Long time ago I have seen self harm video where the person sticked a thick syringe needle in their arm (on the front part of the elbow where doctors usualy take blood) and was letting out blood trough it. The video didnt go on for long but the blood was flowing out surprisingly fast. They wrote that they planned to let it flow till they get light headed so i was wondering if it would be possible to actually cbt like that? If you laid on the bed and hanged your arm down? Do these smaller artheries clog up after certain time and stop the flow? Or maybe trying to stick the needle in some other bigger arthery?

im no expert but from what i know exsanguination is not a good way to ctb, its painfully slow, and hypovolemic shock doesnt start setting in until youve lost about 20% of your blood supply, bleeding out has a very high survival rate, just not worth the risk imo

There's no reason why it wouldn't be perfectly possible, I read about it a lot as it was a preferred method for me for a while after I realised how close I got to dying


I used to use a large gauge cannula,
With a 14g cannula the blood pours out of the cannula (if sited right) I would lose 500mls in less than 5 minutes.
The bottom line is an average person has 4.5 to 5.5litres of blood in their body.
You'll feel dizzy, faint hot, then palpitations, anxious but at a loss of 2litres + you'll have a significantly reduced GCS and will no longer be aware of what's going on and fast approaching death from hypovolaemic shock/ exsanguination.

The smaller the cannula you use, the longer it will take and the longer you'll have to endure the side effects

I fainted right after I donated blood, there might be ways to encourage it.

I wonder if blood thinners would help or even beta blockers to interfere with shock? Just thinking aloud here.

Seems like you might get confused and interfere at some point, I guess you could use heavy tape to hold it in place.

Thank you for all the information
