Final answer:
Control internal bleeding in the extremities, one can apply direct pressure using hands, apply elastic bandages, or immobilize the area with a splint, with severe cases requiring prompt medical intervention.
Step-by-step explanation:
You can usually control internal bleeding into the extremities in the field simply by applying pressure, using elastic bandages, or creating a splint to immobilize the area. Hemorrhage involves loss of blood that cannot be managed by the body's hemostatic mechanisms alone. In cases of minor blood loss, the body's response includes initiating clotting processes to seal off damaged vessels and maintain blood flow.
However, severe hemorrhage often requires medical intervention to prevent shock and potential death. In the field, non-medical responders can use direct pressure to the wounded area or apply pressure bandages. Standby for emergency services and prompt medical care is crucial to managing severe bleeding and preventing complications.
