Please note: If a person is unconsious because of a severe trauma such as a car accident or a sports accident, to decrease the risk of spinal injury, move the head, shoulders and back as one unit if you have the proper training. Do not attempt to move the person if you have no prior experience, as you may cause him more injury! It works best when two people move the victim in tandem, with one person holding the head and shoulders steady and the other helping to roll the victim over. Also, not only does this side position prevent suffocation due to blood in the lungs, aspiration, etc. it also makes it easier for paramedics to place a neck brace and backboard on the person when they arrive.
