Fifteen-point scale for expressing a person’s level of consciousness, from fully awake to deep unconsciousness, in a number: the so-called EMV score.
The Glasgow Coma Scale score or EMV (Eye-Motor-Verbal) score is a scale to measure the extent of consciousness, based on eye, verbal and motor responses to specific prescribed sound and pain stimuli.
Purpose
The GCS score provides the opportunity to document a clinical observation of a patient’s conscious state with a validated instrument which makes use of a patient’s responses to stimuli.
Evidence Base
The Glasgow Coma Scale is used to evaluate a patient’s consciousness by means of three elements:
opening eyes (eye response);
answering questions (verbal response);
motor response.
The three response values are looked at individually and as a whole. The total is referred to as the EMV score. The minimum total score is 3 and the maximum is 15. A slightly altered scale is used for infants (age 0-2) and toddlers (age 2-5).
The EMV score can be expressed as a combination of each of the three individual scores, such as: E3M2V4 (opens eyes when spoken to, arms stretch in response to pain and patient produces incomprehensible sounds).
If one of the EMV elements cannot be evaluated - such as might be the case if a patient is intubated and incapable of verbally responding, or is paralyzed/weak and incapable of fulfilling the motor request, then the individual score is included (score 1), but with an extra comment.
V1T is used for an intubated patient, in which t = 'tube'.
Clinical decisions must be based on each of the specific data of the eyes, motor and verbal responses and, if evaluation is not possible, an explicit explanation.
Standard values for the total score, depending on age:
0-6 months : 9 and up
6-12 months : 11 and up
1-2 : 12 and up
2-5 : 13 and up
> 5 : 14 and up

Best eye response to a stimulus. The element is mandatory, but does not require a numerical value. If no value is given, the reason for this is to be provided in the ConditionsDuringMeasurement concept.

Best motor response to a stimulus. The element is mandatory, but does not require a numerical value. If no value is given, the reason for this is to be provided in the ConditionsDuringMeasurement concept.
281396004 Glasgow Coma Score motor response subscore
Best verbal response to a stimulus. The element is mandatory, but does not require a numerical value. If no value is given, the reason for this is to be provided in the ConditionsDuringMeasurement concept.
281397008 Glasgow coma score verbal response subscore (observable entity)
The sum of the EMV scores, expressed as a number on a scale from 3-15. The value does not have to be recorded, as it can always be calculated based on the individual scores, and as recording the total is not common for a difficult to determine individual score.

ConditionsDuringMeasurement
0..*
Conditions during the measurement that prevent one or more of the subscores from being determined (non testable), such as,e.g. intubation during testing of GCS_Verbal.
