Feb cardioq is too fiddly to use and displaces easily. add to that the risk of oesophageal trauma and the recent introduction of edwards lifescience's vigileo monitoring which is much more accurate and safe and preferred (by me and my colleagues at least). You'd have to look away from anaesthetists to sell that one (I've used it and don't particularly fancy it). try the physicians, they can't do arterial and central lines (and don't give a toss about oesophageal trauma).
My nomination for 2007 is RIFT. too much worldwide interest in PNG to ignore. The upcoming commercialisation faesability report is most likely to be very positive. plus the results of the seismics - make this too good to resist a punt on for 2007.
