Formula: Total GCS = Eye (1-4) + Verbal (1-5) + Motor (1-6). Range 3 to 15 pts. GCS 13-15: Minor TBI; GCS 9-12: Moderate TBI; GCS ≤ 8: Severe TBI (Intubation indicated).

In-Depth Guide & Mathematical Methodology

🧠 TBI Severity & Airway Intubation Threshold

GCS 13 - 15 (Minor TBI): Intact consciousness. CT head indicated if high-risk features present (Canadian CT Head Rule).

GCS 9 - 12 (Moderate TBI): Lethargy or confusion. Immediate CT head and neurosurgical consultation.

GCS ≤ 8 (Severe TBI): Coma. ⚠️ Secure airway immediately via RSI intubation. High aspiration risk.
