More nitrogen questions - sorry!

[Noone]

How tight should the bag be over your head before pulling it down? I know it shouldn't be airtight but I need to know exactly how tight it should be around the head. Does the elasticity of the cord take care of that? Also according to the handbook it calls for 10mm (width) elastic cord. What if there's only something like 4mm (width) cord. Is that still sufficient? It seems like the thicker the cord the less stretchy it would be. I'm just musing as it ironically helps me feel better. Any serious answers are appreciated.

I also had some question about how tight the bag should be; constructing one and actually trying it on addressed that for me. Getting a feel for it helped.

I used 3/8" (9.55mm) elastic and it was fine; the thickness of the cord does not affect its elasticity.

In the Nurse Betty and Chi videos, where they are making a bag, it looks like they are using cord that is smaller than 10mm, it looks like a drawstring that you'd see in a hoodie or men's swim trunks.

Thanks for answering; anyone else have any other answers also?

Not too tight if you're planning to flush it with constant flow of nitro.

Actually, mild hypoxia is quite pleasant and should be experimented with until perfection.
One can simply hold the bag's mouth under his chin, while sitting on the beds edge, and if you faint, all muscles will relax and you'd involuntarily release the grip and get back.

But wouldn't that involve using multiple tanks? I would imagine that'd be a lot of money. Can one practice without a tank?

I have to remake my bag again. The borderline personality disorder sort of made me make an impulsive decision to get rid of part of my suicide kit awhile back. I had temporary shift swing back to try living and was concerned about hiding my gear so I got rid of a few things lol! Ugh! Well now I have to make the bag again and yea fun fun. Preparing this again sucks, thank god I kept the wrench to tighten the meter thing to the cylinder, the regulator or meter, and hose. I'm paranoid that someone is going to try to stop me from following through with ctb and trying to get this goin and planned. I'm still debating wether to get a motel room or do it in car. It's really getting down to I need to do this and soon. I just don't want to keep existing in my very sad life I'm leading. It makes me tear up though when I think about dying alone in some shit hole apartment, motel or in car by myself. I did imagine as a young person that I might have a very sad lonely death. Self fulfilling prophecy.

Don't apologize for asking questions and thank you for posting these. I can't help you with the bag, but there was a case report of a 29 year old man who used nitrogen with a full face scuba diving mask and he was successful. Maybe you could look into that as well? You can get some inexpensive ones.

I used ~1/4" elastic on my bag, with a plastic cord-lock to hold it tight. I didn't cinch it especially tight --it was easy to put my fingers under the elastic-- and the hose ran up my back, under the cord, and to the hair elastic at the nape of my braid (very convenient place to secure the end of the hose). In a few shallow breaths my hands got tingly (despite mental preparation I couldn't bring myself to breathe slow and deep); and a few more, I started to get lightheaded. I'm confident that with the good flow rate I had --15Lpm-- any gas escaping past the elastic would have helped clear my exhaled CO2 (a good thing) and been immediately replaced with fresh N2.

I flubbed it (obviously), but that was me chickening out, not an equipment/method failure, and I have left the bag adjusted as I had it for my next attempt.

The description I read somewhere, that I was using for guidance, is that it should be like a shower cap. The elastic drawcord felt very snug when it was around my brow, as I was waiting for the bag to inflate with N2 --a little bit uncomfortably/pinchy-- but that became a fairly gentle seal when I pulled the bag down and settled it around my neck.

The sources say It has not to be tight, but rather loose; the reason for that is allowing nitrogen to flow and flush CO2 from the bag. Flushing CO2 which we exhale is crucial for peaceful exit.

I just bought 2 tanks that can hold nitrogen, 22cf is the size or capacity I guess, I got them at a brewery supply store, but they didnt fill them up there. All the air supply stores are closed today, bummer. It was $84 each tank empty. I got the regulator for $26 @ Harbor Freight, they gave me 20% discount off because their cc machine was down, off of $32. It fits these tanks. The brewery estimated it is $45ish to fill each tank at air supply. They brewery supply had plastic tube hoses for cheap, I havent tested anything yet. I didnt make the bag yet, but I am using a turkey brine bag from bed, bath, beyond, tape, cord I will take from a hoodie or something I own, and I got some toggles from Joannes Fabric, $3.99 for 2pk. I was hoping to do it today, but no air supply, now idk where I will hide the tanks at home :/ . Also, as others have stated, idk if I will do this at a rental place, or in a car...I am also hoping it will be painless and successful...

So long as the regulator fits your tanks --nice score, getting it for cheap!-- you should be darn near ready to ctb. The rest --filling the tanks, constructing the bag, hooking up the tubing-- is easy.

I don't think you'll be able to use both tanks at once with that regulator, but a single 22cf tank is ~623L, so with a flow rate of 15Lpm, you should have 41 minutes of N2. So long as your eb doesn't leak, that should be plenty of time to ctb.

I used a turkey oven bag, from the supermarket, but I expect a brine bag may be just as effective...? I'm a vegetarian, so I know nothing at all about how to cook turkeys!

Make sure you use an elastic cord on the eb, if possible. You want the flow of nitrogen to be able to escape, taking the CO2 from your respirations with it. If you use a non-elastic cord, you'll need to be careful not to jerk it too tight for the extra gas to escape.

Wherever you decide to ctb, make sure you can sit up so that the bag stays on your head. If you lie down, and you twitch while you're going under, you could displace the bag and miss the bus.
