Could someone clarify a thing for me

For the EEBD hood method you don't need the adapter thing to be able to hook the cilinder to the breathing apparatus, right?

The cilinders in my area all W 21,7

So exactly what I was afraid of, the tubing doesn't fit (it's extremely loose) without some kind of connector. I even tried to make sure and asked several times here if it'll work/what size to get for my regulator, but it doesn't fit anyway. So if anybody could help, I'd really appreciate it. Even better would be a DM with source to the exact thing I need be it different tube or way to connect it. (EU)
Thanks in advance!

Nope, from what I've seen on this thread, you don't need an adapter. You can cut the metal thing off the end of the hood hose, then attach the hose to a gas regulator, which attaches to the cylinder.

Hose clamps can be used to connect the EEBD hood to the gas flow regulator. You may not have enough hose length, then you can extend it using an additional hose, hose connector and hose clamps

You can read the manual that vizzy made

It seems some EEBD hoods can be connected to the regulator in a more elegant way, there are adapters for them, but I'm not versed in that
I have discovered the name of the quick couplers used in SCBA and some EEBD Hoods, they are called "Breathing air couplings". They are not compatible with the typical compressed air couplings and they're usually available for in 1/4", 3/8", 1/2" thread sizes.

This couplers enable the connection of EEBD hoods with such plugs directly to inert gas regulators (in EU most of them have G1/4" outlets).​
Here's an example of how to use the adapter:
Here's my Rescue Hood setup:

- 9 Litre nitrogen cylinder(200 bar)
( BS341 no. 3, 5/8" BSP(British standard) outlet )

- Argon regulator with flow meter. (BSP/British standards - G 5/8" BSP inlet (to cylinder). G 3/8" BSP outlet (to coupling)
(~12.5lpm argon =15lpm nitrogen; will probably use 15lpm argon, = ~ 18lpm nitrogen).

- Rescue hood with 1 metre hose (CEN-type hose plug, compatible with CEJN 340 series and rectus 95 ks series couplings /couplers).

-Rectus 95ks female 3/8" BSP (British standard) coupling /coupler

- Adjustable wrench

You just need a thing called a hose clamp, and a screwdriver. You'll get them in hardware stores or online.

Download
Just tighten it around the tube where it's attached to the regulator. Use a screwdriver.

Or get a hose clamp that you can tighten with your hands, that look like this(called butterfly hose clamps):

I haven't seen hose clamps that small in diameter. As I understood the inner diameter of her tube is 6 millimeters, and this hose sits loosely, that is, it is necessary that the hose clamp shrinks to a diameter that is less than 6 millimeters (probably not 6 millimeters, you have to look at the outside diameter). I'm not sure they exist

No problem. Most people would never have a need for hose clamps, or come across them, so it's normal not to be aware of them.

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.

As I understood the inner diameter of her tube is 6 millimeters, and this hose sits loosely, that is, it is necessary that the hose clamp shrinks to a diameter that is less than 6 millimeters (probably not 6 millimeters, you have to look at the outside diameter).

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 think you the ones which are to be tightened with a screwdriver. Small ones exist, you just have to look around a bit, I have the same problem and just ordered some small ones a few days ago.

I also think glue would be a bad idea.

Anyone has an idea as to what an optimal bag size is? I have ordered different sizes of oven bags (43cm x 55cm and 55cm x 60cm). The PPeh recommends a size of 35cm x 50 cm. Which size should I choose? I have quite long hair so I need some space for my hair bun. But I am not sure if the CO2 is purged as fast from a larger bag as it would be from a smaller one.

The next thing I was wondering about was the tube. @GasMonkey and others suggested simple oxygen tubing, I have ordered that and some 6mm PVC tubing which also was recommended. The diameter of the oxygen hose is quite small, would it be sufficient for a flow rate of 15l or 20l per minute? I will do some test when my stuff arrives, I was just wondering if anyone has any experiences. I am not sure about the lpm, PPeH suggest 15, but I am not fully convinced if it is sufficient, @FromGermany raised some doubt. I think I might go with 20lpm just to be save.

I came across a post before from @GasMonkey, where he linked exit bag instructions. Think it's from 2015 PPeH. Measurements put forward seem to be different to current PPeH advice. I guess go with whatever size works best for your head size.
Copy of his post is below.

Screenshot 20231226 135029

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 am not sure about the lpm, PPeH suggest 15, but I am not fully convinced if it is sufficient, @FromGermany raised some doubt. I think I might go with 20lpm just to be save.
Probably go with 20lpm or higher if you have plenty of inert gas.

Thanks, guess I will have to do some tests then with my small test cylinder.
Probably go with 20lpm or higher if you have plenty of inert gas.
So you also think that a flow rate above 15lpm is better? I could even do 25lpm, with my 1000l I'd have gas for 40 minutes which should be sufficient (considering the Dignitas case where masks were used). Well I guess there is no other way to find out than to try.

Yeah, I looked up some old posts from that @FromGermany poster you mentioned, they seemed to advise 20LPM+.
Others, like @Vizzy in this thread said maybe use 25 LPM for a hood, but that 15 lpm was probably ok for the exit bag.

Another poster did a blackout test with an exit bag and 20lpm:
So I've attempted the blackout test.

  • 2.8 Nitrogen
  • Bag Diameter. 60 x 40 cm / 20 liters / 45 micron
  • 3mm elastic cord
Inflation takes some time, if you feel the gas flow tingling your ears you need to tighten the bag more on your
forehead. Bag inflated like in ppeh pictures, however you need to keep the constant flow running.
If you turn the gas flow down gas will deplete very fast from the bag.
The bag was done the same as the doing it with chi video.
I did not hyperventilate.

This shit was wild, pulled the bag down, took a few breaths. Pulse oxymeter started pinging like crazy.
After that i just remember wild noises, hard to describe but a bit like experimental electronic music.
I think i only regained consciousness because I headbutted the cabinet in front of me.
Cylinder knocked over, pulse oxymeter lying on the floor, head bloody.

I have no recollection how long it took.


So you also think that a flow rate above 15lpm is better? I could even do 25lpm, with my 1000l I'd have gas for 40 minutes which should be sufficient .
If you've got enough gas, you might as well go with 25lpm.

Yeah, exactly. I know that he had a major spat with @Greenberg and that he was banned (not entirely sure why, but it seems like he was to critical), but I read a lot of his posts (in other threads too) and his reasoning seemed valid - for instance I too think that the simple scuba setup by @befree and Scrooge is crazy (although one guy successfully ctb'd). Concerning the lpm, he even quoted a study by Ogden where it is supposedly established that one should use a higher flowrate. I'll see if I can find it again.

A blackout test with an exit bag is totally crazy tough.

Yeah, in the thread I was looking at, @FromGermany and @Greenberg seemed to be constantly arguing. Before, when looking back over the previous few pages on this thread, @Greenberg was mentioned a few times, so maybe people sided with his views more. I honestly don't know.

Why do you say that the simple SCUBA setup by @befree is crazy?

Yea, I presume the blackout test with the exit bag is done with the tube not taped to the inside of the exit bag, and just left loose. There's always the chance it could stay inside the bag when the body falls though. Blackout tests should only really be done with SCBA/SCUBA gear.

Study of Hamilton WK, Eastwood DW, "To completely replace expired air, and thus insure the highest possible concentration of helium, the flow rate of added gas (helium), has been determined to be a volume of at least two and one half times the subject's minute volume. This would be true with either the bag and mask as used by Dignitas, or with the use of a large hood."

This also applies to Nitrogen.
10 Liters x 2.5 = 25 Liters / Minute

Derek Humphry, Final Exit 2020, "For the nitrogen method set the nitrogen regulator outlet gauge at 20 liters per minute (LPM)."

Also, only a 2 stage regulator will ensure a stable flow for the tank. An ordinary 1 stage premium regulator with a flowmeter will also do the job as long as there is at least a 10 Liter Nitrogen bottle (10 x 200 = 2.000 Liter) and a purity of at least 2.8 of the gas.

I found @FromGermany's quote in another thread. He got the authors of the study in his first quote wrong, it actually comes from this paper. The german wikipedia says this about minute ventilation: "An adult human takes about 12 to 15 times per minute. He inhales a tidal volume of 500 to 700 ml per breath. This means that his minute respiratory volume is on average eight liters (13 × 600 ml = 7800 ml) per minute."
So even if we go with 8, which is lower than @FromGermany's number, one possibly should at least choose 20lpm (8 x 2.5).

I don't agree that you need a 10l cylinder though. 5l should be sufficient, even in the worst case - the one from the Dignitas study where it took one person 40 minutes to ctb. And like it was said multiple times, this was the case because they used face masks that weren't tight. I think here he is just overly cautious.

Why do you say that the simple SCUBA setup by @befree is crazy?

In the case of the cheaper version one has to use a mask where nasal breathing is not possible, because the nose is obstructed. I must admit, I have no idea how unconscious breathing works, but the nose should be free I guess? Also there is the issue of the mouth piece: Scrooge recommended to remove it, @befree to keep it in. I'm not sure how high the breathing resistance is with these kind of masks. What happens if one is unconscious and breathing through the mouthpiece gets tougher because one does not have it in the mouth?

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?

Do I have to buy a reducer that is designed for a different gas? Because the argon reducer, for example, has measurements of liters/minutes

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):
This is my regulator. Thank you!

There is both CO2 and argon units, the argon is on the side.

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.

Yes you should be able to use it.

For the LPM flow it just makes a small difference.

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

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...

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:
287MA 15L2 0

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.

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).
