I’ve not yet had a snakebite patient, but what little I’ve read on the matter is to not try to evacuate the venom, and do not place a tourniquet. Do not apply ice either. Keep the extremity still and relaxed and in a low hanging position. Maybe consider splinting the extremity so as to keep it immobilized. Movement makes blood and lymph flow.
Semper Fi,
