In the CVICU you will see primarily post open heart patients, but also patients with every other problem under the sun because they need ICU care and the other ICUs were full. MI's, strokes, head injuries, diabetic problems, sepsis, drug over doses, it could be anything! (well, not kids or burns) In the other ICUs you will *NEVER* see an open heart patient fresh from surgery. In CVICU you'll see all the life support machines that have been invented, and work with every drug known to man (even investigational drugs not yet cleared by the FDA). Sure, it's scary as hell, but that's what you want, right?
I'm not knocking the neuro, cardiac, or medical ICU's - lord knows that they get their share of train wrecks, but if you're looking for the adrenaline rush that you see on TV ... plus THEN SOME, CVICU is where you should be.
