Elevate the wounded part of the body with some wadded cloth or even your lap, cover it up with gauze and wrap it tightly, before moving the patient to a clean place, and monitor them.

[then nehan raises a finger. he has to make this important point, and waits for silence just in case flynn wants to ask something.]

But make sure you keep the pressure for at least fifteen minutes, and resist the urge to pick at the gauze to look underneath. If blood soaks through the gauze, add another layer and restart your count.

This will take you out of the fighting for a while-- this is why medics aren't often warriors as well. [except for nehan. nehan knows how to be an exception.]
