Glasgow Coma Scale (GCS) Calculator

How to calculate Glasgow Coma Scale?

The Glasgow Coma Scale (GCS) provides a reliable and objective way of recording the conscious state of a person for initial as well as subsequent assessment.

GCS = E + V + M

Using the GCS calculator: an example

Consider a scenario where a patient shows Eye Opening to Sound, is Confused in their verbal response, and Obeys Commands during the motor assessment.

Step-by-step calculation

1. Assign E=3 for eye opening to sound.
2. Assign V=4 for confused conversation.
3. Assign M=6 for obeying commands.
4. The total score is 13, which is classified as a Minor Injury.

• 3 - 8: Severe Brain Injury
• 9 - 12: Moderate Brain Injury
• 13 - 15: Mild/Minor Brain Injury

Frequently Asked Questions

• What is the minimum GCS score?
  The minimum possible GCS score is 3. It is never 0, even in cases of deep coma or brain death.
• When is intubation usually considered?
  Medical professionals typically consider intubation and airway protection when a patient has a GCS score of 8 or less.
• Is GCS used for children?
  Yes, GCS is used for children. However, for pre-verbal children, the Pediatric Glasgow Coma Scale (PGCS) is preferred as it modifies the verbal and motor components to be age-appropriate.
