Brachial artery gunshot wound

I attended a multiple shooting as part of an ambulance crew a few months ago in xxx City and whilst treating a GSW victim, a colleague shouted to me he couldn’t control the bleeding on another victim, which was a brachial artery bleed from a shotgun. We packed the wound out with Celox Gauze, applied direct pressure and then wrapped it with an elastic bandage.

The bleeding arrested within 2 minutes and the guys were gobsmacked. I spent the next 30 minutes trying to explain to the hospital staff all about modern haemostatics!
