The Pediatric GCS Calculator adapts the Glasgow Coma Scale for infants and children who cannot follow adult verbal instructions. Select responses for Eye Opening, Verbal Response, and Motor Response using age-appropriate criteria, and get the total GCS score along with a severity classification and clinical interpretation.

The Pediatric GCS adapts the verbal response component to account for children who are pre-verbal or too young to follow adult language commands. Instead of assessing orientation and conversation, it evaluates age-appropriate behaviors such as smiling, cooing, crying, and consolability. The eye opening and motor response components remain largely the same.
A normal, fully conscious child should score 15 on the GCS (E4 + V5 + M6). Scores of 13–15 indicate mild neurological impairment, 9–12 indicate moderate impairment, and scores of 8 or below indicate severe impairment — typically requiring immediate airway management and urgent evaluation.
A GCS score of 8 or below is the widely used threshold for considering endotracheal intubation to protect the airway in both adult and pediatric patients. Clinical context and trajectory of the score are equally important — a rapidly declining score may warrant intervention even above 8.
Yes. The pediatric adaptation is specifically designed for infants who cannot speak or follow commands. The verbal score is based on vocalizations (cooing, crying) and social interaction (smiling), while the motor score assesses spontaneous and withdrawal movements rather than command-following.
If a component cannot be tested — for example, eye opening cannot be assessed due to swelling, or verbal response cannot be assessed due to intubation — it is documented as 'NT' (not testable) rather than scored as 1. The total should then be interpreted with this limitation in mind.
A GCS of 3 is the lowest possible score, indicating no eye opening, no verbal response, and no motor response to any stimulus. This represents deep unresponsiveness and is a critical medical emergency requiring immediate evaluation for causes such as severe traumatic brain injury, hypoxia, or metabolic crisis.
Yes, the GCS is commonly used as a prognostic indicator alongside other clinical findings. Lower scores at presentation and failure to improve over time are associated with worse neurological outcomes. However, GCS alone should not determine prognosis — it must be interpreted alongside imaging, clinical history, and the mechanism of injury.
Abnormal flexion (score 3), also called decorticate posturing, involves flexion of the arms with extension of the legs and suggests damage above the level of the midbrain. Extension (score 2), or decerebrate posturing, involves extension and internal rotation of both arms and legs and suggests more severe brainstem involvement. Both indicate serious neurological compromise.
