Method SN risk of long lasting side effects in case of failure

[Topaz111]

I've read somewhere here that SN has relatively low risk of long term side effects in cases of failed attempts, but I'm kinda confused about it?
SN causes death due to hypoxia right? But so does hanging and strangulation, so why is SN lower risk? From what I understand hanging and strangulation causes hypoxia due to physically cutting off blood flow to the brain by compressing the carotid arteries whereas SN causes hypoxia due to chemically altering your blood's ability to give oxygen to your tissues.
However, in both cases the result is the same, no oxygen to the brain. When brain has no oxygen the neurons begin to die which can cause brain damage if someone is "saved".
So why would the risk of brain damage from SN be lower than that of other hypoxia methods?
Am I missing something?

Yeah, I don't understand that either. SN is basically liquid Carbon Monoxide, which in itself can have massive failure repercussions.

From my understanding, SN is lethal even if you just take a little, and rescuing is rather hard. Giving you concentrated oxygen does not help much because the iron ions in your blood are oxidised. (The medics would probably know what is wrong when they see you, Still, methylene blue, the substance used to cure it, is not very accessible.)
Yet failures can happen, and in those cases, things wouldn't be too good. This is probably the part I fear most since I live in a place where people give way to ambulances (which is normally a good thing lol)

how come it was a failed attempt?

how come it was a failed attempt?

I had intensive medical care. I had a cardiac arrest and was in a coma for a little while. They could have called my death at any moment, but for some reason, they didn't.

My understanding is, if they want to save someone, they have to do so before the hypoxia has reached a certain threshold. Beyond a certain point, despite the best efforts, the person can't be saved and the doctors would know that.

SN is pretty fast acting like 40 mins at the standard dosage, I believe. That leaves a pretty short window for the critical threshold to be crossed. The way I see it, it is that it is like a switch. Either one makes it through or doesn't - with no major problems, being free to try again. That is what makes the method preferable, I believe, for a lot of people.
