I have personally used TQ's to save Lives in Real World Applications. I would also include limbs in the statement, but you cannot always save limbs. I see a large wound with Arterial Blood Flow, Tourniquet before I even worry about Dressings.
I used to talk about this with my dad when I was a kid (he was a WWII Marine Medic). He always stressed "save the life. LATER you can worry about infection or limb damage."
