From a quick look-over, this seems to be just what it says. Worth well more than the $2 pricetag. Seems to cover all the most likely kinds of trauma. But, for example, there's nothing on a stroke. Here's what you need to know for that: FAST Face Drooping on one side. Ask person to SMILE. If smile lopsided, it’s a stroke. Arm Weakness….ask person to raise both arms. If one drifts downward, it’s a stroke. Speech Difficulty….ask to repeat simple sentence like “the sky is blue”. If it’s slurred, or mis spoken, it’s a stroke. Take Action…call 911 or go immediately to ER if any of the above are evident.
