Method Cheap CO2 Aquarium Bottle and Bag

I did some further research about suicide with CO2 and I think you can CTB with it.
At i'ts best, you should get unconscious before you can recognize the CO2 gas in a small room / in the car. Therefore, I will show you 3 different cases I could find about the aftermath of the gas CO2 .


I Case
A family of 4 got accidentally unconscious because of the leaking CO2 bottle for Aquariums inside their car.
The translation of the article in English

KRIENS: Family of four almost suffocated in the Sonnenberg tunnel After Saturday shopping, a family of four is driving on the A2 motorway when carbon dioxide suddenly fills the interior of the car. Thanks to an attentive motorist, they survived.

The incident occurred at noon on Saturday, at 11.45 a.m., on the A2 motorway in Kriens. A family of four was on their way home after shopping. Shortly before the Sonnenberg tunnel entrance, the CO2 gas cylinder for the aquarium leaked after a defect, according to the Lucerne police.

The gas quickly poured out and filled the interior of the vehicle. In the middle of the tunnel, the car slowed down more and more, came to a standstill and then rolled backwards into the fast lane. For several minutes, following road users drove past the family until finally someone stopped and inquired about the occupants.

The entire family sat unconscious in the car. After the doors were opened, they gradually recovered. Two ambulances took the family to the hospital. They were unharmed. However, the family was very lucky in misfortune: According to forensic medicine, there was an extremely high risk of suffocation for the unconscious.

And this video shows the situatioin. The car was standing, the people were unconscious inside until someone opened the doors after approximentally 4 minutes. No one of them was in panic or tried to open the door while being in panic. They where just unconscious.


II Case
A family died. The mom and the two kids got murdered by the father through suffocation and then he commited suicide. This article shows what the newspaper wrote. But when you read the forensic case report about this case you can read that the family father used a 500g CO2 bottle for Aquariums, inhalation masks and a bag plus rope for himself - to murder his family and commit suicide after.


III Case
The last case is about suicide with baking soda and citirc acid.

Very interesting. I wish there were photos.

This is a CO2 death by dry ice including pictures. Dry ice is also very effective.

I get that you can, but would this be an ideal method? I thought high CO2 was what triggered an instinct to breathe and what causes a suffocation feeling. N2O sounds like a much better method because it would be able to cause low O2 without triggering a breathing reflex.

But high concentrations of CO2 can bypass the suffocating feeling though unconsciousness.
I mean a small 500g Aquarium CO2 bottle can effect a lot.

What kind of inhalation masks?

 

[theEndCH]

Something like this. You also need a pressure regulator for CO2 were you can adapt the tube.

How does that work?

The tubing for the mask is 10mm?

An industrial regulator can work with the aquarium tank, for example a 22mm valve?

I wonder what flow rate could overwhelm the hypercapnic response quickly. Mild sedation could be probably be helpful.

Basically like the exit bag method right? It sounds more complicated this way due to relying on multiple small bottles of co2. Id really recommend a tank of nitrogen or argon, this sounds like it could be full of complications.

I think its only one bottle of CO2. A pressurized 500mg canister should generate something like 250L of gas I believe.
