This video covers basics. ...child proofing and how to assess how serious the injury is and what might have caused it. Car safety, pets, stings, sunburn, heat exhaustion/stroke, cold exposure, head injuries, falls, breaks/fractures, bumps, falls, burns, electrical burns, eye injuries and nose problems.
This contains video in all the segments - it is not a sit down lecture. It gives a list of things to look for and or to do for each of the things it covers. It also gives guidelines as to when you should call your doctor or EMS (the Emergency Medical Services).
I think this video is very useful, probably more so if you watch it every now and then for a refresher. I think it was well done. You can get all this information in a book, but if you are a visual learner you might appreciate seeing it.
