Method Exit bag and inert gas megathread

[Sirius]

I feel like I would botch it, but I thought the cost was way more. Some maxdog regulator or something. Also, from where do you get the nitrogen tanks.

The max dog- no thought involved kit from Aussie land is like $330 and you need to get the can of nitro in your own country seperately

By all accounts it the same as helium........5 minutes or so

This will be my back up I think. But I have no place to hide a nitrogen tank. Do you have any idea how big it is?

How much does this method cost

HI Throwaway9787,

I consider it impossible to answer the question in a general way because it depends where you are living and I cannot speak for the US, India, Australia, Canada, Africa, etc but only give a rough estimation for central Europe, and even here it would depend on whether you prefer to use new material or 2nd hand material e.g. from ebay. I'd vote for new material, which makes a significant difference.

Estimation for new material in central Europe:

4.6 Helium 20 liters 200 bar - 170 Euro
pressure regulator with flow-meter - 170 Euro
zippered mattress cover - 15 Euro
tube 2 meter - 4 Euro
tape - 2 Euro
rope or belt (if you prefer) - 2 Euro


I forgot anything?

Just for the record: I've had the policia at my home on mre than one occasion because I had been a Guide. They looked under the bed, behind furniture, closets, etc. I had the nitro painted red with flowers and slapped a lamp shade on it- right by my bedside. They were so hooked into looking for helium they never saw it hiding in plain sight. I did pray to the gods of anarchy that the BS was strong with me that day
Mind you..I don't have immediate plans. This is my exit if/when my medical condition goes to sht. My Roman catholic Doc would never honor the State legalization for assistance

Hello Sirius,

What means, you "had been a Guide" ... could you concretize?

Thank you!

Sirius all I can tell you about the issue of CO2 build-up is that you're supposed to exhale as deeply and forcibly as you can to expel any remaining oxygen from your lungs before pulling the exit bag down over your head and that once the inert gas is flowing it's supposed to fill the space around your head inside the bag so that's all you're breathing and to prevent any air from entering the bag from the outside environment.

As best I recall, CO2 is a byproduct of exhalation and would accumulate inside the bag without the inert gas flowing in. Eventually enough CO2 would be present to trigger what I think is called the "hypercapnic alarm" which is that sensation of "not getting enough air" that causes people to panic. Having the inert gas flowing continuously into the exit bag is supposed to prevent this.

Thanks for that. So, as I see it, There would be little/no difference between how helium and Nitro work

If you used to work for FEN (that's Humphries' organization, right?) is there anyone you could contact to get the latest advice on the inert gas/exit bag method (assuming you keep in touch with anybody there)?

There is a difference: Helium is less narcotic (if at all any) than N2 but this is actually only relevant when diving. Helium is an inert gas while N2 is a semi-inert gas, which is actually only relevant for the material (to be) welded. Helium does replace/push out the O2 from your lungs a lot quicker than N2 does because Helium is a lot less dense than Air, and N2 is almost as dense as Air.

The "new" regime that came after my buddy, their medical director, died are not my best friends.. Kinda hung me, and him, out to dry back in the day after FEN got some media attention. My back channels tell me that Nitro is being administered and is as reliable as the helium

I will say I had a tele conversation with a still active member the other day who told me to believe nothing I read on this site-LOL Still swears by hood method

 

[Eweforia]

However I have had those tanks some time and am suspicious of slow leakage.
<snip>
Nitro canister in US $95; Make your own bag $20ish; Regulator $35

Like @Sirius , my helium tanks are seriously old and I worry that they may have leaked. That's why I'm fitting out a nitrogen tank. I couldn't find an inexpensive regulator that measured in liters/minute and had the correct barb hose fitting and standard tank fitting. Perhaps if I could do the math conversion, one of the regulators that measured in psi would work, but that is too complex for me. No one has stepped forward to offer an alternative to the $80 Hobart valve (https://www.tractorsupply.com/tsc/product/hobart-flow-gauge-mig-regulator) and I couldn't find it on Amazon so it may be difficult to find elsewhere online. My local Airgas outlet sells a 20 lb N2 tank for US$126 plus $29 for the N2.

I'm lazy. Will probably get the max fog set up

 

[MG_39]

Would this method be possible with a breathing mask? or small enclosed space roughly the size of a car?

Can anyone order their regulator? Or is there any age restrictions or something?

 

[Lilith666]

Can anyone tell me what FEN is ?

 

[TiredHorse]

If you look at the larger attachment "collar" (not sure what else to call it) on the leftside of the neck of the tank you can see it has INTERNAL threads. The Olson regulator will not connect to it without an adapter.

Good catch; I didn't spot that.

I *believe* the Hobart regulator should work with a nitrogen tank even though it's marked as an "Argon/CO2" regulator although I can't say with total certainty because it's been awhile since I last read up on the inert gas method.

The threads on Ar and N2 cylinders are the same. I have an Ar/CO2 regulator (Harbor Freight) on my N2 tank (AirGas).

The only known complication with using an Ar/CO2 regulator on an N2 cylinder is that --as has been discussed somewhere around the forum-- N2 is a different density than Ar or CO2, and thus the flowmeter will not register precisely. Complicating matters, no two regulators have the same mechanism, so there is no one conversion factor to use to determine indicated flow vs. actual flow --i.e. dialing in 17 LPM on an Ar regulator = 15 LPM of N2. Very inconvenient. The established workaround seems to be to nudge the flow up a bit, say to 17 or 19 LPM, to be sure there's enough N2 flowing to flush away the exhaled CO2.

How much does this method cost

Nitro canister in US $95; Make your own bag $20ish; Regulator $35

My 40cf cylinder was closer to $110, and the cheap regulators seem to have increased in price to $70. I don't think my bag cost even $10, though.

[HopelessFashionista]

I was on Instrument Depot's website and it looks like they offer shipping of filled tanks. But I don't know very much at all about what the descriptions mean or what size tank to order (or two?). They offer regulators, too, but I wish they had a link that said, "If you buy this tank, you want this regulator" so I make sure to get the correct equipment.

I like the idea of shipping the tanks to me because for some reason I'm too scared to go to a place in person. I don't know why.

It obviously costs more to have it shipped but if money isn't as much of a factor, it could be a good option. ?? Any thoughts?

I'm not going to spoon feed you with information how to ctb with inert gas, because I don't feel comfortable helping others ctb. But when I see someone might do a mistake which could result in brain damage, I have to give a warning.
The largest tube there is to small. (1.29L/105L compressed gas)

I mistook this forum as a place to seek advice and insight. Which doesn't have to be synonymous with "spoon feeding" people information. I was just asking if anyone would like to offer any feedback, such as your last two sentences.

Thanks.

 

[attribute-level-kale]

If you are using a C02/Argon regulator the flow rate should be at least 22 L / min.

I see repeated unsourced claims about the flow rate ratio being 1.44 and this is probably correct given the density.

It isn't as simple as that. Someone here did a test a few months ago: the ratio varies wildly depending on the manufacturer of the regulator.

 

[Righttodie]

So this is my go to method now.
I gave up on hanging, too much worries of it being painful.

I want to thank @TiredHorse for their great work here in informing others of this method, it will surely help others achieve an end with less worries of suffering which comes with other methods

I will be updating everyone on where I stand in gathering supplies and the cost and any other queries.
Might help others who have similar questions.

So I have started today by finally calling up the gas suppliers and one of them sent me a photo of a tank he has. It looks rusty and that's just one of my worries if it will account for any issues or not (Will it ? ). I asked for a new one, but he said it will come in bulk and not anytime soon, and I am guessing that most of the tanks these suppliers have will look a bit rough around the edges even if it may or may not make a difference.

It's about 8 months old. Total cost of the tank and gas shouldn't be more than 100 $
It is 1.5 cubic metres(53 cubic feet), the smallest most of suppliers have. The next size is 7 cubic metres, which is too large for this purpose.

You guys can let me know if this seems fine. Would be much appreciated as I would stop worrying and be reassured.
I will then be looking into regulators and other tools.

Thanks

I have seen tanks that look 100 times worse than that, in use everyday in industry. Most important is that the valve does not leak, which will cause you to lose gas, and it adds up quickly. Sadly, you just can't look at a valve and tell if it leaks.

Hey. Thanks for replying.

I guess I will check with him about any possibility of it leaking.
Is there something we can use to test the leak ?
