we have the Vscan (not dual probe) in SICU, MICU, VAICU, CVICU, and CCU (and several attendings have). Its infinitely useful if you are running around a hospital, (ICU fellow going to codes, forced into CT scanner, out in the parking lot etc..) or have a quick question on ICU rounds. In the ed yeah sure you have an US machine in your dept which has more features than I have with the Vscan so I am not sure how useful it would be there? My questions are usually very simple with v scan like PUMP, tank, pipe kind of questions. However, if I'm looking for degree of valvular insufficiency, VTI, valve area of something more complex I use the phillips sparq, its pretty damn sweet (wish they paid me something for saying that).
