I stumbled upon chronicpainnomore's excellent list to assemble a DIY exit bag and nitrogen kit.
It seems that the whole idea of the exit bag, as I understand it so far, is to allow the nitrogen to flow into the exit bag at a fixed rate while it's fastened around your head. In addition, the inward flowing nitrogen pushes out the CO2, which escapes at the fastening point where the bag is secured by elastic at your neck. This is a critical point because if CO2 builds up without flowing out, your body has a natural mechanism to detect CO2 buildup (but not nitrogen buildup) and trigger some kind of nervous reflexive response to get you back in action and get the CO2 out of your lungs through coughing or whatever.
But the part that troubles me is how am I supposed to secure the exit bag well enough that the nitrogen stays in but not so securely that the CO2 can't exit the bag?
I wish I could purchase a pre-made one but it seems that anyone who tried to sell pre-made exit bag/kits in the US were arrested for it. Even if I bought one I wouldn't be sure how to fasten it.
The technicalities of the inert gas method are what made me want to go with N for the longest time. But since I didn't purchase N a decade ago when I had easy access to it, hypoxia seems like the most painless and sure alternative. But the idea of getting one of these details not quite right and ending up with brain damage, scares the hell out of me. Besides the CO2 flow issue, there's the possibility that I could slump when I lose consciousness and my body could disconnect the tube from the regulator while I am only unconscious but not fully decommissioned.
Are there any guides that spell out the precise details of how to ensure none of these things have any room for error? I read PPEH Chapter 5 but it didn't resolve these questions. Are there are other guides that are more comprehensive on this method?
