make a fully sealed tent for nitrogen method

[Rose57]

Is there a way to create a fully sealed tent for the nitrogen gas method? Or maybe use a body bag ? I'd like to be able to ctb with another person at the same time so thought a tent would be ideal. I guess it could work if we both use exit bags just on our heads too. It would just feel more intimate and less scary to simply hop in a tent with someone though so am wondering if this is possible.

Getting the oxygen out of the tent would be very difficult, and you'd put whoever found you at some degree of risk with a tent.
