Note that ERs and ORs are generally well lighted locations. i dare say Romania has treated victims in less well lit spots. I know I have. Being able to see is a very good idea, especially when both hands are busy, conducting an exam, staunching the flow of blood, bandaging, etc. to say nothing of CPR.

You can of course, hold the light in your mouth while doing all those activities. But it is hard to keep from drooling on the victim, and that just doesn't look good.

All in all, a headlamp makes good sense. But why should you pay attention to experienced practitioners?
