Did you breath nitrogen in an enclosed environment? I think that's why pph book mentioned exit bag, so the bag is full of nitrogen, no oxygen left. If you unleash the gas in a room, and breathe in nitrogen, i don't think you'll lose consciousness because there's still more oxygen in the room than nitrogen. Correct me if i'm wrong here anyone?
Is your ear still ringing?
Correct.
The most important way to succeed with this method is to understand HOW and WHY it works.
The more you read about it, the better.
Nitrogen is NOT poisonous!
I repeat,
nitrogen is NOT poisonous!
It doesn't kill you by poisoning you.
The nitrogen does not kill you.
It is the lack of oxygen that kills you.
The nitrogen causes you to pass out so that you don't notice the lack of oxygen.
The purpose of the exit bag with gas flowing into it is to create an OXYGEN FREE atmosphere around your head.
You first push all the air out of the bag, then the gas starts to flow in.
You want to know if the small bag can be swapped for a car or small room.
Are you seeing yet why that can't work, since you now understand the gas is not poison?
All of the air would need to be somehow removed from the room for that to be effective.
No such air removing invention exists.
Releasing some nitrogen into a car or room filled with air would have no way to do anything to you. All it would do is waste perfectly good nitrogen.
SadCryingBunny has issues with nitrogen that are very atypical, I wouldn't let them worry you too much.
