Enter the scores for eye opening, verbal response, and motor response into the calculator to determine the GCS score. This calculator can also evaluate any of the variables given the others are known.

Gcs Formula

The following formula is used to calculate the Gcs (Glasgow Coma Scale) score.

GCS = E + V + M

Variables:

  • GCS is the Glasgow Coma Scale score
  • E is the score for eye opening
  • V is the score for verbal response
  • M is the score for motor response

To calculate the Gcs score, simply add the scores for eye opening, verbal response, and motor response. The maximum possible score is 15, indicating a fully alert person, while a score of 3 indicates deep unconsciousness or death.

What is a Gcs?

A GCS, or Glasgow Coma Scale, is a neurological scale that aims to objectively measure a person’s level of consciousness after a brain injury. It assesses three categories: eye opening, verbal response, and motor response, with scores ranging from 3 (indicating deep unconsciousness) to 15 (indicating full consciousness). This scale is widely used in healthcare settings to monitor the severity and progression of a patient’s brain injury.

How to Calculate Gcs?

The following steps outline how to calculate the Glasgow Coma Scale (GCS) using the formula GCS = E + V + M:


  1. First, determine the score for eye opening (E).
  2. Next, determine the score for verbal response (V).
  3. Next, determine the score for motor response (M).
  4. Finally, calculate the Glasgow Coma Scale (GCS) by adding the scores for eye opening (E), verbal response (V), and motor response (M).
  5. After inserting the variables and calculating the result, check your answer with the GCS calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge:

Score for eye opening (E) = 4

Score for verbal response (V) = 3

Score for motor response (M) = 5
