Too few protocols to chart yet (protocols in brackets): ACS / chest pain (3), Alcohol withdrawal (1), Bradycardia (2), Cardiac arrest (2), Dystonic reaction (2), Eclampsia / pre-eclampsia (1), Hyperthermia (3), Hypothermia (1), Nausea / vomiting (3), Organophosphate poisoning (1), Mild to moderate pain (4), RSI induction (2), Wide-complex tachycardia (1)

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