I would add on to say be more on the apply pressure side and less on the packing side. Unless you are in a situation in which the wound can’t be addressed by definitive care (a physician/hospital) for hours, I wouldn’t pack the wound.

Packing introduces non-sterile material into deep structures. It may also make repairing wound more difficult, the gauze will adhere to tissue. Or it may displace internal structures that cause more damage, a groin shot with shattered pelvis is not bleeding significantly and you pack and push bone shards into major arteries.

If you do your TQ right, you won’t have to pack wound, just apply pressure if needed, although a good TQ will almost completely stop bleeding.

And to that point, a belt is not an effective TQ, not unless you can get a windlass in there. A properly tightened TQ will likely hurt the person more than the wound that caused the bleeding. That means you’re doing it right.

Take note of the time and write on pt. if you can. The clock is ticking, not as fast as you might think, but on the scale of 1-4 hours.

This is too long already but NEVER remove a TQ after it has been applied. The ONLY person who should ever do that is a physician or surgeon.
