I work as an EMT (911) and resourcing is certainly a problem. In my small city, our response time is around 5 minutes, and if we need to upgrade to get paramedics, that’s maybe another 5-10.
However, if we are out on a call, out of service, or the neighboring city is on a call, now the next closest unit is 15+ minutes away.. sometimes there can just be bad luck in that nearby units are already out on multiple calls that came in around the same time, making the next closest response much further.
for a heart attack or unstable angina, the most an EMT will do (for our protocols) is recognize the likely heart attack, call for paramedics to perform an EKG to confirm the MI, administer 4 baby aspirin to be chewed and/or nitro (rx only), and monitor closely in case it becomes a cardiac arrest. If medics are far away we will probably head immediately to a hospital with a catheterization lab, or rendezvous with medics for them to takeover transport.
The few goals though:
- recognition (it could also be something equally bad/worse like an aortic aneurysm).
- aspirin to break any clots, assist administering nitro if prescribed.
- getting to a cath lab.
