How do you remove the poison when a snake bites?

Immediately remove the victim from the vicinity of the snake, which could be panicked and continue to bite. Try to memorize the physical characteristics of the snake - this is important for later treatment - but don't attempt to capture the snake or kill it; you'll be no use to the victim if you too are bitten. Don't allow the victim to become panicked, keep reassuring them and keep them immobilized until you can reach medical aid. Remove items such as jewellery or well-fitting shoes, belts and so on, from the victim; these could restrict blood flow if the area swells. Apply compression to the wound site and apply reasonable pressure to the limb above the wound (most snakebites are on a limb). Bind a splint to the limb if possible, but ensure there is no tourniquet effect; you must not cut off blood flow. Continually check extremities - fingers and toes - and ensure they're still warm and mobile. If you have a phone, take advice from paramedics, calmly, while you're attending to the patient. Never interfere with the wound by cutting into it or attempting to suck out the venom. This is highly dangerous and in any case doesn't work. Never use ice or or alcohol at the wound site and never, ever, use a tourniquet. Antivenene is effective in most cases and the majority of victims recover given proper treatment. One more comment: the vast majority of people bitten by snakes are attacked in the process of attempting to kill or relocate a snake. Left alone, they'll simply go away. If they see you as an aggressor they will retaliate and who can blame them?
