I have worked on two different IMCU's (Washington and Oregon) for the last three years, started as new grad. My current unit is at a 400+ bed hospital, 30-bed unit, ratios are3-4:1(more often 4). We have stable vent patients, all kinds of drips, septic, Gi bleeds, cardiac (MI, ACS, post cath etc), AMS, overdose, etc. I can honestly say that I have had the best learning experience on this type of unit. You have to be organized, independent, and ready for anything. My manager often says she thinks is it can be tougher than ICU in some respects because you have really sick patients but don't have as mush diagnostic equipment so your assessment skills have to be right on. I will also say that after three years I am beginning to burn out already. It's type of unit is very stressful and fast-paced. The patients can be very demanding and needy because they are so sick, and quite frankly a majority of the staff on my unit feel that 4:1 assignments are unsafe.That all being said, I do think you should try it. It might not end up being for you, but I can guarantee you that it will be one of the best learning experiences of your nursing career. Good luck!
