Answer: First, remove any degris or obstructions from the wound. Quickly apply pressure to the wound using any cloth or gauze available until the bleeding stops. Try to elevate the wound, if possible. If blood comes through the cloth, do not remove the cloth. Instead leave it on the wound and add additional cloth if more is available. If possible, immediately call 911 and await help.
I hope this helps. To be clear I am not a professional but this is what I was taught to do.
