dry ice as a method?

[lsdycion]

i recently read a novel where a character commits suicide by locking herself in a bathroom with dry ice and laying on the floor; the dry ice melted and the cool carbon dioxide fell to the bottom, suffocating her. any opinions on this as a method? any research or real-life examples of this?

You would have to seal the room to make sure the CO2 stayed in it. Tape over any doors/vents. If you share a residence with anyone else, this can pose a danger to them as well.

The biggest problem with this is that this induces panic. You body knows to take a breath if the amount of CO2 in your blood gets too high. If you fill a room with CO2, your brain will start screaming at you to breathe and eventually will push you into a panic state which will most likely lead to you just ripping the door open to get air. Death with CO2 requires either an insanely strong will to overcome instinct or something to completely knock you out so you are 100% unconscious while you die.

There have been reported deaths by CO2 vaporizing. There was a case where dry ice was thrown to a pool during a party to create a fog. The result was some swimmers died because they lost conciseness while swimming and drowned. CO2 inhalation is considered an agonizing painful way to CTB. Though breathing pure CO2 will knock you out in 10 seconds it will be very painful. Smaller concentrations might knock you out with less agony but will take longer.

It could take a day or more. Fresh air could infiltrate your space and cause a failure.
A news story years ago told of someone putting a lot on their head. Also slow but it froze their brain.

I believe that carbon dioxide poisoning is generally considered to be unpleasant. My understanding is that you feel like you're suffocating when you have too much CO2 when you inhale, not when there isn't oxygen. I believe this is why inert gases (nitrogen, helium, etc) are preferred. There probably are people who used CO2 but I think it's generally considered an unpleasant way to go.

I think it could work. Some may prefer taking a relaxant of some type while others may find they don't need that. Case in point: https://www.cnn.com/2018/08/01/health/dry-ice-death/index.html

if it is just for 10" of painfulness, it is feasible, isn't it ?

It seems to have the "easiest" and most "pleasant - read quick" experience with this method requires a nearly 100% CO2 environment. Someone might as well just buy a coffin for a container and do it in there. Kind of a "one and done".

I hadn't heard of the dry ice in the pool catastrophe. But this makes sense, at a high concentration, it kicks in right away and then if it knocks you out you go underwater and drown. I will keep this in mind the next time it's suggested at my next pool party!

Its feasible and has been successfully done before but its not a peaceful way to CTB. A lot of SI to overcome.

I gotta ask what the heck SI means because I have no idea :')

But ctb using CO2 scares me. The burning sensation and need to breathe that comes along with suffocating is the most frightening part.

A buildup of Co2 is literally the one thing our bodies make sure we deal with because it actually makes our blood acidic. The science around it is pretty cool, at least. I'm sure its something that can be overcome using external means, but its still too spooky for me.

The SI (Survival Instinct) helps keep people alive by avoiding harmful events. Basically it means a man chickens out before killing himself.
There is a scientific approach to it and how to overcome it thread:

For me no more pool parties in this life.
