GCS Calculator (Glasgow Coma Scale)

Assess level of consciousness and brain injury severity using the Glasgow Coma Scale

Calculate Glasgow Coma Scale (GCS)

Example Calculation

Patient After Brain Injury

Clinical Presentation:

• Opens eyes when you speak to them

• Can hold a conversation but seems disoriented

• Flexes elbow and wrist when pressure applied to nail bed

GCS Assessment

• Eye Response: 3 points (opens to voice)

• Verbal Response: 4 points (confused/disoriented)

• Motor Response: 4 points (flexion/withdrawal)

Total GCS Score: 11 points (Moderate brain injury)

GCS Score Ranges

13-15

Minor

Mild brain injury

9-12

Moderate

Moderate brain injury

3-8

Severe

Severe brain injury

Understanding the Glasgow Coma Scale

What is the Glasgow Coma Scale?

The Glasgow Coma Scale (GCS) is a neurological scale developed in 1974 by Graham Teasdale and Bryan Jennett at the University of Glasgow. It's used to assess the level of consciousness and neurological functioning in patients with brain injuries.

When to Use GCS

  • After any major trauma
  • In cases of loss of consciousness
  • Suspicion of brain injury
  • Patients in intensive care units
  • Serial neurological assessments

Clinical Significance

Prognostic Value

GCS scores correlate with patient outcomes and mortality rates. Lower scores indicate more severe injuries and poorer prognosis.

Treatment Decisions

GCS scores guide critical treatment decisions, including the need for intubation, surgical intervention, and level of care required.

Communication Tool

Provides standardized way for healthcare teams to communicate about patient status and track changes over time.
