Final answer:
PULL-LIFT refers to the technique for applying ratchet-style tourniquets, involving pulling the strap tight and using a ratchet mechanism to further tighten and secure the tourniquet, crucial for stopping severe bleeding in an extremity.
Step-by-step explanation:
The term PULL-LIFT for ratcheting tourniquets refers to a method of operation used for certain types of tourniquets that are designed to stop severe bleeding in an extremity. The technique involves two key actions to apply the tourniquet effectively:
- PULL - The rescuer pulls on the free end of the strap to tighten the tourniquet around the injured limb.
- LIFT - The ratchet mechanism is then engaged to lift or pull up on the strap, which further tightens the tourniquet and locks it in place.
The Pull-Lift technique aims to provide a rapid and secure application of the tourniquet to achieve arterial occlusion, which is critical in a life-threatening hemorrhage. Ratcheting tourniquets are commonly used in pre-hospital and battlefield settings where quick and efficient application is necessary.
