🔺  Sit or lie the casualty down
🔺  Check the wound for any stuck objects
🔺  Apply direct pressure with some clean material for 10 minutes to allow clotting (tea towel, muslin, spare t-shirt etc.)
🔺  Apply a sterile wound dressing
🔺  If blood comes through it, apply another one on top and more pressure
🔺  If blood comes through the second one, take both off and start again
🔺  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.
