I agree with Kann, that if your ultimate goal is to become a CRNA, skip the charge nurse bit. You need as much experience in critical care nursing as possible. I am assuming TICU stands for Trauma ICU. That would be OK, as well as CCU. You need to know your EKG rythms like the back of your hand. You should also have a strong grasp of hemodynamics, and vasoactive and inotropic drips. I also agree that CCRN is good to have. If you do not get in, I would also suggest if your hospital has a CV ICU to go there. You see alot of drips, swans, blood products, IABP, and sometimes VAD's or ECMO depending on your hospial. Best of luck to you.
