What is the Glasgow Coma Scale?

The Glasgow Coma Scale was described in 1974 by Graham Teasdale and Bryan Jennett as “a way to communicate about the level of consciousness of patients with an acute brain injury.” Responses to eye opening having four grades (spontaneous, to sound, to pressure, and none), verbal has five (orientated, confused, words, sounds, none), and motor has six (obey commands, localizing, normal flexion, abnormal flexion, extension, none). A total patient score of 14 (on the original scale) or 15 (on the modified schedule) indicates a healthy individual while a score of 3 indicates deep unconsciousness.
