Educational Pearls:

What can you do to control bleeding in a penetrating wound?

How do you build a compression dressing?

Think about building an upside-down pyramid with the gauze.
Consider coagulation agents such as an absorbent gelatin sponge material, microporous polysaccharide hemispheres, oxidized cellulose, fibrin sealants, topical thrombin, or tranexamic acid.

What are the indications to use a tourniquet?

The Stop The Bleed campaign recommends looking for the following features of “life-threatening” bleeding.

How do you put on a tourniquet?

If using a Combat Application Tourniquet (C-A-T) tourniquet, apply it proximal to the wound, then rotate the plastic rod until the bleeding stops. Then secure the plastic rod with a clip and make sure the Velcro is in place.
Mark the time - generally, there is a spot on the tourniquet to write.
Have a plan for the next steps. Does the patient need emergent surgery? Do they need to be transfered?

How long can you leave a tourniquet on?

What are the risks?
