I have worked ICU, CCU, ED and CTCU and never had a "tele tech". As a nurse we were responsible to watch the monitors for our patients and to cover another nurse when they or I became busy and had to away from the monitors. I would not want to take the word of an unlicensed and possibly undertrained person when I have to deliver some very dangerous medications. I have heard of some very competent "techs" but my gut tells me a trained RN or tele trained LPN is best.
