Well, unfortunately you're question is poorly formed. Our protocols are not state wide, they are county by county. But, I'll do the best I can to address your questions.
Do we Johnny and Roy everything?
I don't know what this means. But LACo hasn't changed much since that show aired, so for them at least, probably. (I have a great distaste for LACo EMS)
What is an MICN
Mobile Intensive Care Nurse. I'm not aware of anywhere that uses MICNs out of the hospital, despite the name MOBILE. Everywhere I know of, the MICN is who answers your radio call in. MICNs received additional training on prehospital protocols to help them help us.
Can we autonomously do things?
We have standing orders just like anyone else. What we have standing orders for varies by county.
Places like LA County offer very little in the way of interventions before making base contact and asking for permission.
Where I work, we have much more leeway. For example, we have Level 1 protocols, and Level 2 protocols.
I can preform any Level 1 protocol prior to base contact. I am supposed to make base contact before initiating Level 2 protocols unless...
"In the event a paramedic at the scene of an emergency or during transport ... reasonably determines that a delay in treatment may jeopardize the patient, the paramedic is authorized to provide any LEVEL I Paramedic treatment protocol as well as any LEVEL II Paramedic treatment protocol."
Our medical director also allows us to use clinical judgement, rather than being a robot paramedic with the following excerpt from the opening pages of our protocols...
"If necessary based on physiological
justification, a paramedic may modify protocol treatment sequence. Any variation from
treatment sequence shall be thoroughly documented on the PCR Narrative."
