tourniquet
A cord or constrictive band used to ↓ blood flow to 1+ extremity; tourniquets have clinical currency in ↓ the centripetal flow of toxins in snake and scorpion bites, and in ↓ the cardiac load in acute CHF, as may
occur in an acute MI, where the tourniquets are rotated, simultaneously with other emergency measures–eg, O2, lasix, nitroprusside, nitroglycerin; when used, a tourniquet should be confined to the proximal part of the extremity. Cf
Rotating tourniquet.
