Trauma victims need emergency blankets.
If you get cold (even a few degrees colder than normal), the consistency of your blood begins to change; it doesn't flow well, it doesn't clot right, and most importantly it doesn't transport oxygen efficiently. This is detrimental to someone who already lost a lot of blood and is why emergency blankets, used to prevent hypothermia, are considered high priority for trauma victims.
Trauma victims don't always realize that they're getting cold (or even that they're a trauma patient!).
Traumatic injuries are almost always unexpected, and the attention of the victim is usually directed at a) trying not to get injured again and b) the actual site of the injury. Consequently, a victim won't notice that they are getting cold (which might be why hypothermia has been called the silent killer). If you've seen photos from the aftermath of mass-casualty events (such as the Paris terror attacks), you've probably seen people walking around draped with the metallic-looking blankets. Professional responders know that victims don't realize when they are getting cold, and will often take steps to prevent hypothermia - just in case.
By preparing for the unexpected with emergency blankets, you can save lives while an ambulance is en route.
