South Dakota EMS Protocols Practice Exam

In mass casualty scenarios, stopping life-threatening limb bleeding as quickly as possible is the top priority. A tourniquet can be applied immediately to an injured extremity to control arterial hemorrhage, without waiting to apply direct pressure first. This approach minimizes blood loss and buys time for more patients to receive care. Direct pressure remains useful and can be applied if feasible, but it should not delay the tourniquet when rapid hemorrhage control is needed. If bleeding continues after applying a tourniquet, reassess and manage per protocol, but do not delay tourniquet use to attempt direct pressure first. Tourniquets are appropriate in the field for severe limb bleeding and are not saved only for hospital arrival, and they are not contraindicated in MCIs.
