Method Exit bag and inert gas megathread

Is my EEBD hood exhale valve broken or am I missing something ?

It was mentioned that there wouldn't be any carbon dioxide panic because all CO2 would be exiting through "exhale valve"

Nitrogen gas with EEBD hood Guide (Inert gas Method)

NITROGEN GAS WITH EEBD HOOD (INERT GAS METHOD) before I start this guide, let’s be honest this method is expensive (approximately 600 to 800 dollars)and you need minimum 1 -2 months to source the equipments and nitrogen gas cylinder. My tip for you to do it cheap, purchase the Chinese products...

I tried breathing without the tank, and air goes in and out through both exists( hose and exhale valve).
I don't understand how this is supposed to filter CO2. In my opinion, it will just accumulate because air barely comes out through the "ventilation" exit.

Curious if others know for eebd - thought the hoods work similar to eb in that gas pressure flow will also push out c02 but the ventilation exit is supposed to dramatically improve c02 outflow?

Why would you need to filter CO2 if you're breathing inert gas?

I believe they are referring to how eebd hood benefit is the co2 outflow to make potentially easier for some vs eb

Is a 10-liter nitrogen bottle with 200 bars enough to get out?

10 Liter is a very large tank. At 200 Bar it contains about 1800 Liter of Nitrogen, that's over 4 times the amount needed to CTB according to the PPH.
Don't completely trust my calculations though, I'm not a chemist.

my source is an 8 liter bottle at 150 bars, suppose it is ok for the scuba method

That should be roughly 1100 liter. The PPH states you need 400 Liter for constant 15 Liter/Minute flow. I suppose scuba would needs even less than that. Just make sure to make your own calculations as I am not a chemist.

Ok thanks, anyway with the regulator the pressure will be reduced automatically. So 8l 150bars will be more than enough for the scuba method, I hope.

Only asking as someone who was thinking SCBA but now not sure, what about concerns over not having air tight seal when face relaxes? Thought that was a risk with SCUBA, someone else reminded me it is also with SCBA (eg PPH advised against masks), but seen others here appear to do the SCBA/SCBUA methods...

I use a CPAP machine at night and am wondering about options to use that, since I'm so used to it and have years of good feedback that the seal of the mask is good. It seems like it would work well, since it is forcing air into your lungs under pressure and the mask has built in venting for exhaling.

I was thinking about using a smallish, airtight plastic container to hold the CPAP machine. Then, turn on the cylinder and let the plastic box fill with inert gas for a minute or two before putting on the CPAP mask. I would also leave the cylinder open to ensure a steady supply continues. That would ensure that the CPAP is only pushing the inert gas through the mask. I would obviously need to make holes in the container for the CPAP power cord, CPAP tube, and tube from the cylinder to fill it with inert gas. Or, given that nitrogen is lighter than air, I should theoretically be able to position the CPAP so that it is near the top of the container. Then, the holes could be on the bottom and being airtight wouldn't be as big of an issue. Given that the seal between box and lid isn't guaranteed to be airtight, I could even place the plastic box upside down and have all the holes be through the lid, which is now the bottom.

What could cause this method to be ineffective?

Thanks!

Earlier in this thread (you should have search ability soon with more posts - off topic games can help) peeps reported CPAP and rebreather devices as not successful

It's exit bag (eb), emergency escape breathing device (eebd) hood, or scba/scuba but PPH only recommends eb & eebd hood

Thanks for the tip about how to get search functionality. I read quite a bit of this thread, but it's too long to read everything.

What do you guys think is more effective? Eebd hood or regular exit bag?

The scuba method is with a full face diving mask. I find this method so much simpler and safer than with a bag.. But this is a personal criticism.

If you want more information, there is the guide and megathread of the user "befree" on the scuba method. It is well explained.

totally relate - I'm thinking scba is a bit easier even (1 fewer adapter piece) per GasMonkey Setup thread and the positive pressure seems to mitigate risk of mask setup warned by PPH (but scuba may be easier to source and less costly)

however not at expert - just spent too much time going thru all the diff threads T_T

 

[NitrogenAfternoon]

My first post, please excuse me if this is not the way to ask, but this is the method that has always spoke to me, and my preferred one. What would happen if there was no exit bag, just my 20L dewar with the N2 and my car. If i just simply opened the lock cover and removed the neck plug of the 20L dewar while in my car, would this end up doing anything at all?

After doing some more reading, I think I figured out the issues with what I described.

First, even assuming that the mask doesn't let anything in that isn't supplied by the CPAP, a lot of air being sent by the CPAP will leak through the exhale vent holes. This would require a lot more inert gas at a much higher rate, meaning you'd need a much bigger tank.

Second, you need to be concerned about the rate at which the CPAP sends air out of the container and match that rate coming in from the tank. If you aren't supplying enough inert gas, air from outside the container would be sucked into the container through any holes that aren't airtight. Or if the holes are all airtight, it would affect the ability of the CPAP to continue pushing air because you'd essentially be trying to create a vacuum within the container.

The air we breathe is 70 something % nitrogen. Is it possible to do any chemistry to remove the 21% oxygen and use that as the nitrogen cylinder?

Probably a silly question but doesnt hurt to ask, eh?

Sure, you can purchase a nitrogen generator but they aren't cheap, they start at around $2,000.

Alternatively you can buy a rebreather that removes the CO2 from the air as you keep breathing the same air over and over again, leaving nitrogen. Someone was selling a rebreather here a while ago, but it didn't work well and they eventually disappeared.

 

[Fire&Ash]

Has no one put a video up from beginning of setting up the tank and regulators and also making the bags and connecting it? Also I don't understand removing the oxygen before releasing the nitrogen. If you remove the oxygen won't you suffocate? Am I misunderstanding that?

The pain response occurs from CO2, not from lack of oxygen. There should be no pain unless there is CO2, which is produced from respiring oxygen. Thats how inert gas works, an atmosphere without CO2 or oxygen.

Can anyone find the archive of the doing with chi video? If one still exists? Or whatever the video was called

[Loaf of bread]

There was an old inert gas setup video, called "doing it with chi" or "doing it with betty" (I forgot). It was taken down at some point, I am not sure if any archives exist. If there are, please share

Can someone answer this? From my understanding, if I got a big plastic bag, those large turkey ones, and tapes the plastic tubing to the inside, is that the proper way? Also, trying to push oxygen out before putting bag on doesn't make sense to me? If I put the bag on my forehead, wait for the nitrogen to fill the bag up, and then pull down the bag on my head, is the oxygen gone and I did the method right? This is how I'm visualizing it but I don't this is right? I'm just stumped on removing the oxygen and then adding the nitrogen because I think if I just put the bag on and add nitrogen, I would start freaking out from the mix of both right?

The idea behind it is to create an oxygen free environment using the pressure from inflowing inert gas.

By using an elastic cord snug (but not sealed) and smushing out the air first, one can see the nitrogen filling up the bag and know it's ready to be pulled down; there may still be traces of o2 from pulling down over face to neck, but should be forced about quickly by the gas with any co2 exhaled until gas runs out.

I think this person spells it out clearly:

Hello everyone. I am having the worst time trying to find a regulator and flow meter. I know I can use argon/co regulator but it usually comes with 2 gauges. Which I'm not sure if I want that? And I can't find a proper flow meter. I have not found one flow meter that uses lpm on Amazon. I also don't know how I would combine these two things together to the cylinder. My original plan was to get a combined one but the units were not right. Help? Where did you get yours? Will you chat/conversation it with me?

 

[parasite_eve]

On regulators/ flow meters:

1. There should be two guages on a 2-in-1 regulator/ flowmeter: one showing pressure (how much you have left in the tank) and one showing flow rate (what we need to set to 15-19 LPM per PPH).

2. Many come with CFH instead of LPM but this can be converted using algebra or finding online converter site (DO NOT use GenAI).

3. I found options by searching (argon click style regulator) because I like how these can just be set easily to a certain flow rate 0-60 CFH for argon (0 to ~34 LPM for nitrogen). But also check out this for alt style and details on how to do the calculations:

Just finished putting together a nitrogen exit bag setup

I just thought I'd share a description of the gear I put together for inert gas asphyxiation with nitrogen and an exit bag. It's pretty basic since I felt it would be better to start with something simple and functional, then upgrade to SCBA/SCUBA or something else in the future if I have time...

Ya I've been looking for one through Amazon and Airgas. Idk. I just see regulators with 2 pressure gauges (low-high) but no flow meter. I did find one with one pressure gauge with a glass tube flow meter but the flow meter is not right.

Are you in the US? Regulators vary a bit in different parts of the world due to different units and standards for fittings.

When I search Amazon for argon regulators in the US I'm getting around 10 suitable results ranging from $20 to $150 in price. Thet all look similar to this:

Alternatively you could get a 2-gauge pressure regulator along with a separate nitrogen flow meter. You would have to connect the regulators together and set the pressure regulator to produce the output pressure needed by the flow regulator (50 psi I believe). The advantage is you could get a nitrogen flow meter instead of argon and eliminate the need for unit conversions.
