Woft,<br><br>I'm sure the MDs on the forum will weigh in on this, but the latest I heard was that tourniquets are used only in the case of SEVERE bleeding, such as an accidental amputation or severed major blood vessel on an extremity. Tourniquets are no longer reccomended for snake bite treatment, in fact it is reccomended that they not be used. Treatment nowadays is to treat for bleeding at wound site, potential shock and evacuate patient to medical facility post haste. The Sawyer Extractor is the only viable field treatment even seriously discussed. <br><br> Hope this helps. Trust any advice from the medical people on the forum over mine, but the info I provided was the latest I'm aware of.<br><br><br>Take care,<br><br>Andy
