Hi!! I've worked ER/Trauma for the last two years now fresh out of nursing school. I'd like to try my hand at ICU. Any suggestions on how to prepare myself? I know that basics when it come to acid base balance, fluid and electrolytes and initiating vasoactive drips, but by the time I can actually gather everything up to take a closer look, it's time to ship them to the unit. You know the ol saying... if you don't use it you lose it. I guess I really just want to be able to interpret everything a little quicker.
