question: Hey,  my friend cut her radial artery last night. Her dad told me it was on her forearm not her wrist. I have no idea if she's alive or dead I've tried everything to get hold of her, I'm so worried. What are the chances for dying of something like that, how deep would she have to had cut. If not what kind of long term damage could there be? How much blood would she have lost roughly, would that damage her brain? Thank you. :)
