Hello
Since I am an ER Tech, i thought I 'd post to this question.
I assume, EMT-Bs with training are allowed to start IVS/draw blood. In maryland, EMT-Bs cannot.
Also, when working as an ER tech, you are practicing under the hospitals policies and NOT as an EMT. As an EMT outside the hospital, you are practicing under the medical advisor that writes your protocols.
Now, being and EMT with actual riding experience is good for both medical and ER Tech work-even though most ERs will choose someone with some hospital experience+EMT than someone with just EMT.
Phlebotomy, for the sake of being an ER Tech, is not a big deal and I would defintly NOT spend $300 taking a course, if you don't have to. As an ER Tech, you would be taking vital signs, helping nurses, doing EKGs, etc....and phelobotomy would be one small part of that. It takes a matter of 4 hours to learn what you need to learn and be good enough to at least try yourself. It takes weeks or months to get the experience you need to be confident at it and attempt the harder-stick patients.
Hope this helps
