This neurological scale, along with the Revised Trauma Scale, is frequently obtained upon initial presentation to a hospital. The scale is an objective way of recording the conscious state of a patient. The scale measures best eye response (E), best verbal response (V), and best motor response (M). Further information is available at Wikipedia at http://en.wikipedia.org/wiki/Glasgow_Coma_Scale. The most commonly used version of this scale is actually a modification of the original scale, and has a low score of 3, and the highest score of 15.
