ICU experience for CRNA

Dear friends,

I am working on in a level 2 hospital, on a floor that has 26 beds with trauma/med-surg/and neuro ICU all together. I am trying to get ready to apply for CRNA school, and also attending to rn-bsn program. I have been hearing that anesthesia schools value CVICU more than the others. Should I change to CVICU at some point before applying to CRNA school? Can I get some recommendations please??

Thanks a lot in advance.
