No, not to things like sickness, weakness , abdominal pain, falls with no LOC, minor MVC, and what they call "emergency transport" which can be stuff like bouts of colitis, feet swelling, bloody nose, or any of the myriad of ridiculous reasons people call 911
*This is the thinking that makes needing a medic on scene even more important! Sickness calls are some of the worst pts. "Weakness", why are they weak? Cardiac, sepsis, dehydration? Abd pain? What is the cause? "Falls", why did they fall? Syncople episode? " minor mvc"? Have seen many deaths from these. All from bad assessments.*
All of our dispatchers are EMDs, its pretty much a requirement to work at any PSAP or PSDC.
*Most systems are EMDs. This is nothing spectacular and dispatch mistakes happen all the time.*
But for an unconscious, regardless of the cause, we get ALS. Besides the obvious chest pain, LOC, breathing problem, arrest, allergic reaction, diabetic, we also get ALS on any OB call, any vehicle roll-over, and any time the dispatcher isnt sure what is going on
As said previously, this allows the ALS to respond, do an assessment and then determine if this is something they need to treat or something that can be turffed to BLS and they can become available. In my suburban town we have two medic units (P/P) within 5-10, 2 more at 15 and then like 4-5 units at 20. We obviously share our medic truck with a few surrounding towns, but we are the busiest system by far. In the three years i have worked here there was one time i needed ALS and did not have them.
In some cities it can be as many as a 6-7 als trucks being supported by 12-15 bls units
