1 - Sit or lie the casualty down
2 - Check the wound for any stuck objects
3 - Apply direct pressure with some clean material for 10 minutes to allow clotting (tea towel, muslin, spare t-shirt etc.)
4 - Apply a sterile wound dressing
5 - If blood comes through it, apply another one on top and more pressure
6 - If blood comes through the second one, take both off and start again
7 - If it doesn't stop then take them to A&E
For years we also taught to elevate the wound but recent studies have shown that doesn't actually make any difference. However I would still support the limb in a comfortable position and that may well be slightly elevated but not at the expense of direct pressure.
I can now also teach a course on catastrophic bleeds including the use of tourniquets and haemostatic dressings for anyone working in hazardous environments.
