Would this work

[mandyjohnuk]

Don't really fancy the bag in my head anymore but was wondering if this would work connected to my Nitrogen Cylinder.
Obviously my nose would be blocked off and the mouth piece would be secured in place.
Would it still need to be 15 Lpm.
Cheers

Not sure--any chance the mask will come loose?

...jaw will drop when you go unconscious. Not a good idea. Then, there is the body movements to consider.

Please don't.
