Hi Starman,
The show I watched with the guy being Bit on the foot, his girlfriend put a tourniquet above his calf just below his knee, which is what I would have done!
A doctor was on the show she said that if you isolate the venom in one area then you experience more problems in a smaller area rather then let the venom travel and disperse through your body.
The girlfriend did the sucking thing on his wound, the doctor also said that was a wives tale and it has no effect. She went on to say that you want to sit still and wait for help if you can and not get your heart rate up.
Disclaimer, I no nothing about snake bites, I would have asked my girlfriend to start sucking immediately and I would have put on a tourniquet immediately.
The show is called "Something Bit Me?
