Neurology In Critical Care
Glasgow Coma Scale
Eyes Open Spontaneously
To verbal command
The GCS is scored between 3 and 15, 3 being the worst
score, and 15 the best. It is composed of three parts:
Best Eye Response, Best Verbal Response, Best Motor
Response, as shown.
When doing a neuro assessment it is important to watch
for trends indicating a decreasing LOC.
Best Verbal Response Oriented and converses
Disoriented and converses
Keep in mind that when patients have ingested alcohol,
mind altering drugs, have hypoglycemia or shock with
a systolic BP <80, the GCS may be invalid.
Best Motor Response Obeys
Withdraws from pain
Important note, charting 'GCS 9' means nothing, it is
important to break the figure down into its components,
such as E3V3M3 = GCS 9.
A Coma Score of 13 or higher indicates a possible mild
brain injury, 9 to 12 is a moderate injury and 8 or less
a severe brain injury.
7 or less = Coma Total ___/ 15
