Final answer:
If the bleeding hasn't stopped, continue applying direct pressure to the wound until EMS arrives. Avoid using a tourniquet or applying a bandage without maintaining direct pressure.
Step-by-step explanation:
If you have been applying direct pressure to a wound on a person's lower back for several minutes and the bleeding hasn't stopped, it is important to continue applying direct pressure to the wound. You should not remove the pressure until EMS arrives. Applying a tourniquet or applying a bandage without maintaining direct pressure may not effectively control the bleeding. Additionally, putting the person in a recovery position is not appropriate in this situation.
It is important to remember that direct pressure is the first-line treatment for controlling bleeding. Applying firm, continuous pressure directly on the wound with a clean cloth or your hand can help reduce bleeding until professional medical help arrives.
In some cases, you may need to use a tourniquet if direct pressure alone is not stopping the bleeding, but this should be done as a last resort and under proper guidance or training.
