I LOVE PCU nursing. I work in a Heart and Vascular PCU. We do a ton of iv med with/without titration (ntg, amio, dilt, nicardipene, milrinone, dobut, dopamine, etc.) But the reason I love it- we get some critical patients- but I CAN TALK TO MY PATIENTS. That is so huge for me- I am a very "how does the patient feel" kind of nurse. If their BP is 70/40 but the patient feels ok- my worry factor is way lower than if I was looking at the #s alone. All in all- I wouldn't trade my PCU job for anything.
