As I tell any EMT riding with me:
I'm just here for the narc keys.
Every patient needs BLS care, only a very few need ALS care
in addition.
The only difference between an EMT and a Paramedic is education, and I've met plenty of EMT's who have closed that gap.
You're operating as a team and happen to represent the only part of the team who has a job to do on every call. I expect EMTs to develop a plan of care with me, often times in parallel to my actions. We're both clinicians, but with a different scope of practice.
When the EMT/Paramedic team is working properly, the EMT shouldn't have to wait on the go-ahead from their Paramedic partner to apply oxygen or setup a nebulizer or acquire a BGL or a 12-Lead or vitals or administer aspirin, etc.
When you decide who is lead on the call, they take the history while the other "performs skills".
Patient assessment and history taking is not a Paramedic skill.
However, on an ALS call it is usually best to let the Paramedic handle the talking so they can gather a plan of care in their head. I don't personally care if an EMT takes the lead with questioning, just be prepared to keep asking the questions
I think a lot of EMTs are worried about being corrected, but being corrected is Ok. We may disagree on a treatment plan and likely the Paramedic has a reason for their plan. Sometimes you may be the one who is correct! There is a right way to handle differences in a treatment plan, and usually it is best to offer your plan as a question a Paramedic can answer.
What is a bad thing is when a partner is not willing to admit they don't know something. A lot of EMS ends up being On the Job Training, so admit when you need instruction early.
Hopefully you get a like-minded paramedic partner so that you can practice to your fullest and learn to operate as much as an individual but as a team.
