The GCS Calculator helps medical professionals quickly and accurately assess a patient’s level of consciousness using the Glasgow Coma Scale. The interface is designed for efficiency in clinical settings while providing educational context about the assessment.
Glasgow Coma Scale Calculator
Assess the level of consciousness in patients with head injuries or neurological conditions
About GCS
- The Glasgow Coma Scale (GCS) is a neurological scale
- Used to assess a person’s level of consciousness after brain injury
- Developed by Graham Teasdale and Bryan J. Jennett in 1974
- Widely used in emergency medicine and intensive care
- Scores range from 3 (deep unconsciousness) to 15 (fully awake)
Clinical Significance
- Helps determine severity of brain injury
- Guides treatment decisions and prognosis
- Used to monitor patient progress over time
- Critical component of trauma assessment
- Part of APACHE II scoring system in ICUs
Assessment
Note: The GCS should be assessed by trained medical professionals. This calculator is for educational purposes only and should not replace clinical judgment.
Results
Normal Consciousness
Patient is fully alert and responsive
| Category | Response | Score |
|---|---|---|
| Eye Opening | Spontaneous | 4 |
| Verbal Response | Oriented and converses | 5 |
| Motor Response | Obeys commands | 6 |
| Total GCS | – | 15 |
Clinical Note: GCS should be documented as E + V + M = total (e.g., E4V5M6=15). Always assess and document each component separately.
How to Use This Calculator
- Assess the Patient: Evaluate the patient's responses in three categories:
- Eye Opening: How the patient opens their eyes
- Verbal Response: The patient's verbal responses
- Motor Reqasponse: The patient's physical responses
- Select Responses: For each category, click on the response that best matches the patient's behavior. The calculator automatically updates as you make selections.
- Review Results: The calculator will display:
- Total GCS Score (ranging from 3 to 15)
- Interpretation of the score (severe, moderate, or mild impairment)
- Visual Indicator showing where the score falls on the severity scale
- Detailed Breakdown of each category response and score
- Document Findings: Note the results in the patient's medical record using the standard E + V + M = total format (e.g., E4V5M6=15)
The calculator provides immediate visual feedback and interpretation to help medical professionals quickly assess a patient's neurological status.
