This review article reminds us that circulation needs to be prioritized over airway in trauma patients. This means bleeding control (pressure on wound, tourniquet, surgery/IR intervention), correcting tension pneumothorax, correcting pericardial tamponade, as well as resuscitation to return physiologic homeostasis (blood products, vasopressors where needed, warm the patient, etc.) before intubation.  Altered mental status/low GCS may be due more to hypoperfusion than neurologic injury. Correcting the hypotension may alleviate that need to intubate.
