Forestry First Aid. Catastrophic Bleeding. How to use a CAT tourniquet.

This re-enacted training video shows how to use a CAT tourniquet. This is an essential skill for those taking part in Forestry First Aid courses, or for anyone who work with chainsaws, or work in any situation where there is an increased risk of very serious injury. Direct pressure should be your first technique used to stop catastrophic bleeding in a civilian setting. Step 1. The primary Survey is now DR (C) ABC so we will control a catastrophic bleed before moving onto airway management. Get the casualty to lie down. Step 2. Identify the site of the catastrophic bleed and apply direct pressure. Wear gloves to minimise the risk of cross infection. Step 3. Cut through clothing so that you can visualise the wound and be able to place the tourniquet 5cm above the wound, directly onto skin Step 4. The tourniquet should already be prepared for immediate use. If your CAT tourniquet is still in it's wrapper, or you're not sure watch a video on how this is done. It will save you vital seconds Step 5. Depending on the situation you are faced with, you'll either a) slip the loop of the CAT tourniquet over the end of a limb, up and past the wound by about 5-6cm. b) unthread it from the buckle, place it 5-6cm above the wound, and then rethread it through the buckle. Step 6. Using the velcro, pull the loop finger-tight. You should not be able to slide your fingers underneath the CAT tourniquet at this stage. Step 7. Twist the metal bar (aka the windlass). This will pull tight down, crushing the arteries so that no blood can flow. Bleeding stops. Slip the metal bar (windlass) into the gate, and secure with the white TIME strip. Step 8. Write the time that the tourniquet was applied onto the white TIME strip. Tourniquets work well on arm and leg injuries. Their application will cause pain, can cause nerve damage, muscle damage, and result in amputation of a limb. The loss of the limb is obviously outweighed by saving their life, but there should be a stepwise approach. Attempt direct pressure first, anmd then consider the need for haemostatic gauze or tourniquet. DO NOT use tourniquets on head, neck groin, shoulder, chest or abdominal injuries DO NOT apply the tourniquet over a joint. DO NOT slacken or remove a tourniquet. DO NOT elevate a limb which has suffered major trauma. A SECOND tourniquet can be applied if the first one fails Once catastrophic bleeding has been controlled, continue with the rest of the Primary Survey, make sure someone has called 999 or 112. Continue to monitor your patient. Finally and very importantly, keep your patient warm whilst you wait for the rescue services. Blood clotting is a chemical reaction. The blood will clot faster if the patient is warm, and blood clots that have formed will start to break down if the patient becomes cold.
