Too few protocols to chart yet (protocols in brackets): Asystole / PEA (3), Bradycardia (6), Burns (3), Hypotension / shock (2), Obstetric hemorrhage (1), Narrow-complex tachycardia (1), Tricyclic overdose (1), Traumatic arrest (1), VF / pulseless VT (2)

Doses far off from what other protocols give are likely misreads, so they are left out until checked. How that works.
