The key to surviving a venomous snake bite is to stay calm and seek medical attention immediately. When venomous snakes bite, they inject venom (poison) into the victim. If untreated, the bites can be deadly.But if the victim quickly receives antivenom, it can prevent or reverse serious harm. You do not want to increase the circulation in the bitten area. 2  If you are with someone who is strong enough to carry you, let them carry you so that you won’t increase your circulation by walking. 3  If you have to walk, reduce your physical exertion by not carrying anything (like a hiking backpack).
