EMS does not save lives!
EMS provides a safe, efficient method of transporting passengers who have on-going medical illnesses or injuries.
If you think anything else....and work in the Helicopter EMS business you are part of the problem....not the fix.
You are not heroes, angels, or sky gods.....but good folks doing a valuable service to the community.
If a life is "saved" because of the rapidity of the transport....then that happens to be good fortune, good luck, or simply Fate working its way.
