Glasgow Coma Scale

The Glasgow coma scale is used to assess patients in a coma. The initial score correlates with the severity of brain injury and prognosis. The Glasgow Coma Scale provides a score in the range 3-15; patients with scores of 3-8 are usually said to be in a coma.

For adults the scores are as follows:

Eye Opening Response Spontaneous--open with blinking at baseline 4 points
Opens to verbal command, speech, or shout 3 points
