Exit Bag- Technical Question

[Battered_Seoul]

Apologies if this has already been addressed, but is there any specific technical reason why the exit bag scenario is a bag enclosing the face and not a larger bag enclosing and cocooning the body?

Could Nitrogen be fed into say, a 200 L body bag, using the same underlying principles?

The bag around the face requires less nitrogen and is less expensive. Also, the key is that you want the bag to fill up with nitrogen before pulling it down around your face, so that when you breath in, you pass out quickly. You wouldn't be able to do that with a body bag, because getting in would let a lot of the nitrogen escape.

Thank you.

Hypothetically, would it be possible for a person to turn on the gas at a reasonable flow rate, feed the tube into the bag, then enter and seal the bag at the beginning of the process, waiting for the Nitrogen to build up?

I wondered if the larger space would negate the carbon dioxide build up issues.
