Clinical Notes

GCS is a neurological scale which aims to give a reliable and objective way of recording the conscious state of a person.
The lowest possible GCS (the sum) is 3 (deep coma or death), while the highest is 15 (fully awake person).
Report each section score individually (e.g., E4V5M6 = GCS 15).

About the Glasgow Coma Scale

The Glasgow Coma Scale (GCS) is a clinical scale used to reliably measure a person's level of consciousness after a brain injury. The GCS assesses a person based on their ability to perform eye movements, speak, and move their body. These three behaviors make up the three elements of the scale: eye, verbal, and motor.

Interpretation

Severe Head Injury: GCS score of 8 or less
Moderate Head Injury: GCS score of 9 to 12
Mild Head Injury: GCS score of 13 to 15
