WHO decided where are EMT's go? We have a limited number of rescue squads, and even more limited Emergency Care units. IF they get a call for an overdose, and a family man down in his front yard possibly having a heart attack who decides who gets the last ambulance available?? Will they divert an rescue squad on the way to an OD when a call like mentioned above comes in?? How about a family in a car accident?? Husband, wife and kids in need of emergency care??
With the volunteer system in SoMD as a backup, we rarely run out of ambulances. In places like DC where ambulances are a constrained resource, we already have cardiac patients dying while paramedic units are tied up with addicts and their choices.
