What are the three components of the Glasgow Coma Scale?

The GCS evaluates three categories of responsiveness: Eye Opening, Verbal Response, and Motor Response.

What is the range of a GCS score?

The scores range from a minimum of 3 (deep coma or death) to a maximum of 15 (fully awake and oriented).

Glasgow Koma Skalası (GCS)

Assess a patient's conscious state using the Glasgow Coma Scale, crucial for neurological evaluations.

The Glasgow Coma Scale (GCS) is the world's most widely used objective tool for assessing a patient's level of consciousness following a brain injury or medical emergency. By evaluating three specific areas of responsiveness—Eyes, Verbal, and Motor—clinicians can track changes in a patient's neurological status over time and communicate severity clearly to other members of the healthcare team. A GCS score is a vital component of the initial assessment in trauma bays and emergency departments globally, helping to guide decisions on airway management and the need for advanced imaging.

Nasıl Çalışır

The calculator sums the scores from the three categories. Eye response is rated 1-4, Verbal response 1-5, and Motor response 1-6. The total sum determines the overall GCS score, which the tool then categorizes into Mild, Moderate, or Severe based on standard clinical thresholds.

Hesaplama Formülü

GCS = E + V + M

Hesaplama Örnekleri

1. **Conscious**: Spontaneous (4), Oriented (5), Obeys (6) = **15**. 2. **Critical**: Pain (2), Incomprehensible (2), Decerebrate (2) = **6**.
