In patients suffering from non-traumatic cardiac arrest who exhibit ventricular fibrillation refractory to standard<unk> , two<unk>  shocks may be considered.  This is termed<unk>  sequential<unk><unk>  (DSED) and has been shown to have some effect in terminating VF, though existing data on neurologic outcomes conflict.  Several large EMS systems currently use DSED in their standing medical orders.
Double simultaneous external defibrillation
Transcutaneous pacing
Synchronized cardioversion
Transvenous pacing
Defibrillation
Prehospital protocol pediatric shock
Resuscitative endovascular balloon occlusion of the aorta
Awake intubation
