I'll comment on the wound that isnt bleeding out.

You will be stunned and fearful of treating that wound,but if you have no choice,you have no choice.

I wont go into what to clean with,you will use what you have.Just get it as clean or sterile as you can throughout treatment.

Use common sense to clean wound and keep clean as best you can.

A wet packing,not dripping wet but moist enough that it isnt dripping,and covered with a dry dressing will work in that situation.Change daily.Protect both victim and yourself from wound and infection,that means gloves if you have em.

As long as victim agrees that what you are going to do isnt the optimal,but the best you have,and is willing to accept the risk,then you just buck up and do it.

BTDT one time,dont want to do again,wound healed but......not a good thing to deal with.
