If possible, if you're not by yourself, send one person for help or to call nine one one. If you have a defribulator, go get that thing and bring it to the victim's side. Assess the situation, uh, like, are they breathing? Do they have a pulse? Uh? And then also, don't forget, while you're doing all this, keep in mind that the person's neck might need to be supported or kept at a certain straight angle.
