General approach per ATLS guidelines
Large bore PIV or central line access with blood products, massive transfusion
Establishing resuscitation airway
Bilateral thoracostomy, can do finger thoracostomies instead of tube or needle.
Emergency thoracotomy
If thoracotomy not indicated then pericardiocentesis or<unk>  ultrasound to evaluate for tamponade.
Consider REBOA catherization and balloon inflation
Long bone fracture reduction, if there is suspicion of significant enough hemorrhage
Pelvic binding
Surgical stabilization
Standard ACLS and BLS may delay critical interventions
No definitive animal or human evidence to support external chest compressions in<unk> 
No evidence to support IV epinephrine in<unk><unk> , with the exception of neurogenic shock

Traumatic cardiac arrest
Differential diagnosis should be thought of in terms of reversible causes
Spinal shock
Massive hemorrhage and hypovolemia
Cardiac contusion
Tension pneumothorax
Neurogenic shock
Hemothorax
