You are both looking at it the wrong way. The bar-graph represents the procedure, not the patients' status. Think of it this way, you come to an unconscious soldier with a stopped heart and you try to bring him up. You try for two minutes and IF he doesn't regain consciousness, you declare him as dead and move on.
And about randomness, you can get a bullet to your thigh and it might end up in you heart in real life, and we don't expect Arma to simulate all the conditions that control the bullet travel through the organs and affect of bones and tissues on its route so I'm perfectly ok with the current level of randomness this Psycho's setting provides. Also, you might died instantly if the injury is severe enough.
