I have been working in PACU for the last 7 years and am returning to an open heart intensive care unit in a few weeks. I remember seeing a nifty little gadget about the size of a calculator and it did include calculator features with it. It was a critical care pocket guide that listed things like common drips used - how they're mixed - major algorithims - cardiac calculations and just a host of great info all contained in a pocket sized gizmo that looked and functioned as a calculator. Just can't remember who makes it and where I can get it. Anybody know? Thanks.
