That one looks great. I like to have a little light in case I need to do first aid in the dark, not mention that patient monitoring can be a nightly affair too, and things like pupil dilation and skin tonne can be important assessment factors that are hard gauge without light. A pen light can be held in the mouth for hands free use, making it a good alternative to a headlamp IMO.

Keeping warm a patient who is in shock is something to consider. I've never really thought about not needing a blanket of some sort for that, even a Mylar one, but that could be the Canuckian in me speaking from my Northern experience. I will say this though, when I shattered my shoulder at the end of July a few years ago, I went into shock and was shivering because I was so cold, even though the temp was still in the the 30Cs. Could have been the shock, the sun exposure, or a combination.
