Method Homemade Debreather System. Would this work?

[social_anxiety_sucks]

Homemade Debreather System - I don't know if this works or not. It was just an idea I had after reading this thread.

The working principle of a debreather is simple. It's a closed-circuit breathing system used in inhalation anesthesia. If you don't understand it, there are lots of trheads to learn about it. To make this debreather, one needs a tiny closed space -the smaller the better-, an air pump, PVC pipe and conections, carbon dioxide absorbent (soda lime) and silicone or other material for air insulation. As in the picture, the air pump sucks the air from the box and sends it to the "yellow" pipe filled with soda lime. The soda lime then absorbs the CO2. The carbon dioxide free air returns to the box again. As one breathes the O2 and CO2 in the box will continuously decrease. Only Nitrogen remains.The important point is a good air insulation.

What do you think about that?

I'm no expert by any means, but it at least aesthetically seems more comfortable and peaceful than in other methods

Yes. Also depending on the air pump there would be less noise.

I think the most difficult aspect is to buy soda lime. As far as I know it's legal to buy, but is not of common use

Look for Sofnolime.

Maybe 6months ago while i still had a roof under my tired bones i tried a cringe thingy. I was under my bed and there is no way how air can get in. I was there like 1hour till i couldnt breathe anymore and it was so hot in there.. i felt the strongest SI of my life back then. Debreather sounds fun but in reality..

Can you explain better what debreather did you use? Were you using the RD2 ReBreather?

 

[albino_elk]

Nono i didint used any debreathers but im saying SI is hard when You have no air lefr to breath

The debreather gets rid of CO2 until there's just nitrogen left, so there shouldn't be a panic response.

Little improvement. The CO2 absorbent can be placed inside the box. Only two points will need air insulation (the pump wire and the neck).

 

[Choronzon]

Seems like you could just use a couple of one-way valves, and then you don't have to have a pump, and therefore don't need to insulate another hole.

That's true. But in this design I wanted to rely on a pump to force the air through the canister. I believe it's easier to breathe if a person don't have to put on a mask

Should work. Pipes could be insulated at the holes with caulking

Based on your schematic, you would require at least a degree of magnitude higher flow rate to properly fill the enclosure with nitrogen; otherwise, the individual would have to time wait a long time and/or suffocated from the CO2 buildup.

Just my €0.02...
using this setup means you create a room that is devoid of oxygen. You're putting who ever finds you at serious risk of asphyxiation and death.

Is this true? I thought it was just the space in the box that was doing this.

How so? The space devoid of oxygen is only within the box. Moreover, the limited amount of soda-lime will only absorb CO2 and not oxygen.

Greenberg, what do you think of this powered homemade setup

 

[JustLosingMyself]

My bad, didn't read the schematic right.

Your head is in the box.

How rigid are the walls of the box?
It needs to be able to expand and contract with your breathing or the physics won't work.
If it can't do that the air you exhale creates an over pressure in the box that will escape at its weakest point. Then you need to breathe in, reverse problem: fresh air will come in negating the CO2scrubber. You need a counterlung (something that can expand and contract freely as you breathe) somewhere to allow for the volume change.
If the air you exhale can't escape, you will not be able to breathe at all quite quickly as your diaphragm muscles tire out.

i actually think that it is an improvement as it is powered. however, the container is quite large and would require time to fully deplete all the oxygen.

Does the extra time mean that you will be suffering? How fast does oxygen have to drop not to suffer?

The real suffering is not from lack of oxygen, but too much CO2. As long as the soda lime is absorbing enough CO2, it would be lights out quite rapidly.

From everything I have read, the big concern with using a debreather is that doing it solo, you may dislodge the mask. This version uses a box that encases the entire head, which would help with that, though of course there is then the issue of the seal about your neck.
