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:
Screenshot 20240102 150249

Whereas a hood(certain Draeger or Scott hoods only) connected to the regulator with a coupler looks like this(no hose clamps needed):
Screenshot 20240102 150530

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.

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.
View attachment 125798

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:
View attachment 125804

You just adjust a nut on the regulator to connect it to a cylinder. Here's how your setup will go together:
View attachment 125799
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):
View attachment 125800


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


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:
View attachment 125802

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:
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....

thank you for all of the help.

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:
Screenshot 20240102 154618

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.
Screenshot 20240102 160011
You just need to get small mini hose clamps to secure the tubing (see their posts on the previous page).
Hose clamp:
Screenshot 20240102 160006

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:

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.

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.

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.

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...

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?:

Does anyone know what the purchasing laws /the availability of equipment is here in UK? I know helium is probably out of the question since all I can see are probably impure little balloon canisters online..

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 EEBD masks you talk about are presumably SCBA(self contained breathing apparatus) masks. They have a different type of regulator and hose needed.
I posted about that to another person yesterday:

У кого-нибудь есть опыт работы с этими eebd hood от drager?
Я больше не рекомендую спасательный капюшон Drager PSS. Два человека купили его и имеют проблемы с клапаном выдоха капота. Отныне используйте только капюшоны с внутренней маской, такой как китайская (используется клиентами EM, а также Vizzy и bennydiazapine) или Drager Saver CF или 3M Scott.
I recently haggled and was able to buy a new Drager Saver SF on the secondary market for about 20 euros. I had a hard time putting it on and had a hard time taking it off. It fits very snugly on my head, I wasn't expecting that. There is no connector on the end of the hose, I think only the Drager PSS hood has one. I don't have a caliper, I measured with a regular ruler and I got that the inside diameter of the hose is about 7 millimeters, it's probably 1/4 inch. I have attached a couple of pictures for those who might be interested in looking at it

Yes, some people before found them a bit tight to put on, but if it's snug when you have it on, then that's good.

Only €20 euros? You're a good haggler!😆

Oh right, I looked at that post by @ztem that you reposted. So he was advising against buying a Draeger PSS rescue hood, but said the Draeger Saver CF was ok. I got that wrong so in a post I put up earlier, I thought it was all Draeger hoods that were giving issues, but it was just one type of Draeger hood so.
I don't recommend the Drager PSS rescue hood anymore.Two people bought it and have problems with the hood's exhalation valve.From now on, only use hoods that have an internal mask like the Chinese(used by EM's customers and Vizzy and bennydiazapine) or Drager Saver CF or 3M Scott.

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.


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).

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:

Thank you again @Tears in Rain . I appreciate your help very much. I will buy the 10 liter cylinder then : ) Thank you!

Once I have all the equipment, I will see if I need further counseling and if I could get your advice then with photos of the equipment... :)
Stay safe

@Tears in Rain
Sorry, one last question ....... does anybody know what to do with the hands so that they won't rip the bag or take it off when unconscious ? Should them by tied ? how to do that?

No problem asking the questions.
If you look at the inert gas setups gallery, you'll see some people using what are called lashing straps or tie down straps:

You could strap the body, and maybe strap the arms, to a chair or whatever.
Maybe pull the bag or hood down, then put your arms under the straps.

You can tie your hands for reassurance, I would do that, although I don't know how necessary it might be.

You can use suitable straps, tightening them after you put the bag on and put your hands through the straps, you can use clamps (not sure what this thing is called in English, so I'll attach a photo), someone was going to use handcuffs, and someone thought of doing ctb in the car put their hands through the steering wheel and use a Chinese finger trap🙂
Someone, possibly vizzy, was going to use these straps
