Rebreathing mask

I have been into hoods for years and now my focus has aimed on rebreathing masks (one of those hoods with a rebreathing bag attached). But since I haven't tried I am curious of the feeling it gets to the user. How does it work, how long are they used, buying one, what should a first time user be aware off?

HA!

You need to be with someone you implicitly trust with your life and who can handle life-threatening emergencies if you fuck up.

The length of time you can use a rebreathing bag varies with YOUR size and the size of the bag. At first you will feel nothing, in a little while, it will feel kind of like breathing in bed under a heavy blanket, later you will start to feel short of breath, later you will feel a little light headed and your ears may begin to ring, then you will feel increasingly light headed until you pass out. Hopefully, you will be released before you die.

You may in earlier stages feel agitated and vigorously try to get out of your apparatus, especially if you are restrained while using the rebreathing bag.

Your partner could accidentally or purposely kill you or unknowingly allow you to die.

Thanks for your reply, it sure gave something to think about.

In some of the videos they ware them for a "long time", hopefully they know what they are doing. I am not scarred yet, I still want to try, small steps will be the way.

Don't the bag have a small hole to let some fresh air in? What would be the best setup?
