How is severe traumatic brain injury commonly defined in terms of the Glasgow Coma Scale?

Explanation:
A very low level of consciousness on the Glasgow Coma Scale signals severe traumatic brain injury. The Glasgow Coma Scale ranges from 3 to 15 and assesses eye opening, verbal response, and motor response. A score of eight or less is the standard definition for severe TBI because it indicates coma and a significantly reduced ability to protect the airway, requiring urgent airway management and intensive care. Scores of nine to twelve describe moderate injury, while thirteen to fifteen describe mild injury. While a deeper impairment can fall into a subrange like three to six, the widely used cut-off for labeling severe injury is eight or below, capturing the most critically impaired cases.
