Knock down gas
Hydrogen sulfide - causes rapid loss of consciousness
How does hydrogen sulfide work
Inhibits cellular aerobic respiration
Most common cause of death in crush syndrome

Time vs distance in radiation exposure
Time - linearly cumulative
Distance - exposure reduced by square of distance
When does transmission of viral hemorrhagic fever occur
Later stages of illness when patient suffers vomiting, diarrhea, shock and bleeding
Time for 70-80% chance of conversion in v fib if shocked
Within 3 minutes
When to initiate care in hot zone
When medical care can be accomplished without risk to rescuer
Only tourniquets and life threatening hemorrhage
Order of management for bleeding
- Direct pressure
- Tourniquet application
- Wound packing
if in safe area and ample resources
When to initiate PEP for meningitis exposure

If in 12 hours a large number of people have sudden onset of high fever and hemoptysis, think what?
Tx for exposed EMS?
Think pneumonic plague
7 days of surveillance and doxy
PEP for Ebola

94% sensitivity and the physical exam has a 54% sensitivity of detecting medical causes of the agitation
Medical branch in ICS
Operations section - manages the operational medical resources responding to and mitigating the situation (e.g. EMS group, treatment group)
