[QUOTE=fcpnorman;774553]If a bite occurs:
Keep the person calm
Keep the bite location below the level of their heart
Apply a dry dressing bandage
Mark the area of the swelling with a pen to track the swelling
Apply an ice pack to help reduce pain and swelling
A constricting band can be applied above the bite sit- not a tourniquet- ( not totally proven to work).
Antihistamine may not help much- the venom from a rattlesnake is a neurotoxin, however the person may release histamines in response to the bite.
Get the patient to an emergency department as quickly as possible.
May want to check your source on the ice thing. Constricting band is not recommended as well.

Good information there on antihistamine use as well.
Do not use ice for snakebites! Ice causes the smaller blood vessels to constrict and when combined with viper venoms it can produce dramatic tissue damage. Again, better to let the swelling happen and focus on getting to a hospital.
