It depends on the ED. We utilize both ED techs and clerks. Our clerks have little to no patient contact, while our ED techs do nothing BUT patient care. All of our techs are Paramedic/EMT's and are used in every aspect of the ED. We respond to codes, work traumas, transport to OR, assist with procedures (chest tubes, reductions, lacerations), draw labs, and perform triage. I would re-check the application and make sure that you did not apply to a clerk position. If it is in fact a tech postion, just know that there are better opportunities out there to use your skill set!
Best of luck!
