Perform the simple following actions if a snake bites you or a friend -
1. Remain calm.
2. Immobilise the bitten arm or leg, and stay as quiet as possible to keep the poison from spreading through your body.
3. Remove any jewelry before you start to swell.
4. Position yourself, if possible, so that the bite is at or below the level of your heart.
5. Cleanse the wound, but don't flush it with water, and cover it with a clean, dry dressing.
6. Apply a splint to reduce movement of the affected area, but keep it loose enough so as not to restrict blood flow.
7. Don't use a tourniquet or apply ice.
8. Don't cut the wound or attempt to remove the venom.
9. Don't drink caffeine or alcohol.
10. Don't try to trace or capture the snake, but try to remember its color and shape so you can describe it, which will help you in your treatment.
11. Seek immediate medical attention!
Note-This is not a treatment,this is just a first thing to do... The last one which is No 11 is your treatment!
