Too few protocols to chart yet (protocols in brackets): Allergic reaction (1), Beta-blocker / calcium-channel-blocker overdose (1), Crush injury (3), Hyperthermia (1), Post-ROSC care (1), Preterm labor (4), Status epilepticus (1), Tricyclic overdose (3)
Doses far off from what other protocols give are likely misreads, so they are left out until checked. How that works.
