anyone here chose CO2 inhalation?

[curiousbeing]

I consider this method. I even made a reaction inside bottle and inhaled just a little bit. CO2 inside bottle had a very sharp sensation. like something sharp going through my nose

According to Google, high concentrations of CO2 (30% and more) may be odorless and sedative, like N2O

But I fear of inhaling high concentrations of CO2, I fear I may cripple myself while alive

Well, i'd go for something else than CO2. Why? Because our body detects suffocation via increased levels of CO2 in the bloodstream, triggering fear and fight response. So if you breathe pure CO2, your body can't expel CO2 from blood and that will be very unpleasant. That's why people use other inert gases like N2, N2O, helium or even argon. Breathing such atmosphere you can freely remove CO2 from your body but still deprive yourself of oxygen.

I can't get any of them.

Although i didn't test anything, i heard that in high concentrations of CO2, passing out may be instant and painless
CO2 is used as an anesthetic for short-term procedures, particularly in small animals like rodents and for livestock

I couldn't find anything supporting this at all. All I could find is that CO2 is useful as a monitoring agent when mixed with other gases.

From my understanding, there's no way CO2 is being given as an aesthetic in and by itself. In animals, as in people, breathing in pure CO2 is going to trigger the hypercapnic response, which wouldn't be at all useful to have happen.

Is carbon dioxide (CO2) a useful short acting anaesthetic for small laboratory animals? - PubMed

The anaesthetic effect of carbon dioxide (CO2) was investigated under predetermined exposure times in rats, mice and guinea pigs with admixture of 20% of oxygen (O2), and with 20% of ambient air in rats. In rats first symptoms (median) were detectable between 7 and 9.5 s, the induction time...

Yes, my statement is very general, but some claims / evidence do exist.

From my understanding, there's no way CO2 is being given as an aesthetic in and by itself

yes, i agree. but it doesn't mean CO2 doesn't have anesthesia properties. High concentrations raise pH levels in blood, which which create anesthetic properties.

i don't feel too well right now but when i feel well, i will share my resources about my claims
in my ctb, i plan to leave bottle lid open while i breathe CO2 inside it. some air should mix with it and CO2 shouldn't be trapped inside bottle or bottle may explode due to too much CO2

Animal physiology in this regard is a tad different. Not sure about rodents but i've heard that cats actually have mechanism monitoring not only CO2 but also oxygen levels in bloodstream hence they panic and try to escape should they encounter dangerous atmosphere.

What about including some (unpure) CO in CO2? If that works, what proportion should it be?

 

[Systemic]

Too afraid of crippling my self to be honest

 

[curiousbeing]

Yes, I fear CO2 may be dangerous. I inhaled it a bit, it was sharp. But I don't know whether I should inhale it until I lose consciousness for testing it. I fear it may cripple me

I don't know about this, I think it doesn't contain any CO
