Initial Impression: Severe Traumatic Brain Injury with Skull Fracture Justification for F1 Classification: - Unresponsive patient with significant head trauma and agonal breathing indicates immediate life-threatening condition. - High probability of severe internal injuries and shock. - Time-critical intervention required to maintain airway and circulation. - Requires immediate ALS response and rapid transport to trauma center. Differential Diagnoses: 1. Severe Traumatic Brain Injury (high probability) 2. Spinal Cord Injury (high probability) 3. Hemorrhagic Shock (high probability) 4. Tension Pneumothorax (possible) 5. Cardiac Arrest (possible, given agonal breathing) Required Actions: - Dispatch of ground EMS with ALS capabilities and air ambulance support. - Immediate airway management and oxygenation. - Spinal immobilization. - Rapid assessment for signs of shock and internal bleeding. - Immediate notification of trauma center for activation.
