Follow these steps to provide first aid:

1. Keep the person calm. Reassure them that bites can be effectively treated in an emergency room. Restrict movement, and keep the affected area below heart level to reduce the flow of venom.

2. Remove any rings or constricting items, because the affected area may swell. Create a loose splint to help restrict movement of the area.

3. If the area of the bite begins to swell and change color, the snake was probably venomous.

4. Monitor the person's vital signs -- temperature, pulse, rate of breathing, and blood pressure -- if possible. If there are signs of shock (such as paleness), lay the person flat, raise the feet about a foot (30 centimeters), and cover the person with a blanket.

5. Get medical help right away.

6. If possible, make note of the color, shape, and size of the snake. This may help with treatment of the bite. Do not waste time hunting for the snake, and do not trap it or pick it up. If the snake is dead, be careful of the head -- a snake can actually bite (from a reflex) for several hours after it's dead.
