Glad you resisted the invitation for a T, although technically (and I'll bet your would be rescuers probably were oblivious to the distinction), what you apply for snakebite treatment would be a "constricting band," just enough to restrict the blood in your veins, but not enough to shut down arterial flow. What seems to work better is keeping the victim inactive and transporting ASAP to medical care. Chances of survival without any treatment at all, other than rest, are excellent, due in part, to dry bites. Honeybees kill more people in the USA than rattlesnakes and sharks combined.
