ER tech job
You don't need phlebotomy license at all ER tech spots but experience is usually a must for the position unless you "know" someone.
A good idea might be to work as a transporter and get an "in" with the ER and try to get hired once they know you.:P
Probably not common I would think...usually the Docs are not doing the CPR so they can ask questions, Order drugs, order tests, and figure out the plan. I think CPR would take away from the concentration...also there are usually Lots and lots of people in the hospital to take turns on the CPR...
