Help CO2 bag via baking soda & vinegar? In a bag… would this be quick and painless-ish?

I presume, that might work with relatively small bags, but pumping relatively large volumes of gas (like 15 liters or more) from one bag to another could be quite challenging, considering that you have to do this procedure while having a bag on the head and holding breath (in order to avoid premature LOC before sealing is done). I thought about this method before, and it seems unnecessarily complicated for me.

If it seems unnecessarily complicated for you, how do I do it with a large bag without having to hold breath, and without it being complicated, thank you

Holding breath is needed in either case. In the simplest method, breathing is paused for the period of placing the bag over the head and sealing it around the neck. It makes sense to use hyperventilation beforehand for increasing available time without the symptoms of hypercapnia . The prefilled bag is opened when it touches the head and is put on by sliding over the hair and skin. This step may be trained with plain air. Placing a bag over the head takes less than 5 seconds. Sealing a bag around the neck with a PVC tape takes 20 - 30 seconds.

Pumping a gas between two bags through a straw or hose requires a good seal on both ends (otherwise a lot of useful gas may just escape into ambient atmosphere).
