What is the key to avoiding lightning strikes?
Roughly _______% of lightning strikes are fatal.
Initial treatment of lightning strike victims should focus on ______ ______.
In a mass-casualty lightning strike, what type of triage should be utilized?
"reverse triage" This means that resources should be directed towards victims who do not have pulses, and/or who are not breathing spontaneously. Treatment should follow standard CPR protocols; expect longer than normal periods of assisted rescue breathing
Why should "reverse triage" be used in lightning strike mass-casualty incidents?
Because victims that ARE breathing spontaneously and DO have a pulse also have a VERY HIGH LIKELIHOOD OF SURVIVAL.
